My CH system has recently developed a problem. When either the hot water or heating is switched on, the boiler (Baxi Solo 60PF) runs for about 10 minutes and then cuts out. It immediately re-lights and then immediately cuts out. This keeps repeating. I\\\'ve had BG out and the guy replaced the main circuit board and the overheat sensor. This has not cured the problem. The pump appears to be OK, so the guy concluded that the problem was due to sludge and scale in the system and recommended a Power Flush. The boiler is 18 months old. Could my problem be due to sludge and scale or could there be another explanation?
Any help much appreciated.
