Worcester Bosch EA: No flame detected (EA / 227)
Safety related: do not keep resettingWhat it means
The boiler tried to ignite and did not detect a flame. Common causes: gas supply issue, frozen condensate pipe, faulty electrode or gas valve.
Safe things to try first
- Check other gas appliances work and the meter is on credit.
- Check the white condensate pipe outside is not frozen.
- Reset the boiler once. If it locks out again, stop.
When to call an engineer
Repeated EA lockouts need a Gas Safe engineer to test the gas valve, electrode and flue. Do not keep resetting.
Never remove the boiler cover or work on gas components yourself. It is illegal unless you are Gas Safe registered, and it will void your warranty.
