How to repair electric water heater? Repair electric water heater strategy

Electric water heater is an indispensable electrical appliance in the home. With electric water heater, you don't have to wash your face with cold water in winter, but with the use of electric water heaters, electric water heaters often encounter various problems during use. Maintenance, the next decoration home network Xiaobian will come to introduce you how to repair the electric water heater , I hope this article can bring you some help and reference, let us look at it together!

Fault phenomenon 1: During the heating process of the water heater, there is water droplets in the small hole of the safety valve (this is a normal phenomenon)

the reason:

Since the electric water heater belongs to a closed type storage type electric water heater, in the heating or heat preservation process, the water pressure of the water heater inner tank is greater than 6Mpa, so that the one-way safety valve overflows and drops water drops.

Approach:

Close the inlet valve and adjust the mixing valve knob to a high temperature to avoid water leakage from the one-way safety valve and allow water to drip from the shower. If the mixing valve is not installed, the hot water ball valve can be opened a little, where the pressure can be drained, and the leakage of the one-way safety valve can be avoided.

Fault phenomenon 2: the water heater is used for a short time

the reason:

The first time the water heater is used (or the section is unused from the environment). Because the heating time of the water heater is short, the water temperature in the upper and lower layers is not uniform, resulting in less hot water.

Approach:

Continuous use of the water heater for more than 12 hours, so that the water temperature inside the water heater is evenly distributed.

Symptom 3: The water heater indicator is always off

the reason:

The temperature sensing surface of the thermostat has less contact with the surface of the electric heating tube flange, and the temperature controller is bad.

Approach:

Reinstall the thermostat to make the temperature sensing plane contact and replace the thermostat.

Fault phenomenon 4: When the water temperature is very low, it will enter the heat preservation state.

the reason:

The temperature of the thermostat is too low

Approach:

Replace the thermostat (the temperature needs to be increased for the tunable thermostat).

Symptom 5: The heating indicator is not lit and cannot be heated (not in the temperature state)

the reason:

The contact of the thermostat is poorly connected or disconnected, and the thermostat is blown.

Treatment method: Check and replace, replace the thermostat.

Symptom 6: The heating indicator is on but not heated.

the reason:

Poor contact or disconnection of the heating tube connector. The heating tube burned out.

Treatment method: Check and replace, replace the heating tube.

Symptom 7: Leakage during the use of the water heater (strong displacement type)

the reason:

The air pressure switch is not properly adjusted. The position of the suction nozzle is not appropriate. If the silicone tube is detached or cracked, the leaking pressure will not push the wind film. The wind pressure switch is out of order. The pulser is faulty.

Approach:

Adjust the air pressure switch to the appropriate position. Adjust the suction nozzle. Plug in or replace the silicone tube. Replace the air pressure switch. Replace the pulser.

The above is the introduction of the repair electric water heater brought to you by the decoration home network Xiaobian, I hope to bring some help to everyone, I wonder if everyone is satisfied with the introduction of Xiaobian?
