When such a failure occurs, the following 4 parts should be checked:
1) Check whether the water mixing valve outlet pipe is blocked. Can touch the water mixing valve outlet pipe and heating plate position for heat, heating time is too short, screw out the water pipe for hot water.
2) Check that the plug of the electric heat pipe connection falls off and is disconnected, and use a multimeter to measure whether the connection line is on.
3) Check whether the electric heat pipe has 220V working voltage (use the multimeter AC250V stop to measure whether the two terminals of the electric heat pipe and the connection line have 220V working voltage).
4) Check whether the heating wire of the electric heat pipe is burned off (you can use a multimeter to detect the electric heat pipe to judge).
