I have just repaired my 18 month old WD420P. It had indicated the F03 fault and I had to replace the Control Board.
About 11 months after purchase the machine it gave out three loud pops and a little smoke appeared from the top ( think it was on a wash cycle)–fuse had also blown in plug. Having trained in electronics it sounded like capacitors exploding?
I had the Hotpoint man round, as it was still just under warranty, but he could not find any problems and I don’t think he actually believed me!
My problem is could there be a faulty component that will cause short life expectancy of the control board?
Has anyone experienced this problem?
