Dishwasher Not Cleaning Properly? 7 Troubleshooting Tips Before Calling a Repair Service

Is your dishwasher leaving you with less-than-sparkling results? Before you reach for the phone to call a repair service, there are several troubleshooting steps you can try yourself. At Grange Electrical, Wirral's trusted appliance experts, we've seen many dishwasher issues resolved with simple fixes. Here are seven tips to help get your dishes clean again.

1. Check and Clean the Filters

One of the most common causes of poor cleaning performance is clogged filters. Over time, food particles and debris can accumulate, reducing water flow and cleaning efficiency.

How to fix it:

• Locate the filters at the bottom of your dishwasher.
• Remove them according to your manual's instructions.
• Rinse them under warm water, using a soft brush if necessary.
• Replace the filters, ensuring they're properly seated.

Grange Electrical Tip: Clean your filters at least once a month for optimal performance.

2. Inspect the Spray Arms

If your spray arms are clogged or damaged, water won't be distributed effectively, leaving some dishes dirty.

How to fix it:

• Remove the spray arms (consult your manual for instructions).
• Check for any blockages in the spray holes.
• Use a thin wire or toothpick to clear any clogs.
• If the arms are damaged, they may need replacement.

Grange Electrical Tip: While checking the spray arms, ensure they can rotate freely without obstruction.

3. Ensure Proper Loading

Overloading or improper loading can prevent water and detergent from reaching all dishes.

How to fix it:

• Don't overcrowd the dishwasher.
• Ensure larger items don't block the spray arms' rotation.
• Place heavily soiled items face-down and towards the center.
• Avoid nesting items together.

Grange Electrical Tip: Consult your dishwasher's manual for specific loading instructions, as optimal loading patterns can vary between models.

4. Use the Right Amount of Detergent

Too little detergent won't clean effectively, while too much can leave a residue.

How to fix it:

• Use the amount recommended in your manual.
• Adjust based on your water hardness and soil level.
• Consider using a rinse aid for better drying and to prevent spots.

Grange Electrical Tip: If you're in a hard water area like parts of Wirral, you might need to use slightly more detergent or a water softener.

5. Check Water Temperature

Dishwashers work best with hot water. If your water isn't hot enough, cleaning performance will suffer.

How to fix it:

• Run hot water at your kitchen sink before starting the dishwasher.
• Check your water heater's temperature setting (it should be around 120°F or 49°C).
• If your dishwasher has a heat boost option, use it.

Grange Electrical Tip: If your water consistently isn't hot enough, there might be an issue with your water heater or the dishwasher's heating element.

6. Run a Cleaning Cycle

Over time, mineral deposits and food particles can build up inside your dishwasher, affecting its performance.

How to fix it:

• Run an empty cycle with a dishwasher cleaner or white vinegar.
• For vinegar, place a cup of it on the top rack and run a hot water cycle.
• Follow with a rinse cycle to remove any residue.

Grange Electrical Tip: Do this monthly to keep your dishwasher in top condition.

7. Check for a Kinked Drain Hose

A kinked drain hose can prevent proper draining, leaving dirty water in the dishwasher.

How to fix it:

• Pull out your dishwasher carefully (if it's not built-in).
• Check the drain hose for any kinks or bends.
• Straighten out any kinks you find.

Grange Electrical Tip: While checking the hose, ensure it's properly connected and there are no visible leaks.
