Water heater (indicator light) not heating, may be due to: 1, heating tube burned; 2, temperature controller is bad. Elimination method: 1. Replace heating tube; 2. Replace temperature controller. Water heater can not heat the specific situation, the first situation: water dispenser is not electric, not heating, not refrigeration.
3. socket connector, that is, the contact of the plug is bad. (or the zero line of the plug is broken so that you can have electricity when measuring the socket, and there should be electricity in both lines at this time.). 4., the water heater power line oil in long-term use, it may be broken inside, as long as one of the broken line, so that the water dispenser no power input. 5. the internal power input part of the water dispenser is corroded and oxidized and broken due to a long time in a humid state. Third: the temperature control switch is tripped, or damaged thermostat. Open the lid at the back of the fountain. You should see the tank for heating the water. The general is on your two round things are respectively inserted with two strands, that is the thermostat, is generally below the one with the repair of the temperature control, features a small button, you use chopsticks next button to see if there is no good drinking machine if you still like the old son, it is certainly bad temperature. Only the replacement. Two lines of the thermostat can be short to test quality, if short on electricity, can further prove that temperature control is damaged, replace. Check to see if the fuse has been damaged. It's a black one that can be unscrewed.

The pipe is a separate one, and the colors should be different According to this model, two to three, on standby. 2. measure the resistance of the heating tube with a multimeter. If it is very low or 0, then the heating tube should be broken
