11 Signs You Need To Replace Your Dishwasher

Dishwashers are a great convenience to have in the home. They make washing dishes much easier and quicker than in previous generations.

However, they can also be expensive to repair when something goes wrong.

If you notice any of these 11 signs mentioned below, it might be time for a new dishwasher!

1. The Dishwasher Makes a Loud Noise

If your dishwasher makes a loud noise, it’s probably time to replace it.

The sound might be coming from one of the moving parts inside or outside the machine.

These parts may be grinding against each other and rubbing together tightly.

If you notice the dishwasher making unusual noises such as loud banging and clanging, this is an indication that there may be something wrong with the machine’s motor.

It will need to be replaced soon but it can also mean there are worn-out parts in your appliance.

2. The Dishwasher is Leaking Water

It should not leak water anywhere near its door, but if you notice puddles around it, it’s a point of concern.

The leak could be coming from the hose, inlet valve, or drain pump.

Dishwashers with these leaks are not repairable, often cause water damage, and need to be replaced.

3. The Dishes Do Not Get Clean

If you notice that your dishwasher does a good job of cleaning, it might be a sign that the water is not getting to your dishwasher.

The most likely culprit for this problem is clogged filters or an obstruction in the line.

This could be caused by food particles that are stuck on dishes and need more time to run or are caused by a clogged filter.

A dirty dishwasher is not only bad for your machine’s longevity, but it can also lead to rust and bacteria that will make the dishes less sanitary.

4. The Dishwasher Doesn’t Start at All

There is a good chance that the dishwasher doesn’t work because its timer or circuit board might be broken.

In this case, it’s time to replace your old one with another new and efficient appliance if you want clean dishes in no time!

5. The Dishwasher Doesn’t Agitate Properly

This is an important sign that your dishwasher’s motor needs to be replaced.

It can damage the electronic components of the dishwasher due to constant friction.

The problem could also lie in a faulty timer, relay switch, or drive belt.

6. Rusty Water Comes out during use

The water coming from the dishwasher could be rusty because it is possibly contaminated with minerals.

It can also happen if your inlet valve is faulty and not shutting off completely when you use the machine. This causes mineral deposits to build up on its walls.

If you have an older model with metal parts like racks or detergent dispensers, they may be hardening due to exposure to water.

7. Clumps on Dishes and Stains in Silverware

If you notice clumps and stains then it may mean there is too much detergent build-up or food residue inside the machine.

The water jets will become blocked and not as effective, which can make the machine less powerful.

8. Frequent Service Calls from a Technician

A technician might be needed more often if there is an electrical issue with your dishwasher.

You may find that the machine stops during cycles. These are both signs that replacing the appliance may need to happen soon.

9. Unusual Smell When Running Cycle

A strange smell, not coming from food prep but rather something else.

It may be mold, mildew, and mustiness that could be the result of bacteria build-up on your dishwasher’s drain filter.

This needs to be replaced as soon as possible.

Your dishwasher may start to smell for other reasons, ensure to curb this to avoid more issues.

10. Inconsistent Cycle Times

Dishwasher cycles take a certain amount of time.

If you notice your dishwasher is running too quickly through cycles or it’s taking much longer than usual, this could mean that the appliance has a broken timer and will need to be replaced.

11. Unusual Water Temperature

If dishes are coming out lukewarm instead of hot water when they used to come out steaming hot, there is a good chance you have a leakage in your unit.

Even if the dishwasher is not making any unusual sounds or running unusually long, it’s worth checking out since this type of issue can lead to other problems with the machine.


So, when is the right time to replace your dishwasher? If you notice that your dishes aren’t getting clean, or it starts making a loud noise, those are telltale signs that you need a new one.

It’s also important to be mindful of any leakages and rust on the inside as these can indicate an issue with the water supply line.

When in doubt, contact a professional for expert advice on whether or not this appliance needs replacing.
