My 10 year old (but regularly serviced) boiler has developed a problem in that it overheats when we are using the shower causing the overheating reset switch to pop up.
Once the overheating switch is pressed down the boiler fires up and continues on (usually for around 4-5 minutes however sometimes longer).
I have had a heating engineer here and he replaced the pump however the problem remained. He came back and spent ages on the phone to Worcester but still nothing (apart from try to clean the shower head). I did this (it was already clean with no buildup) but the problem remains.
If anyone had any other ideas I would be really grateful!!
