What Usually Fails on a Dishwasher?

Common Dishwasher Problems

Dishwashers simplify daily life. A malfunctioning dishwasher quickly becomes a major inconvenience. This article explores common dishwasher failures. It identifies the most frequent issues and offers potential solutions. You will learn about the parts most likely to break and why. This knowledge empowers you to troubleshoot problems effectively. This article also helps you decide when to call a repair technician. Understanding your dishwasher’s mechanics helps you extend its lifespan and avoid costly repairs.

Spray Arm Issues

Spray arms play a vital role in cleaning dishes. They rotate, spraying water and detergent onto the dishes. Blocked or broken spray arms result in poorly cleaned dishes. Food particles can easily clog the small holes in the spray arms. Check for and remove any blockages. Mineral buildup can also restrict water flow. Soaking the spray arms in vinegar can dissolve these deposits.

Sometimes the spray arm itself cracks or breaks. In this case, you must replace the spray arm. Check that the spray arm spins freely. Utensils sometimes prevent the spray arm from rotating properly.

Checking for Spray Arm Blockages

• Remove the spray arms

  Carefully detach the spray arms from the dishwasher.

• Visually inspect the spray arm jets

  Look for any visible food particles or mineral buildup.

• Clear any blockages

  Use a thin wire or toothpick to remove debris.

• Rinse thoroughly

  Run water through the spray arm jets to ensure they are clear.

Drain Pump Malfunctions

The drain pump removes dirty water from the dishwasher after each cycle. A malfunctioning drain pump leads to standing water at the bottom of the dishwasher. A clogged drain hose can also cause this problem. Detach and inspect the drain hose and clear any blockages in the hose.

If the hose is clear, the drain pump likely requires replacement. Sometimes a damaged impeller, the rotating component inside the pump, causes the problem. A humming sound from the pump suggests a blocked impeller or a motor issue. If the drain pump motor fails, you will need to replace the entire pump.

Detergent Dispenser Issues

The detergent dispenser releases detergent during the wash cycle and a faulty dispenser prevents proper detergent distribution. This results in dirty dishes. Check for clogs or blockages in the dispenser. Clean the dispenser regularly to avoid buildup. Sometimes the dispenser spring weakens and prevents the dispenser from opening completely.

Also, inspect the dispenser for cracks or damage. If the dispenser is broken, replace it. Ensure you use the correct type of detergent for your dishwasher. Using the wrong detergent can clog the dispenser.

Control Panel Failures

The control panel allows you to select wash cycles and options. A malfunctioning control panel can make it difficult or impossible to operate the dishwasher. Buttons might not respond, or the display might not show correctly. Moisture or food debris can damage the control panel. In some cases, you can clean the control panel with a damp cloth. If the problem persists, you may need to replace the entire control panel.

A power surge can also damage the control panel’s electronics. If you suspect this, consult a qualified technician. While some control panel issues are simple to resolve, others require professional expertise. Attempting to repair the control panel yourself could further damage it or the dishwasher.

Door Seal Problems

The door seal creates a watertight barrier between the dishwasher and the surrounding cabinets. A worn-out or damaged seal leads to leaks. Inspect the seal regularly for cracks or tears. Clean the seal with a mild detergent to remove food particles and soap scum. Ensure that dishes do not obstruct the seal when closing the dishwasher door.

A leaking door seal often requires replacement and replacing the seal yourself is usually a simple task. Make sure you buy the correct seal for your dishwasher model. A properly functioning door seal prevents water damage to your kitchen floor and cabinets.
