    My Maytag 4000 series washer displayed error code F28 and it would not function. I unplugged the washer from the electrical wall outlet for approximately two minutes,which allowed the machine to reset itself. I plugged the machine back into the electrical outlet and it returned to operating properly.

I have a Maytag 9000. It gave me a F28 error code. How do I get the door open? What is wrong with this machine?

That's an error caused by the ccu (central computer unit) and the mau (motor control unit) not communicating properly. To get the machine open there should be some screws that hold the bottom panel. Remove those screws and reach up inside the machine (usually to the right) and feel for the door lock unit. There should be a small plastic tab you can pull and that will release the door. In my experience the f28 code can be caused by a clogged or malfunctioning pump. There is a strainer that can be unscrewed and there is usually a blockage in the strainer. If there's no blockage you need to make sure that the impeller of the pump is clear of anything. If the pump is ok you would need to replace the mcu

My maytag has error f 28

F28 is a communications fault between control boards. Before throwing money at it, check all wire harness connections. Make sure they are clean and tight. Check for oxidation on the gold terminals. Remove the connectors and put them back on 4-5 times to clean the terminals. Recheck the machine operation.

Help! How to fix F28 error on Maytag 4000 series Model MHWE400WW01?

I went through this some time ago with my whirlpool duet washer. I had the service man come out after I replaced the mcu and still did not work. He told me that he had no way to check for sure that it was the ccu but said he thinks that I should replace it so I did and it solved the problem.. I still don't understand why he could not tell me for sure that the ccu was the problem because it cost a lot to order it.

Whirlpool f28 error code and door lock light

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 a link to the CCU.
Here is a link to the MCU.

I have a maytag 4000 series and im getting a code F28 and i dont have a manual ?? can you help

Hi from retired Englishman in SW France,
I'm cheating a bit here because I do not have the decode for 'F28' but-
How to obtain a manual-
You will need to type into your search engine/web browser '(make) washer manual' and you should be presented with a number of sources from which you can either download for free or have to pay a nominal amount. During the process you will be asked for the actual model number!
You could also try the manufacturer's web site direct.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!
