Swin,
A few questions before we get involved.
Does the machine fill with water ?
or is there a buzzing noise.
Does the float (in the left front corner of the tub bottom) move up and down freely,and do you hear a click noise when you lift up on it slowly ?
Did you recently have any plumbing or disposal serviced, or cabinet work done, or the dishwasher removed ?
Your drain hose may have dropped down below the tub level,the disposal or drain line could be restricted or clogged and causing a syphon effect.
Does the control panel program and run the cycle selected, as it always has ?
Does the control reach the end of the cycle and shuts off on it's own ?
Something you may want to try :
Select any standard wash cycle,
Let the unit fill and the motor run for 5 minutes,
Unlatch the door catch, wait 10 to 15 seconds, then open the door,
The water level in the bottom of the tub, should be in contact with the bottom portion of the heater element,if we've got the proper water supply.
As you can see, we want to eliminate some of the more common problems,before we start tearing into major components and replacing expensive parts.
A water fill problem, can be mis interpretted as a bad pump or control.
Let us know what you find,
:) :) :)
