A clogged filter, blocked drain hose, or malfunctioning drain pump are common causes. Food debris often builds up and prevents water from flowing out. Cleaning the filter and drain area usually fixes minor issues.

This can happen due to clogged spray arms, low water temperature, or incorrect detergent use. Hard water buildup or overloading racks can also reduce cleaning performance.

Leaking can be caused by a damaged door gasket, loose hose connections, or a cracked tub. Using too much detergent may also lead to overflow and suds-related leaks.

If your dishwasher doesn’t start, check the power supply, door latch, and control lock settings. A defective door switch or electronic control board may also prevent operation.

A faulty heating element, thermostat, or vent fan can prevent proper drying. Also, not using rinse aid often leads to wet or spotty dishes after the cycle.

Grinding or humming sounds could mean something is stuck in the pump, or the wash motor bearings are worn. Rattling noises are often caused by loose dishes or utensils hitting spray arms.

Odors build up when food particles remain trapped in the filter, sump, or spray arms. Regular cleaning with vinegar or a dishwasher cleaner helps eliminate smells and bacteria.

It could be blocked by tall dishes or caused by a faulty dispenser latch or control mechanism. Make sure nothing obstructs the dispenser door during the wash cycle.

Error codes often point to drain faults, water inlet issues, or heater problems. Consult your manual or have a technician diagnose the error for accurate repair.

If you notice persistent leaks, electrical issues, or error codes that won’t clear, it’s time to call a technician. Continuing to run the dishwasher could cause further damage or safety risks.
