perplexed.......
I have a Sime Friendly Format 80 e.
Water, both heating and hot water supply, will only run for a given period before the boiler knocks off; It will sound almost as if it is runnig, but when you check the glass there is no burner flame. The running time can last from ten minutes to half an hour sometimes, then it runs cold. The boiler then has to be turned off for a few seconds, then re started. Can anyone help?
