Dishwasher Not Draining Completely, and Other Common Dishwasher Issues Explained.



Dishwashers are fantastic appliances that save us time and effort, but they can also encounter common issues over time. Here are some of the most typical dishwasher problems:


Dishwasher Not Turning On:

  • Solution: Check if the dishwasher is properly plugged in and the circuit breaker or fuse hasn't tripped or blown. If the dishwasher still doesn't start, the problem may be with the door latch switch, control panel, or timer.

Dishwasher Not Draining:

  • Solution: A clogged drain filter, drain hose, or pump can prevent proper drainage. Remove debris and clean these components. Additionally, a faulty drain pump may need replacement.

Water Leakage:

  • Solution: Leaks can be caused by damaged door gaskets or seals. Replace the faulty gaskets or seals to prevent water from escaping. Check for cracks or damage in the dishwasher's tub as well.

Poor Cleaning Results:

  • Solution: Inadequate cleaning can result from clogged spray arms, malfunctioning spray arm components, or low water temperature. Clean the spray arms, check the water temperature, and ensure you're using the right detergent and loading the dishwasher correctly.

Detergent Dispenser Issues:

  • Solution: If the detergent dispenser isn't opening or the detergent isn't dissolving, it could be due to a faulty dispenser or clogged detergent compartments. Replace the dispenser if necessary, and clean detergent compartments regularly.

Noisy Operation:

  • Solution: Unusual noises, like grinding or banging sounds, may indicate worn-out wash impellers, worn-out spray arm bearings, or debris caught in the pump assembly. Inspect and replace these components.

Cloudy or Spotted Glassware:

  • Solution: Hard water minerals can cause cloudy glassware. Using a rinse aid and the appropriate detergent can help prevent this issue. If glassware is already cloudy, you can soak it in vinegar to remove the deposits.

Foul Odors:

  • Solution: Dishwasher odors can develop due to a buildup of food particles and detergent residue. Run a dishwasher cleaning cycle or place a cup of white vinegar on the top rack and run a hot water cycle to eliminate odors.

Rust or Corrosion:

  • Solution: Inspect the dishwasher's interior for rust or corrosion, as these issues can damage your dishes and the appliance itself. If you find any, consider replacing the affected parts or contacting a technician.

Control Panel Error Codes:

  • Solution: Many modern dishwashers display error codes when there's an issue. Consult your dishwasher's manual to interpret the code and follow the recommended troubleshooting steps.


If you encounter any of these issues with your dishwasher, follow safety precautions and, if needed, consult a professional technician for repairs. Dishwashers involve electrical and plumbing components, and improper handling can be dangerous or cause further damage. Always unplug the appliance before attempting any repairs or maintenance. Remember that safety is paramount when attempting to diagnose and fix dishwasher issues. If you are unsure about how to troubleshoot or make repairs, it's advisable to give us a call to prevent further damage or injury.
