The sudden tripping of a water heater under normal heating is generally caused by the following 5 reasons:

Reason 1: The heating tube and temperature sensitive switch probe conduct heat directly through the metal. If the heat conduction is too fast or too high, it will cause misoperation. Solution: Raise the temperature sensitive switch probe by about 40mm from the bottom of the blind tube and cut off the power. Set the multimeter to a maximum resistance level of 7M Ω; Then connect the two probes to the outer shell of the heating tube and any of its power supply terminals. If the cold insulation resistance is less than 7M Ω, the heating tube needs to be replaced.

Reason 2: The insulation performance of the heating tube decreases (usually only appears after a period of use), and its insulation resistance value is unstable. When the leakage current exceeds a certain value, the leakage protection plug will immediately act to handle it. Solution: Check and eliminate or replace the heating tube.

Reason 3: Leakage treatment between other charged components and the casing. Solution: Check and eliminate or replace components.

Reason 4: Poor contact between the leakage protection plug and the low-quality socket resulted in misoperation due to overheating. Solution: Replace the socket.

Reason 5: Either the splash protection plug or the temperature sensitive switch has malfunctioned. Solution: Replace the temperature sensitive switch or leakage protection plug.

If the voltage carrying capacity is not too high, the reason for the water heater heating normally but suddenly tripping is generally caused by these 5 reasons. If you are not very familiar with the water heater or its operation and circuit, you must ask a professional repairman for repair to avoid accidents.
