ROCKIT APPLIANCES REPAIR · IN-HOME SERVICE
Dishwasher Not Cleaning Dishes
Dishes that come out gritty, cloudy or still dirty usually mean the dishwasher is not getting enough hot water through the spray arms. Loading and detergent matter too, but worn parts are often the cause.
Safe checks before scheduling service
A symptom by itself does not identify the failed part. These simple checks may solve the problem or help you describe what is happening.
- Clean the filter and rinse the spray arms, clearing any blocked holes.
- Run the kitchen faucet until the water is hot before starting the dishwasher so the first fill is hot.
- Make sure tall items are not blocking the spray arms or the detergent dispenser door.
Common causes
These are the causes we find most often. Only an in-home diagnosis can confirm which one applies to your appliance.
Clogged filter or spray arms
A blocked filter or spray arms reduce water pressure, leaving food on dishes, especially on the top rack.
Weak wash (circulation) pump
A worn wash pump motor cannot push enough water through the spray arms, so dishes stay dirty even with a clean filter.
Low water fill
A partially clogged inlet valve or a low-pressure supply can leave too little water in the tub.
Heating element or water temperature problem
If the water does not get hot enough, detergent does not dissolve and grease stays on dishes.
Detergent dispenser not opening
A dispenser that does not open on time leaves detergent in the cup and dishes unwashed.
Important safety note
Do not reach into the dishwasher while it is running or while the heating element may still be hot.

Frequently asked questions
Why are my glasses cloudy?
Cloudy glasses can come from hard-water film, too much or too little detergent, or no rinse aid. If dishes are also dirty, a pump or water-supply problem is more likely.
Should I pre-rinse dishes?
Scraping food off is enough for most modern dishwashers. Heavy pre-rinsing is not necessary if the dishwasher is working properly.
What is your diagnostic fee?
The diagnostic/service call is $45 and is waived when you approve the repair.
Does the online estimate include parts?
No. The $160–$220 range is an initial labor estimate only. Replacement parts, if required, are quoted separately before the repair.
