What should I do if the water heater is kept warm and not heated? Repair of common water heater faults
In our daily lives, water heaters play a vital role. However, after long-term use, the heating efficiency of the water heater may decrease and may even stop heating water completely. To solve this problem, it is recommended to find out the exact cause of the failure.
Common causes of water heater failures are summarized as follows:
1. Temperature controller disconnected
All electric water heaters have a temperature controller that prevents overheating. When this controller is disconnected, the electric heating coil will also be disconnected. Manually reset the temperature controller and check it with a multimeter. If the temperature controller has tripped, pressing the reset button will restore hot water flow.
2. There is a problem with the heating coil
If the heating coil is damaged, it will not be able to heat water. Use a multimeter to check whether the heating coil has electricity. If there is electricity but not heating, a new heating coil needs to be installed.
3. relay failure
If the temperature controller is not receiving power, the relay may be malfunctioning. The control panel needs to be removed to replace the relay to resolve this problem.
Common faults and maintenance of water heaters:
If leakage occurs during use of the water heater, adjust the pressure switch to the appropriate position, adjust the air inlet, insert or replace the silicone tube, replace the pressure switch, or replace the pulse.
When the heating indicator light is on but the water is not heating, the heating tube should be checked and replaced to resolve the problem.
The heating indicator light does not light up and the equipment cannot heat up. Solve this problem by checking and replacing the thermostat if necessary.
During use, the leakage protection plug will automatically trip, and the power supply will be restored after pressing the reset button. Replace with high-quality sockets. Check the copper pins of the leakage protection plug. If they look black, remove the oxide layer with fine sandpaper. If the stitches are deformed, they should be corrected, and the three copper needles should remain perpendicular to the bottom surface and should not be bent.
Water is not heated. Properly adjust the opening of the hot and cold water mixing valve. Adjust the power plug or switch to ensure good contact. Replace the electric heater or repair/replace the thermostat.
The water temperature is too high. Properly adjust the opening of the hot and cold water mixing valve. First, adjust the thermostat, then repair the contacts and replace the thermostat if necessary.
