As much as homeowners love their dishwashers, this appliance is likely to develop issues over time. While some malfunctions may require simple repairs, others may call for a replacement part. But how do you know when it's time to retire that old dishwasher of yours? Here are six signs to help you figure out if you need a new part for your dishwasher.

Poor Cleaning

If your dishwasher no longer cleans your dishes as thoroughly as it used to, it's time to check if any parts need replacement. The spray arm, which is responsible for spraying water and detergent onto the dishes, can become clogged or damaged over time. If the arm has cracks or appears loose, it's time to replace it.

Strange Noises

While it's normal for dishwashers to make noise when operating, strange sounds are a red flag that something's wrong. For instance, a grinding noise could indicate that the motor bearings or pump seal are defective. If this is the case, it's best to replace the parts to prevent further damage.


Any water leaking from your dishwasher is a clear sign that you need a new part. Check the door gasket first, as this is where leaking commonly occurs. If the gasket is worn out or damaged, it can lead to water leakage, potentially causing damage to your kitchen floor. Get a new door gasket installed as soon as possible.

Displaced Racks

If you notice that your dish racks are no longer in the right position, it could be due to a broken or worn-out rack roller. These wheels on which the racks slide tend to wear out over time, causing them to become stuck or misaligned. Replacing the old and damaged rollers will have your racks back in their place in no time.

The Dishwasher Doesn't Start

There could be various reasons why your dishwasher won't start, including faulty electronic control boards, door switches, or blown fuses. If you've checked the power outlet and found that it's working, it's best to call a reliable technician to take a look and diagnose the problem.

Rust and Corrosion

Rust and corrosion create an unpleasant look and can also cause damage to your dishwasher's interior. They can also weaken its structure or corrode essential parts, such as the wiring or heating element. If you spot any rust or corrosion, it's time to contact a professional as soon as possible.

A malfunctioning dishwasher can be a frustrating experience for homeowners, but it'll be easier if you know when to replace a specific part. Pay attention to these six signs indicating you need a new part for your dishwasher so you can have it fixed before the issue gets worse. By doing so, you'll keep your dishwasher running smoothly and efficiently for a longer time.
