Remeha fault code E01.20
Fault code E01.20 on a Remeha boiler (including Tzerra Ace-Matic) means: Maximum flue gas temperature reached. Reset the appliance once. If the code comes back, a part is usually faulty. You can check the water pressure and settings yourself; leave work on gas-carrying parts to a certified gas engineer.
After a safety alert (gas, flue gas, combustion), reset no more than once and call in a certified gas engineer. If you smell gas, call your national gas emergency number or 112 immediately.
Cause
Fault code E01.20 on a Remeha boiler indicates: Maximum flue gas temperature reached.
Fixing fault code E01.20: step by step
- Check outside that the air intake and flue are clear (leaves, a nest, ice or snow).
- Check that the condensate trap under the appliance is filled and clean; a blocked condensate drain can make the boiler lock out.
- Reset the appliance once. If the code comes straight back, do not keep resetting it.
- If the code comes back, stop resetting: a flue problem can let carbon monoxide (CO) into the home. Call in a qualified heating engineer and make sure you have a working CO alarm.
