    This is weird, customer complains of m/c pulsing mid wash, saw it for myself once, it seems the wash motor pulses ,the start neon dims then brightens as it pulses. This only seems to happen after m/c has been on for a while,any ideas?

    LOTS AND LOTS of problems with those over sized askol circulation pumps. I had a contract with CDA (before they dropped us for their own engineers after agreeing to take their extra jobs and taking on a corgi/refrigeration/general white goods engineer and buying him a brand new van to help them out with THEIR agent work… :evil:) which is a different story, repairing their CW494 whirlpool dishwashers and the amount of problems with that type of motor was massive! But I suppose thats just a drop in the ocean considering the problems with their later version of dishwasher.
