Kenmore Washer HE3T Model 110 Will Not Power Up. Door Stays Locked.

I have disconnected the Washer And left unplugged for 5 minutes. I have plugged the unit back in and waited for 5 minutes before pressing the power button. All that happens is it chimnes (beeps). The door on the unit is locked and will not open. How can I reset the Control Board to unlock the door and power the unit up?

Lyle,

First, let me express my appreciation for you Safety First answer. Please keep up this great practice. I am following el;ectrical safety by de-energizing the unit and verifying with a Multi-Meter. The sequence you have provided in the troubleshooting is spot on. Thanks. If it is a short in the harness, I can detect using a Mult-Meter. For the Motor Control Board, are there any common issues that can be corrected or is it in the board itself? Low Quality Components like this may experience dendritic growth or tinning failures. Please let me know your thoughts.

Be sure that you follow electrical safety guidelines when using this technical information. UNPLUG the washer when accessing internal components. I understand your concern about the washer failing this soon after you bought it. Hopefully the information above will help you determine the cause of the problem. If the motor control board is shorted and needs to be replaced, I agree with your approach to replacing the washer instead of repairing it.

Your symptoms indicate that you likely have a short in the motor controller or the wiring harness going to the motor controller. A short in another component could also cause this problem. The image below shows how to isolate the likely cause of this failure. UNPLUG the washer when accessing internal components. If you can perform the test shown below, you may be able to find a short that is dragging down the DC voltage for the user interface control board and preventing the washer from powering up. I provided a wiring diagram in the second image in case you need it. If you need more help, reply with additional details and we will assist you further.

The washer is a Model 110.49962603. I have tried to power it up and it will not power up unless I disconect the MCU harness at the CCU. When I power it up in this manner it will start to cycle the machine. I will the reconnect the MCU harness and the machine will time out with a F70 or F71 error. Is there a method to reset the MCU similar to a computer motherboard (shunts). This machine has been having intermittent F70 error for the last few month and now it appears to be completely out of sequence. At $423 for a new MCU this unit will be sitting cubside. It is a shame since it is only 15 months old. What a piece of junk. Any suggestions are welcome.

Since the control is not unlocking the door, you can manually unlock it by

unplugging the washer

and removing the bottom front service panel as shown in the image below. Your washer may have 3 screws instead of 2. Remove the screws and pull the service panel forward and then off of the washer. You can then carefully reach up along the inside of the front panel and pull down on the manual release tab that is on the bottom of the door lock assembly until it clicks. You should then be able to open the door.

Once you get the door open, check for water in the tub. If the tub does have water, then you can use a wet/dry shop vacuum to remove the water. Place a shallow pan under the pump clean-out filter that is shown in the second image (with the washer still unplugged). Pull out the clean-out filter and check for a clog or obstruction in the drain pump. Check the drain line and the washer drain for a clog or restriction. Reassemble the washer and test it. If the washer still won't drain and you find no obstructions in the drain path then you could have a failed drain pump.

If the washer was not full of water, then you could have a problem with the door lock assembly. The third image shows how to access the door lock assembly. With the washer still

unplugged

, access the door lock assembly and check the wiring harness connections. If these connections are okay but the lock assembly will not unlock and lock properly then you may need to replace it.

When the washer was beeping, it probably recorded a fault code even though it did not display it on the console. With a full model number, we can normally provide you with information on recalling a saved error code that can also help you diagnose and repair the washer. Reply with that full model number if you need more help.

Having the washer not start and locked would be frustrating. I found a similar question from a previous post and some information from an appliance repair web site that may help while you wait for the expert answer. I attached the links below. Hope this helps!
