4. Check the temperature of the water.

The two round "devices" on the tank are the operational thermostat, and the "safety" overtemp thermostat. It is usually the "operational" thermostat that fails, since it has to cycle a lot and arc internally. It is usually about 120-140 degrees F., and the safety thermostat significantly higher.

you should be able to find what you need at the following site:

Hello! About 2 weeks ago, the same problem began on my Hamilton Beach water dispenser.
Last week, I called the HB service support, and they told me to do the following reset procedure:

1. Dispense 3 cups from the HOT water side, and also, 3 cups from the COLD water side.
2. Turn BOTH back switches OFF (the ones on the back of the water dispenser).
3. Unplug the dispenser, and LEAVE it unplugged for 24 hours.
4. After 24 hours, turn the back switches ON and plug it in.
5. Leave it on for 4 hours WITHOUT dispensing any water.

...it's been about 12 hours since I've dispensed water again for the first time, and so far, SO GOOD! I'll update if the problems reappear.
