Re: Whirlpool ADG 7550 dishwasher keeps beeping
6 flashes is a filling fault so if the supply tap is turned on ok then the pcb isn’t registering the fact that water is coming in.
The usual cause for that is poor connections on the flow meter, situated at the bottom of the metering tank on the LHS. Disconnect the small plug from it’s pcb (carefully as it is not very robust) squeeze it in your fingers to tighten the grip of the contacts then clean the tracks where it connects either with a pencil rubber or some very fine emery. Reconnect then let us know the outcome?
