Whirlpool Dishwasher – ADP 7966

Hi

My dishwasher stoped with an error code F3 (something about the heating system)

After doing the 10 sec on/off reset i have run several programmes

the system fills in the bottom with water

if its on a hot run the unit fills with steam (as per normal)

when u cancel/finish a programme the unit drains all the water from the bottom

i have checked the filters and they seam clean

no matter what programme you run no error codes are generated

When you run any programme you can hear it filling with water, the problem apears to be that no water is getting sprayed out of the arms, the tablet compartment is open with half the tablet inside and bits of tablet all down the front. No sound of water whosing can be heard when the programmes running just a humming noise.

I read in one of the posts on this forum that sometimes a circulating pump can get blocked, does this sound like my problem, if so are there any diagrams as to how to get to the pump?

Thanks
