Whirlpool 4501/5 Fault

[Wistow]

Hi all

I have a whirlpool 4501/5 dish washer which is no longer working. The green power light flashes 4 time pauses and then 4 flashes again.

Having searched I thought this was a drain problem, there is no water in the machine and if I add water it is pumped out quickly, the pump runs for about 5 minutes after the water has gone.

Does this mean I have identified the wrong code?

What else might the problem be?

Thanks for your help

Draining Failure. If it's draining ok then the pressure switch is stuck, full of gunk or faulty.

I have followed the instructions on another thread and cleaned the pressure switch, pump still runs for about 5 mins, stops and light flashes in bursts or 4.

Can anyone help?

Thanks Graham
