hi,
I didn't want to hijack another thread so have started a new one.
I have an ecotec plus 831 that developed an f.75 fault thursday night.
I thought it was low pressure (have had low pressure before and the pressure gauge was low) so filled it up a little and switched it back on. This seemed to work but then pressure went high (as I'd poss overfilled)so I bled the lowest rad and it seemed ok. Then it came back so I looked it up and f.75 relates to poss a faulty pressure sensor which looking at other posts appears to be a common fault with this unit. It's about 2 1/2 years old now.
Anyway, was without heating most of the afternoon but arranged for an engineer to look at it. Got the address from the Valliant website of a local company.
So the guy turns up about 4pm and I mention the fault code to him but he doesn't seem to interested and I kind of leave him to it. He looked at the expansion tank and said not much air in so pumped in more air with a handheld pump and then starts it up and checks pipes etc - and pressure seems to be ok and no fault.
Eventually after an hour I ask him how he's getting on and he says that the safety valve has kicked in and the unit is discharging a little externally although both the gauge and the digital display show about 1.8 so he reckons that it might be a faulty sensor that needs replacing.
I didn't have a great deal of confidence in him initially so I asked him what he's been doing for the last hour and he replies that he's been doing basic checks. I questioned why he didn't just replace the part (I know it's a cheap part) and he said that the fault code is just a guide and he wouldn't have been able to get a part at 4pm anyway, but can come back on Monday.
At this stage I wasn't particularly happy about the time taken to diagnose this so said I would think about it over the weekend. I paid the callout but in my haste forgot to ask for a job sheet.
I'm sorry for the long post/rant but would appreciate any thoughts as to whether I'm over-reacting or should I have expected better service? Is what the engineer did normal practice? I personally feel that he could have got a part (I had mentioned the fault code to the callhandler) and then tested for other problems. The fault has now returned and I'm now potentially without heating for the whole weekend.
I'm tempted to complain to vaillaint about this and also to the company as I feel it's been poor service. As I mentioned I don't have a job sheet and have paid by chq. Should I ask for a refund?
In particular if anyone in the trade could answer that would be great.
Many Thanks
