Possibly - I wouldn't really know. Trying to describe the sound it is a repetitive dum-dum...dum-dum (sort of a whirry pump like noise), if you open the door it continues and is much louder and it does sound like it is coming from the filter area in the bottom middle of the dishwasher (although that is also close to the spray arm inlets)
okay, this is stuck in flood mode. for some reason you have water in the base pan underneath the dish washer. this hold the float up and the pump continues to run interrupting the cycle. you need to get the water out underneath.shut the power off at the breaker before doing this. the best way to do that is to remove the dish washer from under the counter and tip it over to the left and let the water run out. these are hard to get to (the base pan) so its easier to tip it and let the water run out,once thats done let it dry out and restore power and it should be fine.
ok - will give it a go and let you know how I get on - thanks
Thanks for your help, tipping it didn't seem to be doing much although a little bit of water came out, so I also removed the drain cover again and sucked the water up with my vax aswell. It seems to be working fine again. Thank you
