e2 is an error code indicating that the water heater is faulty.
1. Possible reasons:
1, the fan itself is faulty, can not operate.
2, the wind pressure switch or flue is blocked.
3, fan circuit problems. Gas water heaters generally indicate that dry burning overheating, dry burning without water, water flow detection of low pressure, filter blocked.
2. The following checks should be carried out gradually:
1. The air inlet is blocked by foreign matter such as raw material belt, resulting in reduced air intake.
2. The smoke pipe anti-backwind baffle is stuck, resulting in poor smoke discharge.
3. After the fan or fan starting capacitor is damaged, the wind speed does not turn, resulting in the flame being extinguished.
4. The condenser drainage hole of the condensing model is blocked, resulting in condensation water stored in the condenser, and the flue gas cannot be discharged, resulting in E2 failure.
5, the fourth or fifth nozzle on the right side of the distributor is blocked, resulting in fire conversion, the flame is extinguished to report E2 failure.
If E2 is displayed, then the remaining amount of natural gas is not enough, it is recommended that you refill the natural gas.
