Energy efficiency ratio water heater shows what is the general reason for the failure maintenance of e3-e3 gas water heater?

1. What is the fault code e3 of energy rate gas water heater?

The fault code E3 of gas water heater is the code of wind pressure protection. When the machine works normally, it is necessary to exhaust the smoke to the outside. When there is strong wind outside, the smoke pipe is too long and there are too many elbows. , which may lead to poor smoke exhaust in the machine, and this code appears. If it is confirmed that there is no strong wind outside, the installation specification may be a problem with the wind pressure switch.

Second, how to repair the e3 fault of energy rate gas water heater?

1. Reinsert or replace the thermal sensor pin and wiring.

2. Tighten the grounding wire to keep good contact.

3. Replace the water heater with a new battery.

4. Reduce the air pressure of the water heater to normal level.

5. Adjust the position of the pointer of the thermal sensor to keep it within the ignition range.

6. If the pulser fails, replace the pulser.

7. The solenoid valve can't be repaired and needs to be replaced.
