5 Signs It’s Time to Replace Your Dishwasher

While there are no hard-and-fast rules about when it’s time to replace a dishwasher, there are some signs you can keep an eye out for that can help you make your decision. On average, a dishwasher is expected to last for about ten years, but this can vary depending on use and other factors like brand and water type. If your dishwasher is getting close to that ten-year mark but you’re not sure if it’s time to say goodbye, check out this list of signs it’s time to replace.

1. Frequent Repairs

If you’ve noticed an uptick in your dishwasher’s faults lately, it’s a good sign it’s time for a replacement. While some repairs are necessary, constant large repairs indicate it’s time to say goodbye. A good rule of thumb is that if the repair costs more than half the price of a replacement appliance, it’s better to just purchase a new model. If your dishwasher is close to the ten-year mark, it’s better to be even stricter—we recommend not paying for any major repairs at all if your dishwasher is older than around eight years.

Some major repairs that are a red flag include:

Electrical issues
Pump malfunctions
Faulty motor

2. Loud Operation

A loud dishwasher is not only annoying, it’s a sign there’s something wrong. Grinding or rumbling noises are a sign that the components are getting worn out, and failing to act can cause these issues to worsen. While some faults that cause noise can be minor, such as misaligned spray arms, issues with the pump or motor are more serious and are often a sign your dishwasher is at the end of its lifespan. Modern dishwashers tend to operate more silently, so you will likely notice a massive improvement in the peace of your home when you do decide to upgrade!

3. Drainage Issues

If you notice drainage issues in your dishwasher, make sure you rule out a clogged filter or hose before you make any serious decisions about replacing your dishwasher. Make sure you:

Remove the filter and thoroughly clean it.
Thoroughly clean the filter housing.
Check the drain hose for clogs and kinks.
Ensure the drain hose is properly positioned to allow for optimal water drainage.

If you’ve ruled out these causes, the drainage problems may be more serious and may warrant replacing your dishwasher altogether. We recommend getting the advice of a professional before making your decision.

4. Decreased Performance

If your dishwasher is not performing as well as usual, it may be a sign it’s time for a replacement. This can be due to minor issues like blocked spray arms or filters, but it can also be due to aging parts caused by wear and tear. Make sure you check the following:

Ensure the filter is clean, as a blocked filter can prevent your clothes from rinsing properly.
Check to see if the spray arms can properly rotate, and ensure that the holes in the spray arms are not blocked.

If you can’t find any obvious cause of the decreased performance and your dishwasher is close to ten years old, it’s a good sign that it’s time to look into purchasing a new model.

5. Leaks

Leaks are a sign of a serious fault in a dishwasher and should always be investigated immediately. If the seals of the dishwasher are damaged or if the hoses are cracked, these can be relatively easily replaced, but if the leak is due to cracked or aging parts inside your dishwasher, then you may need to replace the entire thing. Leaks can cause expensive damage to your home and can also cause mold and mildew growth, which can pose health hazards to you and your household.

Extending Your Dishwasher’s Lifespan

While no dishwashers last forever, there are some precautions you can take to ensure your model lasts as long as possible.

Clean the filter regularly to avoid obstructions getting stuck in the drain pump or hose.
Use the recommended detergent type for your dishwasher to avoid residue.
Regularly use a commercial dishwasher cleaner to avoid lime buildup.
Deal with minor repairs quickly to avoid any problems getting worse.
Try to wait for your dishwasher to be full before running a cycle, as running fewer full loads creates less wear and tear than frequent smaller loads.
Use the cold water or eco cycles whenever appropriate, as colder water creates less wear and tear for your dishwasher.

Choosing Your Replacement

When you decide it’s time to replace your dishwasher, make sure you carefully consider your options. Ensure the replacement meets your needs by checking out the following factors:

Capacity

Some dishwashers have a much larger capacity than others, making them perfect for large families and households.

Size

If your dishwasher is built into the cabinetry, make sure the replacement model will fit.

Energy

If energy efficiency is important to you, look for a model that has been awarded an Energy Star by the US Environmental Protection Agency or the US Department of Energy.
