Common Worcester Bosch Issues We Find

Problems we regularly diagnose and fix during Worcester Bosch services.

EA fault code

Flame detection issue — often caused by a dirty electrode or ignition lead. Usually resolved during a service.

Low boiler pressure

Common on Greenstar models. Can indicate a slow leak in the system or a failed pressure relief valve.

Diverter valve sticking

Hot water runs fine but radiators don't heat (or vice versa). The diverter valve may need cleaning or replacing.

Noisy operation

Kettling or banging sounds often point to limescale build-up on the heat exchanger, especially in hard water areas.
