Hi, I have a Whirlpool Duet Sport Washer about 5 years old

This answer was rated:

I have a Whirlpool Duet Sport Washer about 5 years old which has the Control Lock issue with an incessant beeping sound and "end of cycle signal" going on and off on his own will.

Yes, pressing the button for 3 seconds enables me to use the washer again. But it locks up and goes back to beeping if I just do the 3 second reset and leave it.

So I'm stuck with a washer that will work only after I reset the control lock and set the wash cycle. But once the wash is over, it goes back to beeping all on its own.

For a 5 year old washer with only 3 people in the house, not impressed to say the least.

So what is it exactly that's defective on this washer?

Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today. lets get started.


this is a CCU problem, (Central Control Unit. ) there should be 2 numbers at the end of the model # XXXXX 01,02 03 04, can you get that to me?

If you're asking about the Washer model number, I opened the front door and checked the label. It has 00 past the model # XXXXX gave WFW8300SW
So a complete number of WFW8300SW00

Or, are you asking about the CCU model # ? If so, this will take a few minutes because it's all put back together.
I got it, after looking this over your issue is not the CCU but the user interface is. these have the buttons you push to set the cycles and the control lock, the control lock button is arching and causing this to lock the control, you need to replace it. the part # XXXXX(NNN) NNN-NNNNits part # XXXXX on this diagram, this will take care of your issue, thanks Bryan

If you're correct, just for a confirming test, I suppose I could carve out the plastic overlay on top of the control lock button making sure the button moves freely before I buy another part. If the problem goes away, I know I won't be changing a part for nothing.


I guess that wouldn't hurt to try, see if you can put this in diagnostic mode,


The complete built-in service diagnostic module contains two

entry modes and three modes of operation.

Entry modes:

n Universal mode across all products. It displays error history

prior to performing any automated test.

n Quick entry and bypasses the displaying of error codes.

Operation modes:

n Display the error states that have been recorded by the


n Run through an automated test.

n Run loads to assist in diagnosing potentially non-electrical

in the OFF state before pressing the touch-pad sequence to

start the test.
