The customer reports that this dishwasher is not coming on and no lights are displayed. They have cut power at the breaker for 30 minutes and cut it back on with no change. First question is if I verify power to terminal WH3 would that verify the main PCB is bad? Second, if no power is present at WH-3 the noise filter is bad (assuming power is present at the power connections)? Lastly, if the noise filter is bad, and I bypass it, should the unit operate?

Also check for loose or burnt connections at the wire nuts where the dishwasher wiring connects to the house wiring inside the junction box in the bottom of the dishwasher.

Yes---as Scott mentioned---check the power at the electrical/junction box to confirm power from the home/house circuit breaker.

Inspect the connections/wire caps (not loose or burnt).

 

If the power and wiring are "good"---pull off the *pink* plug from the Noise Filter---and test for voltage at the Noise Filter (not from the pink plug).

 

If "good" (110-120 volts at the Noise Filter)---the Main Board has failed.

 

If *no* power is at the Noise Filter---bypass the Noise Filter by "jumper-ing" the *white* and *pink* plugs.

 

Test Control Panel functions.

 

If the Control Panel "wakes up"---replace only the Noise Filter.

 

If the Control Panel remains "dead"---replace the Noise Filter and the Main Board.

 

Post the SERIAL NUMBER---this model has a *lot* of service bulletins and there's other service-related information to be aware of.


To eliminate:

Musty odor

L-O-N-G cycle times

Dingy/yellowing whites

Suds error message

Slow spin speeds

Intermittent water leaks (from rear of washer)

And other annoying symptoms which vary brand-to brand.

Read below:

The *correct* amount of HE (High Efficiency) detergent that should be used in any front load or agitatorless top load washer with tub sizes 3.0 cu ft and larger is as follows:

HE: (2) Tablespoons Per Wash Load

HE 2X: (1) Tablespoon

HE 3X: (1) Teaspoon

Perform a TUB CLEAN CYCLE every (4) months.

Use: "Tide Washing Machine Cleaner"

Thanks for the replies. I confirmed power at the junction box with no corrosion. No power was coming from the noise filter. After bypassing the filter, the unit did not wake up. The customer decided to replace the dishwasher. Thanks for all of the help.
