If dishes come out cloudy, greasy, or covered with food, the dishwasher may not be broken. Loading habits, water temperature, detergent, and routine cleaning all affect performance.

Turn off power before removing filters or checking moving parts, and use the cleaning instructions for your specific model.
1. The Dishwasher Is Overloaded
Items placed too close together block water and detergent. Keep plates separated, angle bowls downward, and avoid nesting spoons. Tall pans should not prevent the spray arms from turning.
2. Spray Arms Cannot Rotate
Spin each arm gently before starting a cycle. Utensils, cutting boards, or tall dishes may interfere. If spray holes contain visible debris, clean them using the method in the owner’s manual.
3. The Filter Is Dirty
A clogged filter recirculates food particles and reduces water flow. Remove and rinse the filter regularly. Never force a filter that does not release easily, and reinstall it securely before running the machine.
4. Water Is Not Hot Enough
Most dishwashers need adequately hot incoming water to dissolve detergent and remove grease. Run the kitchen faucet until hot before starting the cycle, and check the appliance manual for temperature guidance. Do not raise the water heater to an unsafe setting.
5. The Wrong Detergent Is Being Used
Old, damp, or unsuitable detergent may not dissolve correctly. Use fresh automatic-dishwasher detergent and the amount recommended for local water hardness. Never use regular hand dish soap; it can fill the kitchen with suds.
If basic checks do not solve it, review local appliance repair service options and describe what changed.
6. The Detergent Dispenser Is Blocked
A large pan or utensil can prevent the dispenser door from opening. Keep the area in front of it clear. A dispenser that remains closed with no obstruction may need repair.
7. Water Is Not Filling Properly
Low water level can result from a restricted inlet screen, faulty valve, float problem, or supply issue. If the dishwasher sounds different or runs with very little water, stop using it and schedule diagnosis rather than opening the water valve assembly.
8. The Pump or Motor Is Weak
A failing circulation pump may produce weak spray pressure, humming, grinding, or intermittent cleaning. Pump replacement requires access beneath the tub and should be performed by a technician.
When Dishwasher Repair Is Needed
Call for service when cleaning remains poor after correcting loading, detergent, filter, and spray-arm issues. Leaks, burning odors, breaker trips, or standing water should be addressed promptly. Review our broader guide to appliance warning signs for issues that should not wait.

Final Takeaway
Load carefully, keep the filter and spray arms clean, use fresh detergent, and confirm proper hot-water supply. If the dishwasher still lacks water pressure or circulation, professional repair can identify the valve, pump, motor, sensor, or control problem.
