Question about Dishwashers

Frequently failing TCO

Whirlpool dish washer WGU1500XTKQ0. TCO has failed several times. Operation seems normal: No excessive current-drain. No excessive temperature. When it runs, it runs well. What's happening?

    I have the same problem. I have changed the TCO three times and has just failed again. I have looked at all possibilities of hot moist air getting in behind the panel and could find nothing out of the ordinary. I measured the current draw through the entire cycle, it is within the rated specs.
    Is there anything else that can blow the TCO?

The TCO comes with a plastic sheet to protect it from the hot moist air. Was that installed on the new TCO? Somehow moist air is getting into the console.

The dishwasher is not draining properly and there seems to be lots of suds although the detergent packet was not used during the normal washing cycle.


If your dishwasher is connected to a garbage disposal and not used frequently and you
hand wash dishes on the disposal side, the soap that is used for hand washing dishes
accumulates in the dishwasher when you pull the stopper. This soap sudses excessively in
the dishwasher when it is run. This happens quite frequently in the apartments I service.
I have to put in several pans of water and turn the timer till it pumps out several times.

Also, make sure the disposal is working properly or the dishwasher will not drain and dish
water will back up into the dishwasher. There is usually a 5/16 allen socket to free
the disposal located under it in the very center of the disposal as well as a small red sqare
reset button once the unit is freed up. Make sure switch is off at wall before attempting
service.
hope this helps.

Sud: Suds lock (overdose of detergent detected during wash cycle)
The motor control unit senses a suds lock condition by analyzing the
current draw on the drive motor. If "Sud" is displayed a potential Suds
Lock is detected. This may signify a bad pump, an extra heavy load,
excessive detergent, or excessive suds.
Possible causes/procedure:
If too much detergent was used:
-Run the unit through a Rinse/Spin cycle.
-Run a Normal cycle without adding any detergent.
This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged
or kinked.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the drain pump,
pressure switch, and Central Control Unit (CCU).
4. Check/clean drain pump filter of foreign objects.
5. Plug in washer or reconnect power.
6. Check drain pump.
7. Check the pressure switch.
8. Verify CCU operation by running a Diagnostic test or any
cycle.themobilian_756.jpg

Use your tech sheet for diagnostics it is behind that panel the Handy Hippy showed you how to take loose (see above link) Use this MANUAL for Duet sport as a guide for repairs

Duet Washer will not spin water out


Hello, The most common cause of the 'sud' alarm is too much detergent, or the detergent that is being used is creating too much suds. It works and alarms off of the motor current draw. The causes and cures listed below are pretty much in order of their commonality; try the first item before the second one, etc. If you can pin the fault on the detergent, try using the least amount of detergent that you can while still getting your clothes clean. With a HE washer, more isn't always better. Read on:

The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If “Sud” is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Potential Causes

• Check Drain Pump
• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
• Check the Pressure Switch

Replace failed component.

Hope that this helps. Try the empty loads first to clear the detergent. This is the easiest fix.

Washer stopping mid-cycle with no error


Remove the 3 screws at the bottom of the front panel under the washer door. Your filter door will be light brown. If you find a hose there it is to drain out excess water (water that could not be drained by your pump) After you have drained, unscrew the cap and remove all the junk inside. Have a large plastic bag to catch junk and water. Refit carefully after cleaning out. If not solved, something shd be blocking your pump, check this out. F-21 filter blocked.

Will not go pass the wash cycle to spin or drain


There is at least one safety switch activated by the lid.
Depending on machine construction, these are somewhat exposed to water incursion that eventually causes them to fail.
The slamming of the lid is causing the failing switch to make enough contact to allow it to spin.

If you are lucky (I don't know your machine), these may be located toward the rear of the housing where they can be fairly easily replaced.
