Dishwasher stops mid-cycle and will not advance; water may remain in tub.

Safety first: Disconnect power before accessing internal components.

• Note when it stops: Determine if it always stops at the same point (wash, drain, or dry). This helps isolate the failing component.
• Check door latch: Inspect and test the door latch switch for intermittent operation. Replace if worn.
• Inspect wiring: Check harness connections at the control board, pumps, and heater for looseness or burns.
• Control replacement: If all components test good and the unit consistently stops at the same point, the main control board may be defective and require replacement.
