Hi all,
My combi boiler has two problems.
1/ The hot water won't come on unless the heating is on. Sometime with no heating on if I leave it long enough, like 15 minutes, I finally get hot water.
2/ The heating has started playing up. First I got F1 which is overheating. The saftey switch needed reseting after I bleed the system.
It then repeated this error 10 days later. I reset it again it ran for about an hour then again F1 error. Reset again run for about 4 or 5 hours then stopped.
When I went into the loft there was no F1 error and pump was working but no flame.
It then started working again an hour or so later.
Then stopped again, no error, just stopped. I checked all electrical connections connected sound, checked visually all looked ok.
In frustration I gave the side a whack, it sprung into life.
It then stops again a few hours later.
The heating temperature was 23c so frost protection isn't kicking in.
Any ideas?
As the boiler was replaced on the cheap and the system was never descaled or flushed, I'm thinking use a chemical descaler and then refill the system with inhibiter.
