I have come across a few Hotpoint Washer/Dryers where if installed in a property with very high water pressure water floods out of the detergent dispenser after about 15 seconds of filling.
I have checked the vent hoses and cleaned the condenser checked the restrictors are fitted behind the inlet valve filters. The dispenser to tub hose is clear and raised the from of the machine slightly
The only way of stopping the machine from leaking is partially close the washing machine tap to reduce the volume of water entering the machine.
I wondered if changing the dispenser to tub hose might help but I can’t see anything wrong with it?
