Here are some common issues that might need dishwasher repair:

Dishwasher not cleaning dishes properly: This could be due to a blocked or faulty spray arm, issues with the detergent dispenser, or problems with the water inlet valve.

Dishwasher not draining: This could be due to a blockage in the drain hose or pump, a problem with the drain solenoid, or issues with the timer or control board.

Dishwasher leaking water: This might be caused by a faulty door seal, a leak in the tub, or problems with the water inlet valve.

Dishwasher not starting: This could be due to an issue with the door latch or switch, a problem with the selector switch, or a malfunctioning timer or control board.

Dishwasher making unusual noises: This might be caused by a faulty pump, problems with the spray arm, or issues with the motor or fan.

Dishwasher not filling with water or overfilling: This might be caused by issues with the float switch, a faulty water inlet valve, or problems with the timer or control board.

Repairing these problems generally involves troubleshooting the specific issue, identifying the malfunctioning component, and then fixing or replacing it. Depending on the complexity of the issue, professional appliance repair technicians might be needed, especially when dealing with intricate or electrical components.

Some simpler problems might be suitable for DIY repairs if you’re comfortable with it, like cleaning the filter, checking the spray arms for clogs, or replacing the door seal.

Regular maintenance can help prevent many common dishwasher problems. This might include tasks like cleaning the dishwasher regularly, checking and cleaning the seals, and ensuring the filter and spray arms are clean and clear. These tasks can help to maintain the efficiency and longevity of the dishwasher.
