Hey just bought new emerson 83721 maker, made three pots of joe and now it does'nt heat the water....light comes on on on/off switch but no action. removed bottom cover and did not see any broken contacts..could switch be bad?? I hate chinese junk but wife bought it...
Mine did this too just the other day. I figured its either the thermostat or the heating element. However, i traced the wires leading to the both and found what looks to be a Zehner Diode. Tested this, it appeared to be bad. Did a quick bypass test to test theory. Turned it on for a sec with Diode bypassed and i mean literally a sec. Element heated right up. I believe all i need to do is replace this bad diode and all will be fine. Maybe you have same problem??? Now if only i could figure out the value of the original so i can replace it properly. :)

Common problem, it is hard water issue, these coffee makers do not handle even slightly hard water as deposits build up quickly blocking water flow to element. Try one of the many coffee pot cleaners, but if it is as bad as described, may not be enough to clean out coils.
Sometimes coffee grounds get into the intake if you don't use the intake filter. Unplug, set the pot aside and then turn the coffe maker upside down in a sink with a good hose sprayer. Direct the water up into the intake side of the coffe maker with the filter out.
Then refill and see if water will flow through. If it works, run vinegar or a pot of water with a tablespoon of dissolved baking soda (dissolve in pot first or it will clog the coffee maker).
This can be caused by scale build-up on the thermostat probe that hangs inside the tank. The scale stays hot for a long time, tricking the thermostat into believing that the water is still hot. Try pouring 1 Qt white vinigar into the unit, let it warm up completely, run a pot of clear water thhrough the machine, then turn the unit upside down over a sink (making sure it's unplugged first, and always keeping the fill hole down at all times) to let it drain out all the way. Then before you plug it back in, pour water through the machine until water comes out the sprayhead. Then plug it in, let it heat up, pour 2 pots of water through the machine & see if it heats up properly. If this doesn't cure your problem, your unit may need to be completely dismantled to de-scale the tank & thermostat probe.
Leave the carafe off the hot plate and place the basket in holder with the lip under hinged flange so it sits flat. Then replace the carafe and the basket should not move up when the Pause and Serve button opens. I just bought this pot too and
love it but except for the basket placement problem.
