Fitted a new Detergent Dispenser yesterday and when switching the power on, the solenoid switch either makes a loud humming sound or vibrates loudly, any ideas?
Sorry, only now realising you were refering to a dishwasher,not a washing machine..
Never come across that problem, hopefully someone on here will help you out.
The dispenser didn`t release the tablet during the cycle, I checked various forums who suggested a new dispenser was needed as the solenoid had failed. The connections only fit one way and it seemed straight forward until I powered it up? Also when I put the old dispenser back in it worked fine.
