I have one of the above combi boilers, installed in 1999. CH side works fine, but when using the shower the water goes cold after 2/3 minutes as the burner cuts out. It always reignites after about 30 seconds, is OK for a couple of minutes more and then goes cold again. The water pressure is not affected, it's just that there's no constant hot water.
Wife is not happy with hot/cold showers...
I recall there was a similar problem about 5 years ago and the PCB/Control Box was replaced (part no 6210203-Blue Box). Is it likely that this has failed again? If so, is there a known problem with these, as a new board every 5 years at £90 plus fitting is a bit steep...
