I have a gas combi Sime Super 80. I had a problem where the CH was working fine and the DHW would only kick in if the taps were fully turned. The fault looked like a DV problem. I ordered a DV and arranged for an engineer to replace it. The said engineer came and replaced the part, re-commissioned the boiler with pressure at 1.6bar, checked that the CH and DHW were working but only briefly. All appeared to be sorted so we went out for a few hours.
On return, I checked the boiler and pressure had gone up to 3.5bar and the CH would not work, I bled some radiators to get the pressure down which it did for a while but since then it has gone back up, the CH still does not work. I phoned the engineer and was shocked by his attitude, he implied the part was dodgy and that he did not like working with provided parts. Then why take the job in the first place?!?!!?!? He said everything was working fine when he left, must be something I had done!?!? He has however agreed to come and have a look but I have a gut feeling that he is going to try to squirm out of it. Can anyone confirm if a DV would cause the pressure to rise and/or the CH to not work?
I paid the engineer by cheque and hopefully he will come and fix it but I have a horrible feeling, he will not fix the problem!!!! HELP!!!!
