Drain Pump Motor
The drain pump utilizes a permanent magnet synchronous motor to drive an impeller. Over time, the internal bearings can fail or the impeller can become obstructed by debris, preventing the pump from generating the necessary head pressure to lift water through the drain hose and into the sink's plumbing. This results in the complete failure of the evacuation cycle, leaving dirty water in the tub.

CONF
Drain Hose Check Valve
This component is a rubber one-way flapper valve located at the pump outlet. If the rubber becomes distorted or brittle due to high water temperatures and detergents, it fails to seal properly after the pump stops. This allows water remaining in the vertical section of the drain hose to flow back into the dishwasher tub under the force of gravity.

CONF
Drain Hose with High Loop
Internal build-up of calcium or organic matter can restrict the diameter of the drain hose, increasing the hydraulic resistance beyond the pump's capability. Additionally, if the hose is not installed with a 'high loop' or connected to an air gap, wastewater from the kitchen sink can siphon back into the dishwasher during normal sink use.
