Dishwasher Not Completing Cycle

Quick answer

If your dishwasher stops mid-cycle, first check for error codes and ensure the door is fully closed. Clear any drain clogs and verify the water supply is on. If the issue persists, the pump or control board may need inspection.

Confirm the symptom

• Dishwasher starts but stops before finishing the cycle
• No error code displayed, yet cycle doesn't complete
• Dishes are only partially cleaned
• Dishwasher makes noise but doesn't progress past a certain point

Tools and prep

• Screwdriver (flathead and Phillips)
• Flashlight for inspecting internal components
• Plumber's snake or wire hanger for drain cleaning
• Multimeter to test electrical components
• Rubber gloves for handling water and parts
• Turn off power at the circuit breaker for safety
• Shut off water supply to the dishwasher

Step-by-step troubleshooting

1. Check for Error Codes
   Do: Look at the control panel for any displayed error codes.
   Observe: If there is a code, note it down.
   Means: Error codes can indicate specific issues like a blocked drain or sensor failure.
   Next: Consult the user manual for the code's meaning and resolution.
2. Inspect the Door Seal
   Do: Check the door gasket for debris or damage.
   Observe: A damaged or dirty seal may prevent the door from closing properly.
   Means: The dishwasher may not start or stop if the door isn't fully closed.
   Next: Clean the seal or replace it if damaged.
3. Check the Water Supply
   Do: Ensure the water supply valve is fully open and the inlet filter is clean.
   Observe: Low water pressure or a clogged filter can prevent proper operation.
   Means: The dishwasher may pause or stop due to insufficient water.
   Next: Clean the inlet filter or adjust the water supply valve.
4. Clear the Drain
   Do: Remove the drain hose and use a plumber's snake or wire hanger to clear any clogs.
   Observe: Water should flow freely from the drain hose.
   Means: A clogged drain can cause the dishwasher to stop mid-cycle to prevent flooding.
   Next: Reattach the hose and restart the cycle.
5. Test the Float Switch
   Do: Locate the float switch inside the dishwasher tub and check if it moves freely.
   Observe: If the float is stuck or damaged, it may signal a water overflow.
   Means: A faulty float switch can halt the cycle to prevent water overflow.
   Next: Clean or replace the float switch if necessary.
6. Inspect the Pump and Motor
   Do: Check the pump and motor for obstructions or damage using a flashlight.
   Observe: Any debris or damage may prevent the pump from operating.
   Means: A clogged or faulty pump can stop the cycle.
   Next: Clean the pump or replace it if damaged.
7. Test the Control Board
   Do: Use a multimeter to test the control board for continuity.
   Observe: No continuity indicates a faulty board.
   Means: A malfunctioning control board can prevent the cycle from completing.
   Next: Replace the control board if it's faulty.

Common causes

Parts matching

If you need replacement parts, match your dishwasher model to the correct components.

• Check the model number on the dishwasher's door or control panel.
• Visit the manufacturer's website or a home appliance retailer for part compatibility.
• Use a part lookup tool to find the right replacement for your specific model.
• Ensure the replacement part is compatible with your dishwasher's make and model.
• Purchase parts from authorized dealers for quality assurance.

Always refer to the user manual for part numbers and installation instructions.

When to call a professional

• If the dishwasher still doesn't complete the cycle after trying all troubleshooting steps.
• If you suspect a faulty control board and are not comfortable replacing it yourself.
• If the pump or motor shows signs of damage and you lack the tools to replace it.
• If there is a persistent water leak after clearing the drain and checking the float switch.
• If the error code persists and you cannot find a solution in the user manual.
