My dishwasher will not work at all.
Investigate these four areas if your dishwasher is not working at all:
dishwasher may not be receiving any power. It is somewhat difficult to
check for power at the plug outlet because the plug for a dishwasher is
usually behind the unit. You should make sure all the circuit breakers
of your circuit breaker panel are in the correct positions, or check to
make sure no fuses of your house fuse panel are blown.
A properly functioning door switch will shut your dishwasher off when
the door is opened. A defective door switch may not allow your
dishwasher to operate at all. Examine the door switch and test it. If
it is inoperable, it will have to be replaced.
Cycle Selector Switch
It isn't very common, but it is still possible that your dishwasher's
cycle selector switch has become defective. Test the switch to
determine if it is the cause of your problem. Replace it with a new one
if it is.
Your dishwasher timer will not function if its motor is defective. And
if your timer is not functioning properly, then the dishwasher itself
will not function properly. Test your dishwasher's timer motor, and if
it is broken, you can replace either the entire timer assembly or just
the timer motor.
