What is the reason why the electric water heater shows that it is burning but not heating? Electric water heater maintenance

As a regular household appliance, electric water heaters play an important role in our daily lives. It is powerful, but it can also cause some faults. For example, the electric water heater suddenly fails to heat. What is the cause? Let’s analyze the following together!

1. Check for electricity

Some power failures are invisible and only manifest themselves when you really need a device. And your hot water production equipment is not immune to electrical faults, which can be easily controlled on the electrical panel.

Find its circuit breaker and make sure it is fully raised and in the “on” position. The problem may also be a blown fuse. In this case, just replace it!

If the problem persists, check that your device is properly connected to the power supply, although there is little reason to unplug it from the power outlet.

2. Force the water heater to run

This operation sends a command to the water tank to heat the water and requires a wait of one to several hours before water can be drawn from it, depending on the power of the equipment and peak/off-peak configuration. If the water is even a little hot after that, the problem is that you are using too much water for a while.

3. control the thermostat

As a guarantee for the regulation of water temperature in the equipment, the thermostat is easily disturbed. Usually hidden under a cover, on the lower part of the device, sometimes requiring rearming. It may also require resetting the setpoint temperature to heat the water to the correct temperature again. The device may also have entered a safe state and can be restored to its original state using a screwdriver in the same area as the thermostat.

4. Descaling of hot water tank

Air and scale are the real concerns of heaters. They often block pipes or radiators, and do not have spare hot water tanks. When they are full, they lose performance and must be cleaned and descaled to solve the problem.

That’s it: turn off the power (remove the fuse or place the circuit breaker in the “off” position), turn off your general water supply faucet, turn all hot water faucets in the house to full maximum, wait until the tank is empty and turn on the tank, disconnect the thermostat and use a soft sponge to scale the bottom of the tank, clean the resistor with a soft brass wire brush, and finally dry everything with a cloth.
