Keurig K155 Office Pro Commercial Coffee Maker, Single Serve K-Cup Pod Coffee Brewer, Silver, Extra Large 90 Oz. Water Reservoir

The best k-cup brewerDon’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!

I needed something that can handle a lot of use.Wish it had a strong brew option.As for coffee flavor depends on the brand not coffee maker.Like the big water reservoir.It works with all k-cups (my old one did not).

Yes, it can be plumbedRegardless of what you read K155, K150 and K150p (at least current versions) can ALL be hooked up to direct water using the optional kit. Just did this with K155 despite this caveat from manufacturer on the Amazon listing: “In addition, this brewer cannot be plumbed to a water line.” I suspect the confusion stems from the fact that this brewer’s basic design is a decade old and some changes have been made while the manufacturer’s comments on the listing, have not kept up. The photo is from the sanitizing manual that accompanied my machine. I replaced a failed K150p and used the old direct plumb kit. Further proof: 2nd pix is a cup of coffee (southern pecan, BTW) that I just made with this direct-plumbed brewer. PS: Raised in various newsrooms I have a 10-12 cup a day habit (caffeine optional) thus plumbing the maker a great feature.

Purchase the Protection Plan!The media could not be loaded.

I bought the K155 commercial brewer for home use mainly so I can buy the direct waterline plumbing kit and never need to refill the tank (yes, first world problems). I also installed an RO system for our drinking water which I tapped over to the Keurig. This combination has been bliss in achieving exactly what I wanted.Unfortunately, my first K155 lasted 26 months until recently (Texas snowmeggedon) I happen to need to reset a tripped breaker it was on and believe it caused a power surge and killed our machine. $250 over 26 months is less than $10/month, so I wasn’t terribly heartbroken, just coffeeless.I did call Keurig and spoke to an engineer about the issue and he told me these machines were not serviceable and it couldn’t be fixed. He did highly recommend the K2500 because it is serviceable, which I looked into, but it’s a bit more expensive and reviews we not that good. So I decided I’d bite the bullet and purchase another K155. Since I already have the $150 plumbing kit, this really made the most sense. I did add Amazon’s 4-year protection plan that seems to cover most possible electrical and mechanical failures that could happen. It also would have covered this power surge failure on this first one if I had it. So, if I get 4+ years out of this new one, I’ll be a happy camper.Overall it’s a great brewer. Paying $50 for the extended protection plan, in my opinion, is a smart buy. The brewer’s pump did get a little more noisy after a couple months, but always worked fine. The only issue I’ve had is I can’t seem to find a suitable reusable k-cup for brewing bagged coffee grounds. The interface is a bit different than the home machines so many of the designs don’t fit right. The one I found that did fit, doesn’t make a good seal on its top, so water spills over it instead of going through the coffee.Obviously, I’d buy the machine again, because that’s precisely what I did. It’s a little steep of an investment for a coffee maker once you add the cost of the plumbing kit (and water filtration), but if you can get the years out of it, the cost may be justifiable.

Buy the Warranty, it will breakWell you have a K Cup machine because you either a) like burned coffee flavor b) don’t like coffee c) need this for your office.If you had taste buds and liked coffee, you would have spent your $300 on the Breville Precision Maker with a Thermal Carafe or a Moccamaster and a decent burr set drip coffee grinder (Virtuoso +).Hopefully you are in choice C: You need it for your office.That being said, it does fine for hot water duties for oatmeal and makes k cups. They are very prone to breaking a year or two in. My office’s have had this machine or a relative of this machine for the past 5+ years and gone through 4 of them. Get the 4 year warranty, it will pay for itself…in the meantime…enjoy your burnt coffee brewed at too high of a temperature from nasty k-cups…because k cups don’t get any better that what they are.You get a 5 star for working fine and being easy to use and clean with a detachable water filter. You get a 1 star for reliability. 3 stars it is.
