I have a Keurig coffee maker model 155, very nice machine. However, it will not power up and work after a power failure. Is there some special reset button on this machine, perhaps?

I had a similar experience and had to dump the water, empty the coffee capsule and leave it unplugged for an hour. Make sure that ( if you have GFCI outlets) that they haven't tripped. After an hour plug your machine in and it should work as normal. Make sure that your cup sensor isn't blocked after all that cleaning.

I have asked my question twice It has not been answered yet WHY?

Hard call without seeing the failure.

No hot water? Does the heating light come on? If so, then the element is gone. Not economical to replace it.

Humming sound? What frequency? Is it a pump that runs continuously? If a tube is broke, it might be repairable. A bad pressure sensor will not be.

If the sound is a 60 cycle low hum you may have an electrical failure and possibly a dangerous machine. A wiring problem has a small possibility of repair.

The check engine code is 155 and 217

155 - Oxygen Sensor Heater Circuit , Bank 2 Sensor 1 217 - Serial Communication Link
The 217 code indicates the communication bus between two or more of your computers is malfunctioning. The 155 code is one of your rear oxygen sensors malfunctioning.

Keurig B66 coffee maker randomly stays on and brews.

I have called Keurig and gotten replacements for units... however... all keurigs will heat water... then stop... after a while, the water will get cool, and the unit will cycle on.
when you say shuts itself off, the whole unit does Dark?
If the whole unit goes dark, then you may have a bad overtemp sensor... most if not all appliances will have this featurew to shutdown everything if the sensors detect a higher then normal temperature.

If that's happening... call Keurig and tell them this,,, they should honor the warranty and ask you to send them you K-cup holder as proof of ownership... then you will get a replacement.
you now have a unit for parts or to sell on ebay for parts...

I can allways use the parts... :)

My keurig won't brew a full cup for the 10oz option, but it brews a full cup for the other options.

This sounds like a water level sensor inside the unit. If it's under warranty... call Keurig and they might send a replacement... out of warranty requires you to open the unit and re-seat the harness that comes off of the water level array into a circuit board... low voltage thing...taking it apart is not easy, but I have explained it in another answer... for a B70 unit...

I not get coffee out of my machine

My aunt has a Keurig and I just bought one for my mother and one for me because we like the coffee so much! Her coffeemaker was giving her trouble - not pumping water through. She tried every cleaning method recommended by Keurig, then she took a can of compressed air. like the kind you use to clean out computers. She put it over the opening as tight as she could as she did not have the "straw" on her can. The "clog" in the water tube dislodged and water sprayed out. (Do this when the machine is cool as hot water can burn!) Her Keurig is now working great!

Keurig stainless steel (not in the photo) H20 resevoir not worki

Keurig will allways blame this on using unfiltered water...only you know if this is true... or if you bought the unit used...
It could also be a internal sensor reading wrong information... i.e. water cold when it really is hot... intermittent connections going from low voltage sensors,valves and motors to the electrical circuit board...
We may need more info... but if out of warranty... you need some mechanical background to dismantle it and check for connections, if you insist the water is ok..... someone who opens the unit will tell my looking at the lines and the measuring unit probes...

Keurig coffee maker will not dispence water because the add water sensor will not go off

Have you tried to de-scale your coffe-maker, and rinse it thoroughly?

If yes, according to the user manual, page 15
You should call Keurig for support when it still says "add water"

Keurig b100

I think that the unit senses its emptiness via an optical device that triggers when the red indicator ball hits the bottom of the tube. It could be that the tube is dirty from deposits (calcium or whatever,) fooling the B100 into thinking the ball is still at the bottom.. Basically you'd have to open up the machine and see whats what, the tubes can be cleaned but if it is a defective sensor you wouldn't be able to get a replacement, but you could probably jury rig a way to defeat the sensor itself.

The units are serviceable if you are handy, but it isn't as simple as replacing a fuse...
