Can anybody help me with a Worcester-Bosch junior 28i condensing boiler which I have been having problems with for 6 months...as I’m pulling my hair out!!!
The pressure in the system after being on for 20 minutes rises from 1.0bar to 3.5bar and then the water pressure fires the prv. When you turn off the heating demand the pressure drops to 0.5bar or less, so you top it up and the whole scenario plays out again. This eventually broke the last prv (because of dirt on the seat and it wouldn’t reclose)
Here’s what has been done so far:
1.The pressure vessel has been checked by an engineer. It is not broken and has the correct pressure every time it’s been checked.
2.As I say the pressure release valve has been replaced last week after the previous one eventually broke due to releasing water
3.There are NO leaks anywhere in the system
4.The system has been checked and serviced regularly and two engineers’ from different companies seem at a loss to the problem
Has anybody here got any idea’s???
ANY help would be most appreciated!
