12 Easy Fixes to Keep Your Dishwasher Running as New
1. Check and Clean the Spray Arms
One common reason for poor cleaning results is clogged spray arms. Inspect the spray arms for any debris or blockages, and if necessary, remove them and rinse them thoroughly to ensure water can flow freely. A toothpick works well for clearing any blocked spray holes.
2. Use the right programme
Check the manual and where possible use longer & hotter washes.
3. Clean the Filter
A dirty or clogged filter will prevent the water from circulating. Regularly clean the dishwasher’s filter to avoid debris buildup and ensure smooth functioning.
4. Use Quality Detergent
Low-quality or expired dishwasher detergent may be to blame for lacklustre cleaning. Invest in a reputable detergent and avoid using too much or too little in each cycle.
5. Pre-Rinse Dishes
While modern dishwashers are designed to handle most food residues, excessively dirty dishes may require pre-rinsing to achieve the best results. Generally, you should remove any 3-D food particles before stacking the dishes in the machine.
6. Arrange Dishes Properly
Properly loading the dishwasher is essential for optimal cleaning. Avoid overcrowding, and position dishes so they don’t block the spray arms or water flow. Try and arrange the dirty side to be downwards facing
7. Inspect the Pump and Motor
Is the machine making strange noises? A malfunctioning pump or motor can significantly impact the dishwasher’s cleaning ability. If you suspect an issue, consult a professional technician for repairs or replacements.
8. Run an Empty Cycle with Vinegar
To remove mineral deposits and grease build-up run an empty dishwasher cycle with a cup of white vinegar placed on the top rack. This will help restore water flow and improve cleaning.
9. Check the Water Inlet Valve
A faulty water inlet valve can restrict the water supply to the dishwasher. Inspect the valve for any issues and replace it if necessary. Some models have a mesh filter on the inlet hose which may be blocked. If you’re unsure how to clean this, check your manual for full instructions.
10. Examine the Door Seals
A dirty, damaged or worn-out door seal can lead to water leakage, reducing the dishwasher’s efficiency. Do keep the seal clean. It may be possible to replace a damaged seal, but it can be tricky & expensive.
11. Don’t Wait!
It’s best to pop the dishwasher on each evening. Let it run overnight & wake up to clean (& dry) dishes.
By waiting, some food goes hard and becomes impossible to shift.
It’s usually cheaper to run the dishwasher each evening rather than having to scrub the dishes by hand post-wash!
12. Add Salt & Use Rinse Aid
It’s super important to keep the salt topped up. Along with the rinse aid, this will help get your glasses & dishes clean & shiny. Perhaps more importantly, it will also prevent limescale buildup, meaning your dishwasher will last longer – much longer!
A dishwasher that doesn’t clean properly can be frustrating, but it doesn’t mean you need to replace it immediately. By following these 12 effective fixes, you can restore your dishwasher’s cleaning performance without breaking the bank.
Remember to keep the salt topped up & clean the filters regularly. Plus, address any issues promptly to keep your dishwasher running smoothly for years, to come.
