Possible Causes

Defective electronic control board (main control board)

How to Identify: Dishwasher never enters idle state and display/control panel stays lit; resetting power does not fix; symptoms persist regardless of cycle stage.

How to Identify: Buttons unresponsive, stuck, or cause constant signals to control board making unit think cycle is ongoing.

Part: User interface control

Drain pump failing or unable to drain water

How to Identify: Dishwasher runs continuously after cycle end and water remains in tub; audible pump noise that doesnâ€™t stop.

Part: Drain pump

Stuck float switch / water level sensor

How to Identify: Float doesnâ€™t move freely when manually lifted; dishwasher may think itâ€™s always filled with water.

Part: Float switch (water level sensor)

Faulty temperature sensor / heating element causing incomplete cycle

How to Identify: Dishwasher runs continuously trying to reach target temperature; dishes not drying properly.
