A malfunctioning dishwasher can be a major inconvenience, especially when it’s flashing lights but refusing to start. This enigmatic behavior can leave you wondering, “What’s wrong with my dishwasher?” Fear not, for this comprehensive guide will illuminate the potential causes behind this perplexing issue.
Causes of Dishwasher Flashing and Not Starting
1. Power Issues
- Faulty electrical outlet: Check if the outlet is providing power by plugging in another appliance. If not, reset the circuit breaker or fuse.
- Loose wiring: Inspect the wiring connections inside the dishwasher and ensure they are secure.
2. Door Switch Malfunction
- Faulty door switch: This switch detects if the door is properly closed and prevents the dishwasher from starting if it is open. Replace the switch if necessary.
- Misaligned door: Adjust the door to ensure it aligns correctly with the frame and activates the door switch.
3. Water Supply Problems
- Clogged water inlet valve: Clean or replace the water inlet valve if it becomes blocked, preventing water from entering the dishwasher.
- Low water pressure: Ensure there is adequate water pressure at the dishwasher’s connection point.
4. Drain Pump Issues
- Faulty drain pump: If the drain pump is malfunctioning, water cannot be drained from the dishwasher, preventing it from starting. Replace the pump if needed.
- Clogged drain hose: Remove any blockages from the drain hose that may be obstructing water flow.
5. Control Board Errors
- Damaged control board: The control board manages the dishwasher’s functions. If it malfunctions, it can prevent the dishwasher from starting. Replace the board if necessary.
6. Thermal Fuse Blown
- Overheated dishwasher: If the dishwasher overheats, the thermal fuse may blow to prevent damage. Replace the thermal fuse and identify the cause of overheating.
7. Other Potential Issues
- Child lock activated: Deactivate the child lock feature if it is inadvertently enabled.
- Software glitches: Reset the dishwasher by unplugging it for a few minutes and then plugging it back in.
Troubleshooting Steps
1. Check for power issues: Verify that the outlet is working and the wiring is secure.
2. Inspect the door switch: Ensure the door is closed properly and the switch is functioning correctly.
3. Examine water supply: Check for blockages in the water inlet valve and ensure adequate water pressure.
4. Investigate drain pump: Listen for the sound of the drain pump running and check the drain hose for clogs.
5. Consider control board errors: Reset the dishwasher and, if the issue persists, consider replacing the control board.
6. Look for blown thermal fuse: If the dishwasher has overheated, replace the thermal fuse.
7. Rule out other issues: Deactivate the child lock and reset the dishwasher if necessary.
