Why your Dishwasher may be Making a Clicking Sound (+ Fixes)

Is your dishwasher making a clicking sound? Are you wondering if this is normal and therefore requires attention?

If so then this post may be of help. While the designs and common faults of a dishwasher can vary from one model to another (and the fixes too), this post highlights some common causes of clicking in dishwashers that may apply to your model too.

Note: Always consult your dishwasher manual and do not hesitate to contact a qualified dishwasher technician.

Is it Normal?

Some types of clicking are normal. Some brands and models of dishwashers use specific electronic control systems that make a clicking sound as the dishwasher switches from one program to another.

Therefore discerning when clicking is an issue is important.

When is Clicking a Problem?

If the clicking is a new occurrence, hasn’t happened before in the history of the dishwasher, or it just sounds unusual then it is worthwhile investigating further.

Do not hesitate to contact a qualified dishwasher technician.

Why can Cause Clicking Sounds in the Dishwasher?

In addition to the electronic controls described above, there are other possible causes of the clicking sound.

Note: Always listen intently as this can provide clues to the likely source and help you identify the fault faster.

With that said, here are some of the possible reasons why there might be a clicking sound in your dishwasher.

#1. The rotating sprayer arms may be worn and have now developed lower than the recommended clearance.

This causes the arms to periodically knock against objects at the bottom of the dishwasher.

To confirm if this is the issue

Disconnect the dishwasher from the wall outlet. Remove the trays and carefully manually rotate the sprayer arm.

Does it knock against any object? If it does, you may need to get a replacement.

Order a replacement with the same part number and recommended by the manufacturer and fit it. Check if this stops the clicking sound.

#2. The circulation pump may be failing. The pump can develop a clicking sound during its operation life.

The circulating pump is responsible for building up the pressure of the water that is then jetted over the dishes to clean them.

Speak to a qualified dishwasher technician for your particular brand and model to confirm if this is an issue.

If confirmed as faulty, order a replacement circulation pump assembly as recommended by the manufacturer.

Do not hesitate to contact a qualified dishwasher technician.

Closing Thoughts

If the dishwasher makes a clicking sound during the washing cycle, it might be part of its electronic control system depending on the design of the dishwasher.

If it sounds unusual or it is a recent occurrence then there’s probably a fault that needs further investigation.

At a minimum check the clearance of the rotating sprayer arms and the circulation pump.

Do not hesitate to contact a qualified dishwasher technician.
