Default Kenmore Dishwasher Troubleshooting assistance

Hi!

The problem I am having is that the dishwasher will not spray the water
around the inside. It will fill (although it will not fill enough to
cover the filiment anymore), it will drain, it will heat up but it will
not throw the water around inside and therefore will not complete a
cycle.


How is your water pressure? Has it changed recently?

Many dishwashers have a floating limit switch that cuts off the water when
the water pushes the float up. You should be able to find this fairly easily
and test it by moving it up and down. After being sure power is
disconnected, you should be able to test the switch with a volt-ohm meter
set to the ohms resistance scale and hooked to the terminals of the switch.

Are the water feed/drain hoses cracked, kinked or blocked?

It is also possible that your dishwasher is shutting down before the water
fill has completed because of the problem you mention below with the motor.

After I turned the sucker back off, I
felt the motor and it was almost hot enough to burn my
hand.....hmmm...what do you think??????? How can I test it? If it is
the motor, it sounds like it is getting electricity to it but maybe it
is functionally broken....i dont know....


First off, BE CAREFUL. If you elect to work on this dishwasher yourself,
bear in mind that you'll be working on an electrical motor that is working
in close proximity to water. If something starts leaking or spilling water
on around the motor, just stop, disconnect power and wait until things dry
before trying again.

That said...

Is the motor in any way jammed or stuck? Can you get to the motor shaft and
turn it?

If the motor shaft will turn, then you might have a bad motor start winding,
start switch or connection causing problems. The motor could also simply
have a shorted winding. Look around for any loose, disconnected or burned
wiring connections.

If the motor shaft won't turn, or seems to be very stiff, you'll have to
figure out why this is.

Pump seals can also go bad on a dishwasher. When this happens, the motor
usually takes a bath and burns up. (I've seen this happen, and it usually
smells terrible when it does.)

If you can connect the motor to power and safely manage to turn the shaft
while it is supposed to be running, what happens? If the motor starts, then
you've most likely got a bad start switch or winding.
