There may be a thermal cut-off switch inside that has failed. I've by-passed the switch myself, but don't recommend it. Another option is to replace the cut-off switch.

Add water light comes on when it is full


Try using warmer water. At 113 degrees our 2.0 finally admitted that the reservoir did in fact have enough water to operate. I filled the reservoir half full of drinking water and then heated other water in a water kettle. Just before it boiled I began pouring it in the reservoir until the Max level. To my delight when I pushed the continue button this time it worked. Customer Service had said to use luke warm/ room temperature water. For our Keurig, the water needed to be at least 113 degrees. Hope this helps.

Our brand new keurig mini plus wont heat or dispense water


I had the same problem with my Mini ! I also had this problem with my last Mini which was given to me and I tossed out. So I replaced with the new one which just went on the fritz. Called Keurig who were very helpful and told me to descale, but I explained the machine is almost new. So I prodded them for what else could cause the problem and its water that is too cold.

Turns out the problem is that I was using very cold water and the machine can sense the water is cold and will not heat. It does not heat so it wont damage the heating element. I was using 40 degree water from the fridge.

My symptoms were: I would fill it, that the blue light would flash, I would push the button, then the red light would flash and then nothing it would shut off after a while. Now with not so freezing water it works fine!

Hope this helps as I threw out a good machine because the water was too cold!

If Bunn unit has been stored for a while, how do i clean it and get it ready to use?


Hi, W/D here.
To get your Bunn working again, place a filter into the basket, fill the reservoir, and allow it to begin dispensing into the carafe. This will take several pots of water to get it filled and overflowing (dispensing). Plug it in, and let the reservoir heat up. It's not necessary at this point to have the heating plate turned on, but you can do so if desired to check that it is working, then turn it back off. Once you hear the reservoir heating up, pour in 8 ounces of white vinegar, and let the machine dispense into the carafe. Place an additional 8 ounces of white vinegar into the carafe, and pour back into the reservoir. Let the water heat up again, and let the vinegar solution sit in the reservoir for about 30 minutes. Top off the carafe with cool water and allow the carafe to cool with the warming plate turned off. After the 30 minutes, pour the contents of the carafe back into the reservoir, and it will dispense again. The water in the reservoir will heat up again. Check the coffee filter for residue. If you see a lot of grainy material, change the filter, and repeat the cycle until the filter comes out clean. Save your old filters as you go. Lay them out in order on paper towels, and you'll be able to mark your progress. When the filters clear up, discontinue recycling the vinegar solution and, instead, fill the reservoir with fresh water. The sediment has by now been freed up (de-scaled) and will continue to come off in smaller and smaller quantities. Each time you place fresh water in the machine, the dispensed liquid will smell less and less like vinegar. When no vinegar odor can be detected, you are finished.
Best regards, --W/D--

Left side will not heat after re-calibration of fill time


Check the hi-limit switch between the elements and or the thermal limit between element to lamp, and also check the thermostat.

Reservoir heats but won't dispense


If you are pouring water in the manual brew basin, then check the sprayhead holes, then the spray tube, those could be blocked. If using the auto brew, check the solenoid and or brew switch.

BT-10-B Bunn Thermofresh that will not heat or fill pot


Lots of times minerals clooect on the heating element and inside the heating chamber. The easiest thing to try is to put white vinegar into the filler, displacing some of the water into the pot. Leave this to soak for about an hour, then flush with several pots of water until the vinegar smell cannot be detected in the water. Make sure that the switch on the side is "ON". You may have an indicator light. The switch on the upper front is for the warmer. The reason you only got a partial pot of water is that the reservoir wasn't completely full. Once you have filled it completely, you should fet a full pot out for every full pot in. If all of the above gives you no relief, you may need to test the heating element for voltage and continuity. If it tests 'open', you will need to replace it.
Good luck, --W/D--

New Saeco Odeo Go has solid red exclamation mark, doesn't budge


You have to 'manually' prime the pump: When the red exclamation mark shows, press the water switch on the right side (the picture of the water drip), then open up the steam nozzle and let the machine pump hot water into a cup until the red light goes out.

CHECK THE BLACK WIRE COMING OFF THE BOTTOM TERMINAL OF THERMOSTAT FOR VOLTAGE, IT SUPPLIES POWER FOR THE WARMER SWITCHES. THE 'READY TO BREW' LIGHT IS PROBABLY A BAD BULB.
