WHIRLPOOL WDT750SAKZ Not Draining

Drain Pump Motor

The drain pump is a synchronous permanent magnet motor prone to mechanical seizure when foreign objects (such as glass or hard seeds) bypass the filtration system. Over time, the internal seals can also fail, allowing water into the motor windings, causing an electromechanical failure that prevents the impeller from achieving the necessary RPM to overcome head pressure in the drain hose.

Drain Hose

Corrugated drain hoses are susceptible to grease and lipid accumulation, which restricts the internal diameter and increases fluid friction. This mechanical resistance eventually exceeds the pump's discharge capacity, resulting in standing water remaining in the tub at the end of the timed drain increment.

Cylindrical Fine Filter

The triple filtration system uses a micro-mesh screen that can become occluded with calcium deposits or bio-film. If the intake side of the pump is starved of fluid due to a clogged filter, it cannot create the required pressure differential to move water into the discharge line, causing a 'short-drain' condition.
