Re: Whirlpool AWM043 pump running constantly
most likely the main board is faulty.
most boards you switches called Triacs to control small electrical items like valves and pumps. in your case the pump one has probably failed. To replace it you would have to understand electronics and be able to solder small components
whirlpools answer would be to change the board but some of the engineers on here may be able to repair it
alternativeley there are 2 firms who may be able to check and repair it
