Wont heat water - Bunn 10 Cup Home Coffee Brewer

I'll need to know what make--model--- age of this unit is and if it's electronically controlled to help you----your question is too vague do to the enormous variety types of heating systems----I'm going under the info provided that this is a boiler with domestic hot water coil----you say central heating so this throws me off---do you heat with hot water--hydronic-----or forced hot air----if hydronic---it sounds like your circulator in not functioning----a bunch of reasons circulator has failed---aquastat's "circulator control" has failed---thermostat has failed----broken wires----plugged lines----it goes on and on----this is the best I can do with this info sorry Happy Rabbit

check to see if the suction passage on the machine is plugged.

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!

Check the water level. If the water is low it will not allow water into the heater core to produce heat. If there is water keep an eye on your temperature gauge It should reach at least 140 to 170 degrees. If it is staying colder than that you have a stuck thermostat which is allowing the water to flow to much and not let the engine warm up. The only other solution is if the fan is not working properly replace the fan relay for you blower.

If your DW has an "energy saver" or "no-heat" button for wash or rinse, make sure it is not selected.  If that is not the case then the heating element is probably burned out and needs to be replaced.

has the unit every been cleand you can check the it in the service door
