How to Fix a Noisy Dishwasher: DIY Troubleshooting Tips

A noisy dishwasher can disrupt your peace at home, but the good news is that many noise-related issues can be fixed with a few simple steps. At Local Solutions Appliance Repair in St. John’s, I’m here to guide you through the most common causes of dishwasher noise and how to resolve them yourself—saving both time and money.

Step 1: Identify the Source of the Noise

Before jumping into repairs, it’s essential to identify where the noise is coming from. Typical sources include a worn-out pump motor, obstructions in the drain pump, faulty spray arms, or loose components. By listening closely, you can often pinpoint the specific sound and determine the likely cause of the problem.

Fixing Common Noisy Dishwasher Issues

1. Inspect and Clean the Spray Arm

A blocked or dirty spray arm is a common source of dishwasher noise:

• Solution: Remove the lower dish rack and inspect the spray arm for any debris or objects obstructing its rotation. Clean it under running water, using a small tool to clear any clogs in the openings. If your dishwasher has upper spray arms, repeat this process for them as well.

• Prevention Tip: Regularly rinse off dishes before loading to prevent food particles from clogging the spray arms. This simple step keeps your dishwasher running smoothly and quietly.

2. Tighten Loose Components

Over time, screws, brackets, and other components in your dishwasher can come loose, causing rattling or clanking sounds:

• Solution: Carefully examine the dishwasher’s screws, brackets, and mounting hardware. Tighten any that appear loose using the appropriate tool.

• Prevention Tip: Check these components periodically, especially if you hear a rattling noise. Keeping parts secure helps prevent noise and keeps your dishwasher in good working order.

3. Check for Worn-Out Parts

If noise persists after tightening loose components, it’s possible that certain parts, such as the circulation pump motor or drain pump, are worn out and need replacement:

• Solution: Inspect the circulation pump and drain pump for signs of wear or damage. Check for obstructions before replacing any parts, as blockages can sometimes mimic component failure. If needed, consult your dishwasher’s manual or find replacement parts online, following manufacturer instructions for safe installation.

• Pro Tip: If you’re unsure whether the part is truly worn out, consider consulting a technician before ordering, as unnecessary replacements can add to costs without solving the issue.

4. Insulate Vibrating Parts

If your dishwasher vibrates against cabinets or countertops, applying insulation can help reduce noise:

• Solution: Use adhesive-backed foam or rubber pads to insulate areas where the dishwasher contacts cabinets, countertops, or other surfaces. This dampens vibrations, leading to a quieter operation.

• Prevention Tip: Periodically check insulation pads to ensure they remain intact and effective. Insulating key areas prevents noise and prolongs the lifespan of your dishwasher by reducing vibration-related wear.

Stay Proactive with Regular Maintenance

By following these troubleshooting tips, you can fix many noise issues in your dishwasher and enjoy quieter operation. Regular cleaning and maintenance can also prevent future noise problems, so make it a habit to:

• Clean the spray arms and check for obstructions regularly.

• Tighten any loose components during routine checks.

• Rinse dishes before loading to reduce debris buildup in filters and pumps.
