My boiler has just started to make strange noises as it switches off.
The boiler generally works fine, but when it switches off, a noise comes from the control box that sounds like a relay switching on and off very fast.
This always starts at the end of the 6 minute pump over-run period and goes on for about 1 minute. There is also a similar sound when it switches on, but then it only lasts a fraction of a second.
A new circuit board was fitted in October 2003 (cost £100 from Baxi) because the ignition coil stopped working.
I'll be grateful for any suggestions
