Keurig K155 Office Pro Single Cup Commercial K-Cup Pod Coffee Maker, Silver

I had been a Tassimo user since 2005. My first machine lasted 7 years, and I loved the coffee. After the first machine died (it just stopped turning on), I immediately purchased another. Over the years, it's become increasingly harder to get pods for the Tassimo, especially the Extra Bold line. I didn't want to be limited to only getting refills on Amazon, and also being limited to a very small variety of brands and flavors. I decided it was time for a change. Like many, I was initially unimpressed with Keurig. The machines seemed cheap, and many reviews have said that they only last for a year with daily use. I always found the Green Mountain brand pods to be exceptionally bitter, and the machines never produced really hot water (if you add cream/milk it will be luke-warm). Perhaps my views are jaded from bad experiences in the past, but I knew I wanted to get a commercial quality brewer and that's how I found the K155. Fast forward to today. I've been using the K155 for two weeks now and absolutely love it. It's heavy and seems to be built to take abuse. It holds 90oz of water, which reduces the frequency of refilling. There's about a 3 minute warm-up time in the mornings, but subsequent cups will be much faster. Using the machine is dead simple - just put in a pod, select your cup size, and hit brew. If you just want hot water, you can press brew without a pod inserted and the machine will dispense it. As for the coffee, it's been very good! Keurig includes a 12-pod variety pack with the brewer, and I've also purchased some more at the supermarket. I love the McDonalds McCafe French Roast - it's an incredibly smooth dark roast that is delicious with cream. My girlfriend loves the Donut Shop, which is a medium roast akin to Dunkin Donuts. For flavored coffee, the Cinnabon Cinnamon Roll is surprisingly good. For decafe, I've only tried Donut Shop so far, which I was also pleasantly surprised by. I'm not a huge fan of the design. It's very "industrial" looking. While it has a large color LCD, it displays random pictures of coffee beans while brewing. I would have preferred a status bar like my second Tassimo had. But I can get past these minor gripes due to the fact that it makes good, hot coffee with a humongous assortment of varieties. I definitely recommend the K155 if you take your morning caffeination ritual seriously.

This makes a perfect cup of coffee for me in a short period of time. I grind my own beans (to my own settings from a hopper in a Breville grinder) into a reusable pod which is not special in any way. I put the pod in the coffeemaker and that's it. (I've never really found a perfect cup of coffee from any of the many Keurig K-cups I've tried.) I also have used the cups, paper filters and lids sold by Amazon, but using the reusable pods just seemed easier to me. This is my second K155 type coffee maker and while the first one lasted about 7 years, I didn't feel a need to change coffeemakers. I was hoping this would use the same pods without restriction, and it does! (that was my biggest concern) My first coffeemaker died by starting to make a grinding noise when brewing and eventually the electronics failed and would not allow me to pick a cup size other than 10 oz, and it didn't even work at that setting, spewing about an ounce of water. I felt it died too soon, but $25 a year average for the coffee maker is okay for me; I really liked it and couldn't see me going back to anything else. NEW: After using for a short time I noticed that the coffee was not hot like my previous Kuerig 150 coffee maker, so I pumped up the brew temp to 198 degrees (highest it will go). Measured the results with a calibrated liquid thermometer and found that it was only 181 degrees, 17 degrees lower than requested. Thats why it initially seemed luke warm to me. Now I put the brewed cup into the microwave for 20 seconds to heat it up. I will have to give it 3 stars, not 5.

UPDATE: April 2020 — After nearly 4 years of heavy daily use, this coffee maker is still going strong. We’ve cleaned it several times and have had no issues or problems with it. I would have liked to have the direct feed water line attachment for convenience but other than that, no complaints at all! Well done Keurig!! ================= Sept 2016: I was a little skeptical at first because our previous Keurig 2.0 only lasted about 13 months (of course just after the warranty expired) but I am usually a proponent of buying "commercial" grade products for their durability - the adage of "Go big or go home" has merit! So we're still in the honeymoon stage with this brewer at just under a week but, I find it to be much a better made product than the previous Keurig we had and it also seems to brew a little quicker too. I thought I'd address a key point that some others had complained about: [TASTE] Whenever I buy a product that use for drinking, eating, etc., I always wash it first, I'm sure nearly everyone does that. After reading that some people had a bad plastic taste in their coffee and couldn't get rid of it, I went into this with my eyes open. Upon opening it and washing it the first time, I too smelled a strong plastic smell and having some experience with sanitation methods, these are the steps I took to eliminate this taste issue. Be prepared, it takes some time but in the end its worth it. Step 1: Fill the reservoir full of hot water leaving room to add about 3 cups of "other" liquids Step 2: Finish filling the reservoir by adding 1/2 cup of regular bleach, [unscented!] and 2-1/2 cups of distilled white vinegar. Step 3: Let soak until water cools off Step 4: Wash the reservoir with dish soap, I prefer to use the regular Dawn soap but I suppose any will do. Step 5: Fill the reservoir 3/4 way with filtered or bottled water and add 2 cups of distilled white vinegar. Step 6: Without putting a pod into the brewer, run just the vinegar water through the system until it signals you the reservoir is empty. Step 7: Begin filling the reservoir with more filtered or bottled water and repeat step 6. Step 8: Repeat steps 6 & 7 above until you can no longer smell the vinegar in the hot water in the cup. By this time, you should have a cup of hot water that has no vinegar smell and absolutely no plastic smell. I discovered that it took about 20-25 cups to process mine, I wasn't actually counting but figured based on how much water I poured through it. Now I'm looking forward to great coffee - as is always the first step to any good cup of coffee, the water, be sure to use filtered or bottled water as straight tap water has a lot of calcium and other things that can make coffee taste bad. Enjoy! Hope this helps others with their new machine!!

Don't turn up your nose at the Keurig brewer. It can make decent coffee quickly and you can use your own ground coffee if you want to reduce waste. This brewer looks large but it really is not much bigger than the lesser Keurigs. It is a heavy machine, about 18 pounds. It's mass may be why it is so much quieter than any other Keurig brewer I have tried. The construction is a level above the residential models. The brew chamber operates smoothly and there is an extra pressure plate in the brew head that stabilizes the pod while being clamped. What I enjoy about this machine is its simplicity. I don't have to puzzle over an array of push buttons, most of which I don't care about but require my attention for every brew. Many complain about the lack of 12 oz size which I don't lament at all. That's the size you would select if you want a weak and bitter cup of coffee. There just is not enough coffee in a k-cup to make a decent 12 oz cuppa Joe. I use 8oz exclusively and since that is always the default size all I have to do is press "Brew" after I close the lid. From start of drip to last burst of air it takes about 50 seconds to extract a cup. This speed should ensure a poor cup of coffee but, surpisingly, in the Keurig system it works. Perhaps the slight pressurization of the hot water makes up for the short brew time, I don't really know. I do know the quality pods I use taste great. My favorite brand so far is Peet's. If you use the cheapest, most stale bargain pods you can find you will make awful coffee. I often use the 4oz size without a pod to preheat a cup and to get the brew compartment warmed up and cleaned. In fact, I use the 4oz rinse a lot because a clean machine is important to good coffee. This extra fussiness is not required but I am, by nature, a fussy person. I had tried the Keurig K-1500 and it has no 4oz size among other failings. (I found it to be very noisy and slow to heat. It also can't brew a second cup quickly, it has to heat up again.) I thought the K-1500 would be a cheaper and newer alternative to the older K-155 but it is miles away. Excellent aspects of the K-155 is that you can adjust the temperature within a 10 degree range. My test with an accurate thermometer shows the settings to be accurate. This amazes me because I see many review videos of other Kurig brewers where the temperature never even gets to 180. Keurig nailed the temp adjustment on this machine. I like that I can set the on and off times for the machine. It is ready for me in the morning and it obediently goes off at night. I drink coffee or want hot water all day so I don't use the 2-hour auto off function. I have two complaints. The first is that there is no backup for the time setting. If you momentarily use power the clock shuts down and so does the on/off setting and the auto off if you are using that one. How hard could it have been to include a button cell battery and a simple circuit to keep the clock alive? Very disappointing and annoying. My only other annoyance is the silly display. The little movie is repetitive and conveys information nobody was asking for. Why can't we choose to shut that down or suppress it. Both of these gripes are petty and not of much consequence. This brewer will give you your money's worth in decent quality hot coffee. My previous brewers have had fairly short lives and I am hoping this one will last. Oh, on a side note let me talk about using your own coffee. Keurig's left and right hands apparent do not communicate with each other. Keurig says you can't use a "my k-cup" in this brewer and that they don't sell one. That is only partially true. Keurig used to make a gray-colored my k-cup with a screw top. That has disappeared years ago and I can attest that it does not fit and that you really can't find them to buy anymore unless you go to the used market. So what does work. Amazingly the newer models works. These are the black ones with the big dot on the lid and the single hole in the middle. Just pop out the pod adapter and drop this in after being sure to remove the extra 2.0 device attached to the bottom. I'll attach a photo of the one I use. Keurig has just discontinued this item and replaced it with a 5-hole top version. This one also works with K-155 but Keurig does not seem to know that. There is a valve mechanism in the lid that closes off the 4 extra holes. Be aware that you must remove the pod receptacle in the head to drop a my-kcup. I see so many complaints from folks saying these don't fit and they include photos of it sitting atop the pod adapter. So, yeah, it won't fit if you can't read instructions. Thank you!

Bought this coffee brewer for my office October 27, 2025, received and installed it October 31, 2025. Brewer stopped working June 29, 2026, with the Error Message (Error Code 5 ! Over Pressure detected). Requested service help was connected to someone in India that spoke broken English. After trying several attempts to remove the error message. She sent me a link to upload Proof of Purchase and Serial Number, which I provided within the hour, same day. The following is Keurigs response to my claim, followed by my response to each statement: You must be looking at someone else’s information • Serial number is not valid. Serial Number is what is on the coffee brewer. • Proof of purchase provided is not valid. How is it not Valid it is an Amazon receipt for the purchase. • Proof of purchase shows a purchase date outside of our 1-year warranty. Purchase was made October of 2025 that is only 8 months ago. • Proof of purchase states brewer was purchased “Used.” Purchase was made on Amazon as NEW not used, you are incorrect in stating Used. • Proof of purchase provided is not from an authorized retailer. Purchase was made on Amazon by their Approved Retailer. If you don’t want to refuse to Warrant your products that is fine, but don’t lie about it. It just means you’re a shoddy operation. I will not purchase any future Keurig products. I would caution anyone purchasing from whomever Amazon is fronting for because they will Not Honor their product.

Deducted one star for not having a de-scale mode. You have to manually de-scale. I’ve had this machine for about a year. It’s a really good coffee machine. When you manually de-scale it make sure you pull the tank up and clean the inside of the tank and the filter that’s in there.

Its about the best Keurig built and at that price I hope it last quite a while. I have it in a high traffic office environment so it will get tested. Makes a cup pretty quick and brews up to 35 cups per water fill depending on the size choice per cup. Easy to use and quality I guess will depend on the brand I have been using the Walmart "Best Buy" and taste is "excellent" no complaints, but its free so----

Good machine, but for the price it should have a 12 oz. setting like many of the other smaller and less expensive machines. Be sure to drain the reservoir completely if you do not plan to use for an extended period of time as a water film builds up on the inside and interferes with the sensor. Tech support didn't have a clue when this happened to me.

Tan caro y solo me duro 37 días el producto en uso, ya se me descompuso y la ventana para regresarlo acaba de expirar hace 5 días!.. 😠 Y ahora que hago?

After all the reviews about bad plastic odours, defective water resevoirs, ect ect, I was really expecting to return this brewer (kept all the packaging) BUT, lo and behold, NONE of these complaints or defects were attribute to my purchase. Out of the box, no cleaning or cycling water I went kamikazee, filled the tank and immediately made my first cup. It was great, certainly not Starbucks, but for a 30 second prepared pod coffee, very, very acceptable. No odd flavours or plastic taste. The complaints of no 12 oz setting is easily circumvented by brewing a preset (its a 4 choice menu that is auto 8 oz, but all you do is choose another size) 8 oz cup, then do a 4 oz cup, easy as that, although it will be a tiny bit weaker than the 8 oz. The reason Keurig did this is that solo cups are MADE for the best result at 8oz, anything larger a little watered down and anything smaller a little stronger. Most K-Cups are not to my liking, especially the weird flavored ones (Krazy Kups), but I got the Columbian from Garabaldi, and they are super! I tried the Ethiopian and found them too weak in flavour. Dark roast is necessary to get a decent coffee taste from k-cups machines, I find. I bought this re-fillable: https://www.amazon.ca/gp/aw/d/B00WAT0Q62?psc=1&ref=yo_pop_mb_pd and it works just fine with the Keurig K155. I just quit my keurig 2.0 and could NEVER get the My K-Cup to brew anything acceptable. Weak and often filled with coffee grains, but the K155 brews a little differently (it prepares the water, then brews more quickly) and the re-fillable cup for $10 works fine (again it won't be a Starbucks) This K155 also will not brew K-Pods (for the carafe) and the k-cup holder ONLY will accomodate the small cups and not the larger carafe pods, which means your My K-Cup re-fillable for 2.0 machines won't work, but the one I linked above does work for the K155. The screen DOES have a very small clock (it has to, it has a timer), and in over a month the time is still accurate. The clock disappears when it scrolls through its various idle screens (totally an annoyance), and there is no setting to diable this, so clients critiques as to no clock are somewhat accurate. I don't understand, to be honest, why the settings are SO limited. You can turn the machine on via a clock setting, but why would you? It can't wake you up to a pre-brewed coffee, so I don't see the point. Also, it would be nice to turn on via the touchscreen but you can't, the power switch is on the back. A little awkward but no big deal. The tempurature is settable to scalding hot, something my 2.0 never achieved, and the brew sizes are dead on (4-6-8-10 oz, you choose after placing the k-cup) The 'build' of the machine is nice (but certainly fathoms away from a restaurant style chrome and steel machine) and as they market this as commercial, it is not robust enough for a commercial setting, although adequate for a 20 ppl office setting, providing everyone doesn't bang it around too much. It is all plastic, but looks sharp on any counter, and has the approx same profile and dimensions as the 2.0 It also has a port in the back for direct water plumbing but I believe it is an optional purchase for the hardware. Very important! The K155 has removed the DRM (digital rights management) from this machine, so any k-cup, whether Keurig sanctioned or not, will work. So, to end my review, this Keurig K155 is WAY, WAY better than its 2.0 cousin. It brews a piping hot cup as promised, and looks a whole lot better on the counter than the old machine. Basically, this is a souped up fancy home model. It brews faster, and better. It tastes richer, and you can get a decent cup from the re-fillable knockoff from my link above. It does cost a little more than double the 2.0, but if it lasts 3/4 years than the cost will be worth it I'm now off to throw out the box into the recycle bin. If anything untoward appears, I'll update and let you know - but so far, I am happy with the $ I spent. And Amazon Prime ships free, overnight! Java Ho!! *UPDATE - Have now had this brewer for over a year, and it maintains my 5 star review. No issues, works great, after a year of daily coffee making, still makes a quick, fantastic cuppa! I only use Death Wish, keurig Turbocharge or Gran Caffe Garibaldi (everything else is too weak) Still a great coffee machine after 12 months of use!

Recieved It Today, It's Very Nice, Huge Water Reservoir And Preheats The Water So It Makes Coffee Fast And Silent. The LCD Is Nice, But Isn't The Best In Terms Of Display Quality/Animations But Your Not Going To Sit And Watch It All Day, And It Does The Job Nicely. You Can Program Diffrent Things Like Clock, Temp, Auto On/Off Etc. The Power Switch Is In A Good Location Out Of Sight On The Back But Easy To Reach Without Going Behind The Unit. It Is Very Pricy Almost $400 And Probably Not For Everyone. It's More For Coffee Enthusiasts And Thoses Who Like The Best/Offices Etc. It Is Marketed As An Office Model But It Is Great For Homes. So Far I Am Pleased With My Purchase. Recommended If Price Isnt A Concern.

Purchased this 3 years ago (2021) for home personal use. It randomly stopped working. Black screen of death and it just makes a repetitive clicking sound when plugged in. Will not turn on or off, just clicks. After investigating, it is a known issue. For the price one would expect it to last much longer then 3 years. Prior to this, it was amazing! I purchased it after using the same one at my work for years. Figured if it worked for a busy corporate location, it would be above par for a home with 2 coffee drinkers. NOPE

I was not hesitant to purchase another Keurig as I have owned, and gifted away, several over the years. This was, however, one of the first commercial grade Keurigs I have owned, and we LOVE IT. We bought it for the entrance of our church, so that we had something that could keep up with the coffee demands. Super easy to set up, great size water reservoir, perfect brewing temperature, works great. Can totally see, in a year or 2, of upgrading to one that connects directly to a water feed...but until then we shall enjoy this one.
