The noise it makes is it the drain pump that's running?
If so is it running all the time?
yes its the drain pump i think
Ok when this happens what it is will be a water leak in the base so it activates an anti flood switch in the base which keeps the pump pumping all the time and brings the light on which you see.
What you need to do to fix this is pull the dishwasher out and tip it backwards and this will allow the water to drain out from the base so you may need a towel for this part.
Once the water is it the anti flood switch will reset itself and then you can use the dishwasher as normal.
Then just see how it goes from there. Fingers crossed its just an overflow from inside but if it does it again then theres a leak in there which you need to find and fix to cure this.
If you need anymore info just get back to me.
Hi thats great it started working after doing what you sugested how would i know if it did have a leak?
That's good. If there is a leak it probberly wont last a full wash as It will do it again so if you a few washes out of it I think this will be fine.
