When this happens what it will be is water has leaked into the base of the dishwasher and has activated th flood switch which keeps the pump running all the time.
What you need to do to fix this is pull the dishwasher out from under the unit and lie it on its back.
This will allow the water to drain from the base so you may need a towel for this part.
Then stand it upright and retry the dishwasher and fingers crossed this will get it working again from there.
Try that and see what happens and let me know.
ok, will give it a go. thank you
No worries let me know how it goes.
