7 Things to Check Before Calling for Dishwasher Repair
You unload the dishwasher expecting clean plates, only to find cloudy glasses, gritty bowls, or yesterday’s dinner still stuck to the silverware. Before running another cycle, a few simple checks may help you find the problem. If your dishwasher isn’t cleaning dishes properly, the cause could be something as simple as a blocked filter, or an issue that needs professional attention.
1. Check the dishwasher filter
Many dishwashers have a removable filter near the bottom of the tub. Food particles and grease can collect there, affecting how well water circulates and drains. Check your owner’s manual to locate the filter and follow the model-specific cleaning and reinstallation instructions. Some models use self-cleaning filters; never force a part that does not release easily.
2. Look for blocked spray arms
Spray arms need room to rotate and deliver water to the dishes. A tall pan, cutting board, or misplaced utensil may block their movement. With the machine off, check that the arms turn freely and look for visible debris in the spray openings. Follow the manufacturer’s instructions before attempting to remove or clean a spray arm.
3. Rethink how you load the racks
Overcrowded racks prevent water and detergent from reaching every surface. Keep large items from shielding smaller dishes, face dirty surfaces toward the spray, and make sure nothing hangs through the racks. Your dishwasher manual may show the best loading pattern for your model.
4. Use the right detergent and the right amount
Dishwasher detergent is formulated for automatic dishwashers; regular dish soap can create excessive suds. Follow the detergent and appliance labels for dosage, especially if your model has a dispenser designed for pods or tablets. Old or improperly stored detergent may also perform poorly.
5. Check the wash cycle
A quick or light cycle may not be enough for heavily soiled cookware. Choose a cycle appropriate for the load and follow your manufacturer’s guidance on pre-rinsing. Scraping large food scraps into the trash is usually a good starting point.
6. Consider water temperature
Water that is too cool can reduce cleaning performance. Check your dishwasher’s manual for its recommended incoming-water temperature and any guidance on running the kitchen faucet before starting a cycle. Avoid changing water-heater settings without considering household scalding risks.
7. Notice standing water, unusual noises, or repeated poor results
Water left in the tub, new grinding sounds, leaks, or dishes that remain dirty after you’ve addressed basic loading and filter care can point to a drain, pump, water-inlet, or other mechanical issue. Don’t disassemble electrical or plumbing components yourself.
When should you schedule dishwasher repair?
Sometimes a dirty dishwasher filter or a simple loading adjustment is all it takes to get your dishes sparkling again. But if you’ve cleaned the filter, checked the spray arms, and adjusted how you’re loading your dishwasher without seeing improvement, there may be a bigger issue.
Dishes that consistently come out cloudy, greasy, or covered in food residue can indicate problems beyond routine maintenance. Other warning signs, such as standing water, leaks, unusual noises, or a dishwasher that won’t complete its cycle, are also reasons to schedule a professional inspection.

Frequently asked questions
Why are there food particles on my dishes after a cycle?
A dirty filter, blocked spray arm, overcrowded rack, or unsuitable wash cycle may be responsible. Start with the owner’s manual and the simplest visible checks.
How often should I clean my dishwasher filter?
There is no single schedule for every dishwasher. Filter type, usage, and the manufacturer’s recommendations determine how often it needs attention.
Should I run my dishwasher twice if dishes are still dirty?
Repeated cycles use extra water and energy without addressing the cause. Check the filter, loading, detergent, and cycle first; seek service if the problem continues. Need a hand?
