Hi All,
Can we please have some advice on our problem? I have tried to read as much as i can on here before i made my first post.
We currently have boiler insurance with Domestic and General.
Recently our shower started to go cold and then hot again around 2 minutes a time. I noticed by looking at the boiler that it was cutting out, flashing and then re-igniting. This has gradually got worse and worse. Now on setting 6/10 water temp it cant run for over 10secs! The Radiators seem to be working perfectly...
We called out D&G for a repair and they sent out a guy who`s analsys was that the system was sludged up and the heat exchanger blocked. He took off the heat exchanger and cleaned it out with Cilit Bang!
When he had done this he refitted it and it was exactly the same. He said that it must be blocked and we are not covered under our policy.
He recommended a chemical flush that would cost around £320 and they cannot do anything else for us until we get this done....
After reading on this forum we took off the heat exchanger and used a chemical cleaner (small bottle S.Acid) and after it had turned blue, when we poured out the used liquid there was a medium amount of black sludge/bits in the bowl. We then repeated it again and this time there was hardly anything. We then hosed it and then cleaned it again with Fernox DS3 Scale Remover, this again didnt bring out any other dirt.
So.. we refitted it back after this mammoth clean, crossed our fingers and guess what..... everything is the same!!!! cuts off straight away
Even If it was cleaned out even slightly should it atleast last a bit longer before cutting out? The water DOES get very hot when its on the hot setting, would that mean that the heat exchanger IS working and not blocked?
Tomorrow we are having a temperature sensor delivered, do you think we are on the wrong path? Is there anything else we can please check
Boiler: Alpha CB28
When set to 10/10 water heat - lasts 28sec before going out and relighting
When set to 1/10 water heat - lasts about 5 secs
Heating Seems to be fine
Just before it cuts out, maybe 5secs before, the water goes cooler and then it cuts out.
We are a bit annoyed that we are having to pay for parts ourself when we pay for cover, but they are basically holding us to ransom untill we buy a chemical flush!!
Thankyou in advance to all !
