I had this boiler installed about 3 years ago and have had no issues. About two weeks ago I put the heating back on and it seems to have impacted on the hot water pressure which has become very weak.
I have had two engineers out to look at it and they keep blaming the mains. I know this is not the case. Before the pressure dropped F22 came up on the box. This has now gone.
I have had the heating switched off and the pressure to a certain extent has come back, although it is still not as powerful as it was.
I switched the heating on again yesterday morning and the pressure on the hot water had gone again.
I spoke with another engineer and he mentioned a part which may be faulty (apparently a common problem with the Vailliant boilers), something about it getting hot and so it stopping the hot water pressure?? I can't get in touch with this engineer again...
I have another engineer coming out again on Thursday and am looking for any help or advice about what might be wrong. Any suggestions?
