What to do if my Airthereal Heater is not heating at all and the digital display doesn't light up?
If your Airthereal Heater isn't heating and the digital display is off, it could be due to: * No power or incorrect wiring: Make sure the breakers at the main electrical panel are ON. You may have a faulty breaker or the unit may be wired incorrectly. * A damaged screen or poor screen connection: Replace the screen or reconnect the wire.
What does E2 error mean on my Airthereal Heater?
The E2 error code on your Airthereal Heater (accompanied by 5 beeps) indicates that the temperature exceeds 149°F/ 65°C. This is a high-temperature warning, not a malfunction. To resolve this: * Select a lower power level or turn down the temperature. * Increase the water flow.
What does E5 error mean on my Airthereal Heater?
The E5 error code on your Airthereal Heater (accompanied by 5 beeps) indicates no over-zero signal. This can be due to low home voltage or abnormal grid input voltage. To address this: * Check that the voltage meets the installation requirements. * Ensure there is no interference from high-power equipment nearby.
How to fix leakage in the joint of inlet and outlet pipe of Airthereal EVT-18K Heater?
If you notice leakage in the joint of the inlet and outlet pipe of your Airthereal Heater, it could be due to: * Poor connection of the inlet and outlet pipe: Reconnect the pipe. * Damaged rubber washer: Replace the washer.
What does E1 error mean on my Airthereal Heater?
The E1 error on your Airthereal Heater (accompanied by 5 beeps) indicates a leakage of electricity. Stop using the water heater and let a professional pinpoint the leaking parts.
Why is the water pressure less and less in my Airthereal EVT-18K?
If the water pressure in your Airthereal Heater is decreasing, it may be because the inlet filter or shower is blocked by water impurities. To resolve this, remove the inlet pipe and clean the inlet filter/shower.
Why is the water temperature unstable in my Airthereal Heater?
Unstable water temperature in your Airthereal Heater might be caused by unstable voltage or water pressure. The solution is to wait until the voltage water pressure is back to normal.
What does E3 error mean on my Airthereal EVT-18K?
The E3 error code on your Airthereal Heater (accompanied by 5 beeps) indicates a failure of the water inlet temperature sensor. Check whether the water inlet temperature sensor terminal is effectively plugged into the main board.
What does E4 error mean on my Airthereal Heater?
The E4 error code on your Airthereal Heater (accompanied by 5 beeps) indicates a failure of the water outlet temperature sensor. Check whether the water outlet temperature sensor terminal is effectively plugged into the main board.
Why is my Airthereal EVT-18K water not hot enough?
There are several reasons why your Airthereal Heater might not be heating water to the desired temperature: * The user temperature setting might be too low. Try turning up the temperature setting on the unit. * The water flow rate might be too high. Depending on your incoming water temperature and the power output of your model, your water flow rate may exceed the physical heating capacity of your water heater. Try turning down the water flow. * The voltage may be less than 240 volts. The set voltage of the water heater is 240v. When the voltage used is lower than 240v, the water heater will generate less heating power. It would require a larger power model (when the voltage cannot be changed). * You might be mixing too much cold water. You do not need to mix as much cold water wi...
