The Touch Pad/LED Assembly, (Fig.
Central Control Unit (CCU)
The Central Control Unit is located at the top rear of the washer and is enclosed in a control box. (Fig.
The CCU receives input from the touchpad/LED assembly and directly controls the dispenser, drain pump, water inlet valves, door locking and unlocking solenoids, and heating element relay. The CCU monitors the pressure switch, flowme- ter, temperature sensor and door lock switches.
The CCU sends the customer selection input to the Motor Control Unit for proper motor operation.
The MCU operates the drive motor at varying speeds and direction based on inputs received by the CCU to complete the cycle selected. The MCU also monitors a tachometer on the motor to confirm that the drive motor is operating at the proper speed and direction.
