For the F28 error code:
First, check the wiring harness connections to the MCU, the Motor, and the CCU. Make sure all the connections are tight and there are no ground wires off. Then check the connections of the CCU board within the housing.

If the wiring connections are fine then It would be a good idea to order both, as both components have been problematic for the error code F28.


Here is the CCU to order.

Here is the MCU to order.

SOURCE: Whirlpool Duet Sport Front loading washer and dryer with error code

An easy Fix. Take off the kick panel, 3 screws 1/4 inch. Make sure you have a shop vac ready or a lot of towels as there will be some water. Always disconnect power to washer and dryer, and turn off water to washer. Your filter most likely is clogged with change, screws, lint, and other household stuff that we leave in our pockets! Unscrew the cap on the filter, easy to find, since you have the kick panel off! Take everything out of the filter. Take your shop vac and **** out remaining stuff in hose. Also, **** up any water that has leaked in and around the washer. Screw the cap back on hand tight, put the kick panel back on, turn your water back on, plug it in and there you go! Maybe takes an hour and saves you a repair bill. If you are not comfortable with this procedure then call a maintenance person that is qualified. 775f844.jpg

SOURCE: Problem with F21 code on whirlpool duet sport

i had the same problem. take the bottom cover off of the front of the washer. on the right you will see a round white screw off cover, it is very tight, it unscrews counter clock-wise. pull this out and see if there is any debris in it. if you look into the hole on the right side there is a hole about 1 inch round, this is the pump opening. you may have to take the gray drain hose off of the back of the pump housing and feel if anything is stuck in there, in my case there was a penny stuck side ways blocking the flow of water. after i took it out the washer has been running great again. this is obviously a design flaw, that something that large could manage to get that far, lucky for me it didn't damage the pump impeller. hope this helps. this should take care of the SD and the F21 error codes.

SOURCE: have a whirlpool duet sport getting a f28 error

F28 is a serial bus error from the CCU (Central Control Unit) to the MCU (Motor Control Unit).

All you need is some Electronics contact cleaner spray and a 1/4 inch socket to remove the top of the machine and the back of the machine.
The CCU is the computer looking box at the top front right hand corner.
Find connector M13, (has red marking on it and only 3 wires) disconnect it by pushing the retainer tab back and pulling gently on the connector.
Spray the contacts of the connector and computer with connector cleaner.
Then re-assemble connector.
The MCU is in the back lower left corner.
Find the connector with 3 wires and red mark, and remove this connector in the same way you did the other, spray it and re-install.
Put the back and top back on.

Whirlpool Duet Sport Model WFW8300SW0 basket won't


The following list of codes indicates an electronics communication problem with the washer: - Duet HT washer - F01, F03, F06, F11, F23, F24, F27, F28, F29, F30, F31, F32, F35, F42, F61, F62, F63, F64, F65, F70, F71, and F99

If Pause/Cancel does not work:
  1. Unplug washer or disconnect power for one minute.
  2. Plug in washer or reconnect power.
  3. Re-select the cycle and press Start.
NOTE: If the error remains on the display, call for service.

I would first replace the door latch/lock assembly, a number of users have and it fixed the F-11 error code completely. Its the cheapest part for this problem.

Hope helps.

Kenmore H2 PLUS reads F--28 code what does this mean?


The error code F28 means one or both of these parts are bad.
Motor Control Unit (8540135)
Microcomputer Machine Control Unit (8540788)
It would be a good idea to order both, as both components have been problematic for error code F28

If you find either the MCU or the CCU(Microcomputer Machine Control Unit) fixed it.

Here's the online repair manual for your
Whirlpool Duet Sport, but its identical to your HE2.
Give it time to download.
On page# 4-20 it shows how to access your MCU.

Error code Sd (or 5d)


It means Suds Lock(Overdose of Detergent Detected During The Wash Cycle).If suds are detected continuously by the pressure switch during the drain or spin phases,the washer will fill 4 litres of water and during 5 minutes the unit will rest without tumbling,the water will be drained and it will try to spin or drain again.

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.

New Whirlpool Duet Washer(WFW9300VU02) F28 error


You can call whirlpool for service but the tech sheet f28 has a communication problem from you computer to the motor..

The communication between the Central Control Unit (CCU) and
the Motor Control Unit (MCU) cannot be sent correctly.

Possible Causes/Procedure
1. Unplug washer or disconnect power.
2. Check wire harness connections to the MCU, the motor, and
Central Control Unit (CCU).
Check connections of the CCU board within the housing.
Make sure all grounding switches are engaged.
3. Check the drive system for any worn or failed components.
4. Plug in washer or reconnect power.
5. Verify CCU operation by running a Diagnostic Test or any
cycle.
6. Check the MCU by looking for operations of the drive motor.
7. Check the drive motor for powered rotations.
8. Check that the serial harness at the MCU is not mounted
upside down. The wires should be to the left when facing
the MCU connectors.
