Analysis and Treatment of Common Faults of Electric Water Heater

1、 Installation is not standardized
1. Socket failure:
A. No ground wire; B. The plug is loose; C. Unreasonable socket location;
2. Failure to install a safety valve may cause backflow, dry burning, or damage to the inner liner (the dry burning pressure rises quickly without the safety valve);
3. The inlet and outlet pipes are installed reversely, and the water is not fully filled, resulting in dry burning;
4. The water mixing valve is not equipped with a sealing ring, and the safety valve is not wrapped with a raw material belt (for safety valves with a straight through structure), resulting in water leakage.
2、 Leakage protection power line trip
1. Zero connection protection: the water heater is grounded through steel bars or other means, resulting in electrification of the ground wire;
2. Prevent damage to the electric switch;
3. Electric leakage from heating pipes or other electrical components.
3、 Water leakage at the relief port of the safety valve
1. First, open the water outlet valve and close the water inlet valve. If the water leakage continues, it indicates that the safety valve has been damaged. If the water leakage stops, it indicates other reasons;
2. Close the outlet valve and open the inlet valve. If there is water leakage, it indicates that the water pressure is too high or the safety valve is blocked by impurities.
