Whirlpool / Maytag top-load washer (VMW HE platform and classic direct-drive / belt-drive): field service manual

VMW start and load sense: the lid lock engages, then the control turns the dry load to estimate size before adding water (low-water HE wash).

VMW fill: primary hot/cold valves combine with secondary valves that route water through the dispenser; water enters only when a primary and a secondary valve are both open. A pressure sensor reports level.

VMW wash: the shifter sets the drive to agitate, so the motor turns only the wash plate or agitator. A recirculation pump on some models sprays water back over the load.

VMW shift and spin: the shifter moves to spin, coupling the basket. The control watches rotation through the rotor position sensor; if it cannot see the expected motion it flags a drive fault (F7 family). The drain pump runs, then the basket ramps up while the control checks for imbalance (Ofb/unbalance).

VMW lid logic: the lid locks for the cycle and unlocks when the basket stops. Lock failures show as LdL / F5 family codes.

Classic direct-drive: a timer controls everything. The motor turns one way to agitate and the other to spin; a neutral-drain gearcase lets the pump drain before spin. The lid switch must be closed for spin. The gearcase drives a clutch and brake; when spin starts the clutch ring releases the brake and the basket turns via the spin tube and drive block.

Belt-drive (older): the motor runs one direction; the timer energizes wash or spin solenoids that engage the transmission or basket drive, and a brake holds the basket during agitation. The lid switch cuts spin when the lid opens.
