Regular cleaning of both filters and spray arms can resolve this. If the problem persists, checking for hard water deposits or using a dishwasher cleaner might help.

Food Particles and Debris: Food particles trapped in the filter reduce cleaning power. Regularly cleaning the filter can prevent this issue. Ensuring proper dish loading also prevents blockages. Avoid overloading the dishwasher and follow the manufacturer’s loading guidelines for best results.

Noisy Operation

Water Sloshing Sound: A loud sloshing sound during the wash cycle can be normal, but it can also indicate an air break issue on the side of the dishwasher or a gap in the door seal. Proper installation and checking the insulation can help reduce this noise. If the noise persists, inspecting the air gap and door seals for any issues might be necessary.

Vibrations and Rattling: Vibrating or rattling sounds can arise from unsecured dishwasher components or improper loading of dishes. Ensure all internal parts are secure and dishes are placed correctly. Placing heavy items on the bottom rack and spacing out utensils can minimize these sounds.

Water Leakage

Door Seals: A common cause of leaks is faulty door seals. Regular inspection and cleaning of door seals can prevent leaks. If seals are damaged, replacing them is necessary to maintain a watertight door.

Improper Loading: Overloading or improper loading can lead to water leakage. Ensure dishes aren’t blocking the spray arms and that large items don’t obstruct the door closure. Proper loading techniques can prevent leaks and enhance cleaning performance.
