SOURCE: F 11 error code on Whirlpool Duet - Serial Communication Error ?

I believe EVERY machine will have this F11 error eventually. Here is what fixed mine. Remove the top cover by removing the three 7mm screws on the back of the machine at the top. Slide the cover to the rear and lift off. The CCU board has 2 relays on it. They have white plastic covers. One is labeled K4 and I believe the other is K2. There are five legs on each relay soldering them to the circuit board. Remove the circuit board from the machine. It is the one you can see with the top off in the back of the machine. Unplug all the connectors. Unsolder the 2 relays...brand name Omron. With a jewelers screwdriver carefully remove the plastic cover on the K4 relay. Examine the contact points on the normally open contacts and I will guarantee they will look dull and burnt. They should be bright and shiny. You can burnish the contact points lightly and clean them with electrical contact cleaner. If you take off the cover of the 2nd relay you will see the contact points are nice and bright and shiny. Swap the 2 relays and resolder them on the circuit board. While you have the board out, take a pencil eraser and rub it on the contact points where all the connectors slide onto the board. Spray the electrical contact cleaner to wash any residue away. Carefully reinstall the circuit board and replace the top cover. Our machine has done dozens of loads since I did this with no more problems. I expect another failure at some point when the points deteriorate on the swapped relay. At that point I will try and find replacements for both relays. The K2 relay apparently has less voltage going thru the contacts and does not fail. If you feel real comfortable, you can check the "wiping" action of the points by manually operating the relay when you have it out. I adjusted mine to give a bit more wipe on both relays. I hope this helps...it worked for me!!

This is a good webpage to look at: http://maytag.custhelp.com/app/answers/detail/a_id/2885/session/L3NpZC9NTU9ZLU1Bag==/sno/0

Your error code indicates that the motor is having difficulty turning.

Is the machine brand new?

If so, it's possible that the shipping bolts haven't been removed.

Note: To remove the error display, press Pause/Off or Pause/Cancel twice.

SOURCE: elite front-load washer error code F22 then F28

This is an indication of a door latch failure and/or interconnecting wiring problem. The first step in troubleshooting the problem is to unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). This is the main "brain" of your washing machine. Sometimes these error codes are erroneous and can be easily cleared by resetting the CCU. If the error code reappears following a CCU reset, then you have a genuine problem. In addition, if the door latch remains locked following this procedure, there is a manual release you can use to open the door. Follow these steps:

1. Remove the lower panel under the door by loosening the three screws under the bottom edge on the front of the washer. HINT: If you prop up the front feet of the washer with a 2 x 4, it makes access to the screws much easier.
2. With the screws removed, the lower panel should drop down then come off. If the panel sticks, a light tap on either side will knock it loose.
3. Reach your hand up inside the washer behind the front casing on the right-hand side. This is where the door latch assembly is located.
4. At the bottom of the door latch assembly is a small pull tab. This is the manual release for the door. Pull the tab straight down and the door will come open.

If you still have the error code displayed, inspect the door latch mechanism for any broken, loose, or missing components. Next, open the top panel of the washer by removing the three screws in the rear of the washer that hold the panel in place. With the screws removed, the panel will slide back, then off. Locate the door latch on the right hand side behind the front panel. Inspect the wiring harness from the door latch to the to CCU. The CCU is located directly behind the wash tub in the top rear of the washer. Make sure all the connectors are snug and not loose or broken. In the majority of cases, a persistent error is a failed door latch. If all these preliminary checks are unsuccessful, replace the door latch. Follow these steps:

1. Unplug washer.
2. Remove the outer portion of the door bellow. This is the gray rubber boot around the door. Feel around the edge of the door bellow where it attaches to the front of the washer. You will find a wire retaining hoop in the seam between the rubber and the front case. Follow this wire hoop to the bottom of the door bellow and you will find a tension spring. Carefully, stretch this spring apart and remove the wire hoop.
3. Pull the rubber bellow from the door facing on the front of the washer being careful not to rip or tear it. Once removed, fold the rubber backwards inside the drum so you can access behind the front panel. DO NOT remove the rubber bellow from the wash tub.
4. The door latch assembly is located behind the front panel of the washer on the right hand side. Locate and remove the three screws on the washer front that hold the door latch assembly in place. The whole assembly should come free from the washer front and be held by a plastic mounting bracket and several wire connectors.
5. Carefully remove the latch assembly from the plastic mounting bracket BEFORE attempting to unplug any wires. It makes it much easier to access if you do.
6. Unplug the wire connectors using care not to break any of the wires. You may want to write them down, but I believe they will only plug into their respective slots.
7. Remove the old door latch and install the new one in the reverse order of the steps I just presented to you. Plug the wires back in first, then place the whole assembly back into the plastic mounting bracket, and then reattach to the front of the washer.
8. Now, when you get the reinstalling the rubber door boot, you may want to get the assistance of a second pair of hands as it can be difficult sometimes to manipulate the wire retainer back into place. Carefully reattach the rubber bellow to the door facing on the front of the washer first.
9. Starting at the top of the door bellow at the 12 o'clock position begin inserting the wire hoop back into the groove. Work your way around with both hands to the 4 and 8 o'clock positions. (This is where you could use those second pair of hands). While holding a slight downward tension on the wire hoop to keep it in place, pull the tension spring apart enough to snap the remaining part of the hoop into place at the bottom. Once you've completed these steps make sure the door closes and latches properly. NEVER slam a door with an electronic latch. They can break easily.


NOTE: Another method is to access behind the front panel from the top with the top panel removed. Either method works, but I have found that going through the front offers better access.

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.

SOURCE: F28 error code on Maytag front loading washer

The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) has failed.


Possible Causes

- Reversed polarity or mis-wire along with open ground switch(es).

- Communication cable from CCU (MI3) to MCU is damaged.


Procedure for reversed polarity or mis-wire

1. Clear error code.

2. Unplug washer or disconnect power.

3. Check the white wire on the RFI filter to ensure correct polarity.White wire needs to be toward front of washer.

4. Check outlet for correct polarity. To check within washer for polarity at the RFI, white to cabinet ground must be 0 volts.

5. Check that the ground switches of the toe panel and rear panel are correctly closed.

If switches are good ,replace the CCU.

I have an F28 error what is wrong


As far as I know F28 error code means - SERIAL COMMUNICATIONS ERROR/MOTOR CONTROL UNIT ERROR. Caused by either a communications problem between the Central Control Unit and Motor Control Unit, or Motor Control Unit internal failure.

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.

EPIC MODEL MHWZ600TW00...no display, no power up. Have tested outlet and electricity is fine. Would love to have an error code to help, however, without display I am lost.


diagnostic test -- the washer must be empty and the control must be in the OFF state before pressing the touch-pad sequence to start the test. 1) close the door 2) select any one key (except PAUSE/CANCEL) and follow the steps below, using the same key): a) press/hold 4 sec b) release for 4 sec c) press/hold 4 sec d) release for 4 sec e) press/hold 4 sec 3) upon release, all console LED lights will turn on for 5 sec 4) if there are any failure codes, they will be displayed in the Estimated Time Remaining display. NOTE: This program recalls the most recent failure code first. 1) press the same key to advance to the next failure code. (if the console doesn't change then the same failure code was stored multiple times.) 2) if there aren't any more failure codes all the lights on the console will turn on for 5 sec 3) next the washer begins the diagnostic test 4) to cancel out of service mode press PAUSE/CANCEL. this exits you out of the program. **Hope this helps; got it off the manual for service technicians.... most likely you'll get an F28 code (Serial Communication Error -- the communication between the central control unit (CCU) and the motor control unit (MCU) cannot be sent correctly). We are having this problem now and just replaced the CCU to a tune of around $300 ($120-$150 for CCU part & repairman labor cost + call/diagnostic cost)... it still is not working so I guess we'll replace the MCU next. If that doesn't work then we'll have to get a new washer that's not a frontload. What a nightmare; wished we had done research on frontloaders. Good luck!

Maytag MAH8700 - NP error code - Door locked and won't open


I don't know if you are aware of this, but Maytag did a recall on this washer in March 2007 where there was a risk of water leaking into the control panel and shorting out the board. You can follow this link to see if your washer was affected based on the serial number:

http://www.cpsc.gov/cpscpub/prerel/prhtml07/07135.html.

Here is a link to your user manual to see if it offers any help. The only thing I saw was to use the Cycle Selector button to unlock the door.

http://shared.whirlpoolcorp.com/assets/pdfs/literature/DC6802030B01.PDF

I found this on the Maytag site:

Is the door locked and the Add A Garment or Add Clothes light off?
If the Add A Garment or Add Clothes light is off, then the washer door will unlock after the Pause/Off or Pause/Cancel button is pressed twice. The door will not immediately unlock while the cycle is running due to a possible high-water level in the washer, high-water temperature, tumbling or spinning. It may take up to five minutes for the washer to stop spinning and draining before the door will unlock. You will hear the door click when it unlocks.

You could also try their customer service number to see if they have a script for this problem: 1-800-688-9900

The only other solution I can offer is to disassemble your washer if its that urgent and you can't get a repairman out there.

Washer starts then stops and displays f28


hello southerndav4,
Welcome,

you said, you when the unit is started in any cycle it will lock the door and then run water in for a couple of seconds. It then stops the water and unlocks and immediately locks again. There is no further action except the timer counting down until f-28 code. There is no tub rotation and the ccu was replaced.

I see you did a couple of tests and replaced the CCU!!
You did do what I would have suggested.

You may need to use hands on service this time!
rather than swapping out expensive parts blindly!


Let me know...
Huum
Please remember to leave a rating



This is the condition fo the F28 error code
SERIAL COMMUNICATION ERROR
The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

This is what you need to check and or repair

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.
