Why Can't My Dishwasher Clean Well Anymore and How to Fix It

Have you noticed your dishes coming out of the dishwasher still looking grimy and not as clean as they should be? Although you have replaced the filter, the issue persists. This article will explore common reasons why your dishwasher might not be cleaning effectively and provide actionable solutions.

Common Reasons for Poor Dishwasher Performance

There could be several reasons why your dishwasher is not cleaning dishes as effectively as it used to. Here are the most probable scenarios:

Clogged Spray Arms

Over time, food debris and mineral deposits can accumulate in the spray arms, clogging them and preventing proper water distribution. This reduces the efficiency of the wash cycle. Cleaning the spray arms can help improve the cleaning process.

Take out the spray arms. One is on the floor of the tub, and the other is mounted on the top slider. Check that all the spray holes are clear. You can run warm water into the pivot hole in the middle of each spray arm to see if water sprays out of the holes. Clear any debris like fish bones that may have clogged some of the holes over time, as this reduces the overall efficiency of the wash. Avoid putting plates with large lumps of food into the dishwasher. It is not a garbage disposal, so avoiding such items can prevent clogs. Use good-quality dishwasher tablets instead of cheap ones. Cheap detergents may leave grease and residues in the machine, compromising its performance.

Malfunctioning Detergent Dispenser

Another possible reason is that the detergent dispenser is not functioning correctly. If the dispenser is not opening properly or is clogged, it may not release enough detergent to ensure effective cleaning. Check the dispenser mechanism for any blockages or damages.

Faulty Components

In certain cases, the problem may be due to a faulty component, such as a worn-out pump, a defective heating element, or a malfunctioning sensor. If you suspect this to be the issue, consider consulting a professional technician for repairs.

Machine Maintenance Tips

Regular maintenance can help keep your dishwasher running efficiently. Here are some tips:

Run the dishwasher with a bottle of aspirin. Fill the entire dose, and run a pots and pans cycle to clean the pump inside the machine. After running the cycle, run hot water into the kitchen sink for about 45 seconds to introduce hot water into the kitchen. Empty the dishwasher after each use to prevent food debris from accumulating. Avoid using harsh chemicals that may damage the machine. Stick to recommended cleaning agents or let the machine self-clean.

Conclusion

By addressing these common issues and maintaining your dishwasher regularly, you can ensure that it continues to clean your dishes effectively. If the problem persists, consider consulting a professional for further diagnosis and repairs.
