Have had this boiler for about 7 yrs the central heat side has always switched itself off now and again and I have had to reset it to get it started again. But over the last couple of years its got really bad and will switch itself off quite frequently and it gets really annoying. I have had a couple of plumbers in to look at and they say its PROBERBLY the board at a cost off between £250-£300 for parts alone if add thier labour costs I seem to be nearly into the cost of a new boiler and thats assuming they come up with no further problems. Has anybody any ideas. If it is just the board I capable of replacing this myself.
