My Whirlpool dishwasher is showing "Fault F4" in the display. When I press and hold the start button to reset the programme, it will start but no water is going into the dishwasher (although it sounds like it is trying to put water in) and after 3-4 minutes will stop and go back to displaying the F4 message.
What is wrong. Can I reset the machine or does it need a new part??
