Since October last year we have had a problem where the boiler goes to red light (turns off) whilst trying to heat the house. The problem was very intermittent from once a week to now at least once a day if not more. It also seems to go to red light when running the taps, for example whilst taking a shower it starts off fine then the water goes ice cold and have had to turn on the boiler again as its turned off, just this evening, the heating was running fine until I turned on the cold tap in the bathroom to brush my teeth and it turned off the boiler. On occasion we have been completely unable to get any hot water unless we have the heating running at the same time.
We had a gas safe engineer look at the boiler and told us it all looked fine, he then diagnosed that he suspected a cross leak behind the shower which was letting cold water back into the system and shutting off the boiler. I haven't been able to find any information on this online. When we moved into the flat the shower always pretty much had one temperature so a plumber suggested fitting a new temperature valve, in case cold water was flowing back into the system this way. This has been done but has not fixed the problem.
The entire flat is underfloor heated, but has anyone heard of a cross leak turning off a boiler? Or has anyone got any idea why this might be happening? Many thanks
