What is a CCU and why would you need to replace it? The CCU on a Whirlpool front load washer is the main control board. On this particular washer there are however two other control board. The User Interface board and the MCU (Motor Control Unit).
There are several error codes on these Whirlpool front load washers that would require replacement of the CCU or would require you to check several key components from the CCU with a volt/ohm meter.
What they’ve figured out it is over time these units vibrate and shake considerable more then the top load washers. This excessive shaking and vibrating causes the solder joints on the printed circuit board to crack and brake. When one of these solder joints crack the machine most likely will throw a communication error code on the front display.
I’ve had several emails over the last month or so asking where is the CCU control board and what does it look like. I’ve snapped a few pictures of the Whirlpool Duet CCU control and wanted to share with other visitors as well as the folks who have emailed asking.
The CCU (Central Control Unit) is located on the top right of the Whirlpool Duet and Duet sport washing machines. The top of the washer is held in place with three small screws which in most cases has a size 1/4 screw head. Once the screws are out the top panel will slide directly back and off of the washing machine.
On the top front right you will see either a white or a gray board with a mass of wires running to it. All the connections on the CCU are plug and play type. Each wire harness is also keyed. So this really helps prevent wires being plugged into the wrong places a thing of the past. I still take one wire off at a time just so I don’t have to deal with a mess of wires and this also helps prevent plugging the wrong wire into the board and possibly shorting out another component.
Below is a picture of one of the most common Whirlpool washer CCU’s.
This CCU unit is held to the side of the washer with one clip and two small rounded prongs. On the side where the white wires connect there is a small plastic clip that mounts the CCU to the washers frame. Placing a flat head into the bracket and pushing out slightly will allow the board to slide back and off the frame.
With the CCU board removed you can either replace it or make a few volt ohm test right at the board. It’s one of the easiest parts to replace for any communication error code or any failed CCU error code.
