Hi all

My Bosch dishwasher is playing up big time.

In operation it is making a hooting noise.
This seems to be occurring when the main pump is running rather
than the drain pump.
Also there is an under tray that is collecting small amounts of
water but this is enough to activate the drain pump
constantly.
Finally, the rcd tripped recently although I cannot be sure that
was down to the dishwasher.

Any ideas on the problem here please?

Thanks


Phil


My first guess would be a seal failure in the main pump, allowing water
to get into its bearings - and possibly its electrics. That could
explain all of your symptoms.
