What could be causing my dishwasher to make noises?

Noise is a common problem with a dishwasher. There can be many causes for a noisy dishwasher, ranging from rattling noise due to stacked dishes being too close, loud grinding noise due to water connection issue, scraping noise due to wash arm damage and loud banging noise due to water hammer.

How can I fix loud noises in my Electrolux dishwasher?

To fix the problem of a noisy dishwasher, there are several potential solutions to try:

Run a cycle without dishes: The first step is to run an empty cycle to see if the noise persists. If it does, then further troubleshooting should be done.

1. Check the water connection: Check the water connection that connects to the dishwasher and make sure there are no kinks or loose connections. If the connection is loose, tighten it securely.

2. Inspect the wash arm: Inspect the wash arm for any damage or broken pieces. If it is damaged, it could cause scraping noises during washing cycles.

3. Get a water hammer arrestor: A water hammer arrestor is designed to reduce the loud banging noises from the water pressure fluctuation. Install the water hammer arrestor near your dishwasher and that should help reduce the noise from a noisy dishwasher.

Replace the drain pump motor: If you still have a noisy dishwasher, it may be time to replace the drain pump motor.

When should I contact a professional appliance repair technician for a noisy dishwasher?

If none of the solutions above have improved your noisy dishwasher, it may be time to contact a professional appliance repair technician. They will have the expertise and the proper tools to diagnose the problem and determine the best course of action.

Expert tip

If you need to replace the pump motor, make sure to switch off the power supply to your noisy dishwasher before attempting to start removing any parts. This will ensure that you do not damage the machine or put yourself in any danger.

Check seals and gaskets: Inspect any seals and gaskets around the dishwasher door to ensure they are not worn or damaged, as this could be causing loud noises during a wash cycle.

Check door closure latch: Check the door closure latch and make sure it is working properly. If it is not working correctly, then further adjustment will need to be done.

Adjust float switch: Check the float switch and adjust it if necessary. The float switch keeps water from overflowing and can get stuck in the on position, causing loud grinding noises.

Clean the filter: Clean the filter of the dishwasher to remove any food particles or grease buildup which could be causing noise.

Check the wash cycle settings: Check the wash cycle settings to make sure that the dishwasher is not set too high or too low.

Inspect the inlet valve: Inspect the inlet valve for any clogs or blockages. Clear out any debris or buildup and test the dishwasher again.

Test spray arms: Test the spray arms to ensure that they are working correctly. If they are not spinning properly, they could be causing loud banging noises.

Insulate the walls: If the dishwasher is located near any walls, consider insulating the walls to reduce the noise.

Check the impeller fan: Check the impeller fan for any damage or obstruction. If there is any, replace the impeller fan as soon as possible.

Replace the pump motor assembly: If the dishwasher is still making loud noises after all the solutions above have been attempted, replace the pump motor assembly.

If your Electrolux dishwasher is making loud noises, there are many potential causes and solutions. These include checking the water connection, inspecting the wash arm, installing a water hammer arrestor, cleaning the drain, replacing the drain or wash pump motor, and checking the seal and gaskets, door closure latch, float switch, filter, wash cycle settings, inlet valve, spray arms and impeller fan. If none of these work, it may be time to contact a professional appliance repair technician.
