Hi, could you tell me how many DC volts that the drive motor runs off of and does the ccu run the drain pump and water inlet valves off of AC or does it convert it to DC? Thanks
Answer John, The CCU supplies 120 VAC to the drain pump on the two wire DP2 connector on the CCU, it also supplies 120 VAC to the water inlet valves on the VH7 four(4) wire connector. There are two power sources to the MCU, the MI3 connector on the CCU supplys five(5) VDC on pin 1 and 3 (three wire connector) and 120 VAC on the MS2 (two wire) connector on ccu. We have no voltage readings to the motor from the MCU at this time.
My mom's machine will not drain and shows an error code F-11. A repairman said the Motor Control Unit needs to be replaced and qouted $398. How difficult is it to replace the MCU? Thanks for your help.
Answer Hello Robert,
The model number listed is not coming up as a valid model number. If the unit is a whirlpool Duet front load washer then it could be the MCU. The F11 error code would indicate a communicaation between the central control unit and the motor control unit. You would want to check the wire harness connections to the MCU, motor and CCU for corrosion or damage. Check the drive system for worn or failed components, check the MCU, CCU Motor and wire harness. The MCU is located on the base of the unit and can be access from the back of the unit.
When the washer is in use it sounds like gears are grinding. Could this be the motor?
Answer Hello Kasey,
You would want to check your pump to make sure that there is nothing in it causing the noise. Most likely the cause is from the rear bearings on the tub 280251 have failed and would need to be replaced
