Please can someone help. have an 8 year old whirlpool adg 7540/1 dishwasher that wont drain and the fault indicator is flashing 4 times. is the pump knackered or is there something i can try to do to fix it. i am a plumber and am fairly handy.
just want to know what are the likely causes of this, are the parts expensive and could i do it myself.
thanks
