Our water supply was switched off and when it came back on again the pressure was very high for a short time. Water supply is now back to normal, but my dishwasher is leaking. Water doesn't come into the machine. When I switch the machine on it seems as if the water enters the water inlet, but then water starts leaking at the back of the machine and the drain pump in the dishwasher starts up. How can I fix it myself?
