Could a failing Drain Pump Assembly cause the MAYTAG MVWB765FW to have symptom: Not Draining Water?

The drain pump motor is responsible for the centrifugal evacuation of water from the tub. Over time, the internal seals can fail, allowing water to enter the motor windings and cause a short, or the plastic impeller can become decoupled from the drive shaft. This results in the pump 'buzzing' or humming without actually moving water through the discharge hose.

Could a failing Lid Lock Assembly cause the MAYTAG MVWB765FW to have symptom: Not Draining Water?

The control logic of this high-efficiency washer requires a 'Closed and Locked' signal before it will energize the drain pump for the spin-drain sequence. If the solenoid or the internal microswitch within the lock assembly fails, the cycle will pause indefinitely or fail to initiate the drain phase. This is a common safety-protocol failure that prevents operation even if the pump itself is functional.

Could a failing Water Level Pressure Switch cause the MAYTAG MVWB765FW to have symptom: Not Draining Water?

This sensor monitors the air pressure within a tube connected to the tub to determine the water level. If the sensor fails or the pressure dome becomes clogged with detergent residue, the Central Control Unit (CCU) may incorrectly 'think' the tub is empty or full. This mismatch in logic prevents the machine from timing the drain sequence correctly, often resulting in a DRN error code.
