Question about Kenmore 3.8 cu. ft. HE4t Front Load Washer

Kenmore He4t door lock error

I have been receiveing the door lock error for some time. I usually take off the top panel and remove the wire connector that leads from the door sensors to the main computer and then put it back on and that takes care of the problem. The error has been happening more and more. Do you think replacing the main computer board will solve the issue or might the problem be with the door sensor?
Thanks

    I have the same problem with my He4t. I can hear a clicking noise as it tries to lock. It doesn't seem to be the actual locking mechanism but rather a problem in the electronics. Glad to hear drice12's temp fix and will try that this evening but I would also like to hear of a permanent fix.

No...the Main Computer (or CCU) is much more expensive than replacing the door latch. "Fdl" or "Fdu" are door latch errors and usually means the latch requires replacement. The following link explains how:

This is a very simple repair if you follow the steps provided. A replacment latch can be found at searspartsdirect.com or repairclinic.com. Just type in your complete model number in the search menu. If you require further assistance, please let me know. I hope this helps you.

PS This does not mean that the CCU still may not have a fault. Its just much easier and less expensive to replace the latch first. More commonly, the latch is the culprit.

I have a Kenmore Elite HE4t and the error code "F06" is flashing. The washer aggatates and drains but won't spin.Also the door locks and unlocks at different times during cycles. I located the error code...


The error is an indication a motor speed problem. You will need to check the following:

- Check the wiring harness. Verify all connections between the Drive Motor, Motor Control Unit (MCU), and Central Control Unit (CCU).

NOTE: The MCU is a circuit board located in the vicinity of the Drive Motor on the bottom rear of the washer. To access the MCU, you will need to remove the back panel of the washer.

NOTE: The CCU is the main computer for the washer and is located behind the wash tub. You will need to remove the top panel to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top in place. Once the screws are removed, the top panel will slide back, then lift off.

- Check the Drive Motor. Perform a continuity check of the Drive Motor windings. Remove the connector plug and check across pins 1 to 2, 2 to 3, and 1 to 3. All readings should be approximately 6 ohms. HINT: You can also take this reading by removing connector 2 from the MCU and measuring across pins 1, 2 and 3. If the readings are good, this will also prove the wiring and connector good.

- Check the MCU. The connectors are numbered 1 to 3 (L to R). That is, with the MCU installed, connector 1 is on the bottom, followed by 2 in the middle, and 3 on top.

Connector 1 - is the serial communications link between the MCU and CCU and has three wires. At the opposite end, this will be the 2nd connector from the rear on the left-hand side of the CCU.
Connector 2 - is the link between the MCU and the Drive Motor. Pins 1, 2, and 3 on this connector are the Drive Motor windings. Pins 4 and 5 are for the tachometer.
Connector 3 - is the primary power connector. Pins 1 to 2 should read 120VAC with the door in the locked position. Pin 3 is ground. At the opposite end, this is the 4th connector from the right on the front of the CCU.

NOTE: All the connector pins are numbered R to L.

If your continuity readings are normal for the Drive Motor and you have verified all connectors, replace the MCU.

If any of the Drive Motor windings indicate readings higher that 6 ohms, replace the Drive Motor.

Washer won't start, makes a clicking noise and than a code comes upF DL


Hi



Thanks for using FixYa. Error “dlf” or f dl means a door latch failure. This means that you’ll need to replace the door latch assembly however before doing that you can leave the washer unplugged for 30minutes so that it resets itself. In the meantime when it’s unplugged just inspect the door latch wiring to ensure all the connector plugs are intact and not loose or broken. You can access the door latch wiring harness by removing the top panel of the washer. To remove the top panel just remove the three screws that hold the panel in place in the rear of the washer. With the screws removed, the panel will slide back, and then lift off. Locate the door latch assembly behind the front panel on the right hand side. Trace all the connectors from the door latch to the Central Control Unit (CCU) and make sure they are properly seated at both ends. If after doing this still the issue is not resolved then unfortunately you have to get the door latch replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.



Thanks

Kenmore washing machine flashing dl he4t


"Fdl" is a Door Latch Failure error code. This is an indication that either the door latch mechanism has failed, the Central Control Unit (CCU) has failed, or you have a problem with the interconnecting wiring between the two.

I recommend you refer to the tech sheet to determine how to determine which component is causing the error code.

Each one of these washers come with a technicial data sheet inside the unit. To access, you will need to remove the lower toe panel under the door. The panel comes off by locating and removing the screws under the bottom front edge of the washer. You may have to prop the front feet of the washer up for better access to the panel screws (a 2x4 works well for this). With the screws removed, the panel will dro down, then come off. The tech sheet will be located either directly behind the panel, or affixed to one of the interior cabinet walls. Included in the tech sheet are all the error code definitions, troubleshooting data, wiring diagrams and diagnostics procedures.

If you determine the door latch is defective, the following link explains how to replace one:

http://www.fixya.com/support/r3575840-replacing_a_door_latch

NOTE: A simple test that you can try to see if the latch has failed, or if the problem is with the Central Control Unit (CCU) is to lightly tap on the control board with a screwdriver at the point where the door latch connectors. There's a relay on the board that controls the locking and unlocking of the door latch. Sometimes the relay sticks, causing the error code to appear. Sometimes this can free up a stuck relay.


To access the CCU, follow these steps:

1. UNPLUG the washer.

2. Remove the top panel of the washer by locating and removing the three screws that hold the panel in place in the rear of the washer. With the screws removed, the panel will slide back, then lift off.

3. The CCU is located top center behind the wash tub. Locate the connector plug(s) that run to the door latch. Unplug each connector one at a time and reseat them. Sometimes this can restore a connection where continuity is lost due to corrosion or oxidation.

4. Attempt to start a wash cycle and see if it works. If not, as the washer tries to lock the door latch, tap the board where the door latch connection(s) are.

NOTE: The washer usually makes 4 attempts to lock the door, before it errors out.

If none of these preliminary measures work, you may need to replace the CCU. If you can get the CCU to work, but still have to tap on it each time, you should replace it as well. This may get you by in the interim while awaiting parts (if you can get it to work this way).

Replacement parts can be purchased at any of the following web sites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

I have found these sites to be reputable and provide great service. Prices differ between them, so shop and compare. The first three sites on the list also include exploded view diagrams to assist you in locating and properly identifying the part(s) you need. The Sears website will sometimes offer a refurbished CCU for much less.

If you have any questions, please post back and let me know. I hope this helps you.

HE4t Kenmore - last rinse cycle stops and flashing F11


"F11" is a Serial Communications error between the Central Control Unit (CCU) and Motor Control Unit (MCU). The CCU is the main computer for the washer and is located directly behind the wash tub. The MCU is the Drive Motor Control board and is located in the rear of the washer adjacent to the Drive Motor on the left-hand side (facing from the rear with the back panel removed). The wiring harness can also cause the error, but it is not as common a problem.

Whirlpool is the manufacturer of both model washers and recommends the following troubleshooting advice. Remove the top panel of the washer by removing the three screws holding it in place in the rear. Once the screws are removed, the panel slides back, then off. Remove the rear panel of the washer for access to the drive motor and MCU. Now check the following:

- Check the wire harness connections between the CCU, the MCU and Drive Motor. Make sure all connections are attached and making good contact. Check for any broken wires or connector pins.
- Check the Drive Motor to see if it free spins and that the belt is still attached and not slipping. If the motor is seized, replace it. If the belt is broken or worn, replace it as well.
- Check the MCU. Connector 1 is the Serial Communications Link between the MCU and CCU. Connector 2 is the connector to the drive motor. Resistance checks across pins 1, 2, & 3 are the motor windings. Connector 3 is the power supply - 120VAC should be read across pins 1 and 2 with the door in the locked position. NOTE: The connectors are read 1, 2, and 3 from the bottom to the top with the MCU installed.
- Check the CCU. Verify connectors 7 and 11 are properly installed. Facing from the front of the washer, connector 7 is the 4th connector from the RIGHT along the front. This is MCU Power. Connector 11 is the Serial Communications link from the CCU to the MCU and is located along the left hand side of the CCU (the connectors are numbered 11 through 14 back to front).
- Check the Drive Motor. Remove the connector and perform resistance checks on the motor connector pins. Readings across pins 1 to 2, 2 to 3 and 1 to 3 should read 6 ohms.

In most cases this is an indication of a failed CCU. This is an easy repair that the average do-it-yourselfer can accomplish on their own. If the washer is still under a warranty, parts and labor would be covered. With no warranty, a replacement parts will vary in price depending on where you get them. There are several good websites available that you can order parts on line and have shipped directly to you.


NOTE: Remove all the connectors from the CCU ONE AT A TIME and reconnect to see if the error code goes away BEFORE you decide to purchase a new one. It is not common, but sometimes a flaky connection can generate error codes.

Hi, I have a Kenmore Elite HE4t washer that recently started throwing F11 error codes. The first couple times I was able to reset it with ''Cancel'' or unplugging, but this time every time I did anything,...
