When such a failure occurs, the following 6 parts should be checked:

1) Check whether there is leakage between other live components and the housing. If so, remove the leakage point.

2) Check if there is a problem with the leakage protector. If so, replace the leakage protector.

3) Check whether the aging of the wire causes leakage between the phase line and the ground line. If so, you need to replace the wire.

4) Check whether there is a problem with the leakage protection plug and the thermal switch. If so, replace the thermal switch or the leakage protection plug.

5) Check whether there is leakage due to the decrease of insulation performance of the heat pipe or the heat pipe shell is burned through by water conduction. If so, replace the heating tube.

6) Check whether the bare wire touching the shell is caused by the loss of the conductor head inside the water heater or the damage of the insulation layer. If so, repair or replace it.

[Tips]

1) The heating tube and the thermal switch probe are directly thermally conductive through the metal, if the heat conduction is too fast and too high, it will cause misoperation. At this time, the treatment method is: the thermal switch probe from the bottom of the blind tube pumped about 40mm high power off, the multimeter placed in the electrical block (maximum 20MΩ), and then respectively the two meter pen and the heat pipe shell and any power terminal connected; If the cold insulation resistance is less than 5Ω, you need to replace the heat pipe.

2) If the circuit aging caused by tripping, at this time should promptly ask professional on-site maintenance, do not repair themselves, so as to avoid danger. If the trip caused by leakage, there will be a certain danger in use, and it must be repaired in time.
