OK Thanks for your help.
I have just turned it on again and it starts OK but then when it goes to draw in the water to start the initial wash it just cuts out and buzzes. I don't think any water is getting through.
I will take it out and see!
Our dishwasher starts a cycle but after a few minutes it stops and just buzzers. If left buzzing it makes the electric trip.
What could it be? Could it be the pump?
Thanks
