Possible Causes

Stuck drain relay on control board, Shorted drain pump wiring, Faulty water level/float switch

Safety First: Turn off power at the breaker to stop the pump and prevent damage.

Check for water in base pan: Remove toe-kick and inspect for leaks that may trigger safety float, causing continuous drain. Remove water and fix leaks if present.
Inspect wiring: Check drain pump wires for shorts or melted insulation.
Test float switch: Ensure the float switch is not stuck in the overfill position.
Control board: If wiring and float are good, the drain relay on the control board may be stuck closed. Replace the main control board.
