If you’re finding your Whirlpool dishwasher not cleaning dishes fully, don’t start washing by hand! This can happen for a few different reasons with dishwashers, so don’t give up on your Whirlpool dishwasher just yet. Let’s discuss some of the most common causes of this issue and how to fix them. We will also provide some tips for keeping your dishwasher maintained so that it can function its best.

Tips for a Whirlpool Dishwasher Not Cleaning Dishes

Tired of your Whirlpool dishwasher not cleaning dishes properly? Let’s get to the reasons why this happens!

Dirty Dishwasher Filter

If you find your Whirlpool dishwasher not cleaning dishes, the first thing to do is check the filter. Over time, food particles and grease can build up on the filter, causing it to become clogged. This can prevent water from flowing properly through the dishwasher, which in turn will prevent your dishes from getting clean.

To clean the filter:

First: Remove the filter from the dishwasher, usually by rotating them counterclockwise.

Second: Rinse it under hot water. You may need to use a soft brush to remove any stubborn particles.

Third: Once the filter is clean, replace it and run a test cycle.

Fourth: You may also need to descale the dishwasher if there is a build-up of minerals on the interior surfaces. To do this, you can run an empty cycle with vinegar or another descaling solution. Be sure to follow the manufacturer’s instructions when using these solutions.

Dishwasher Not Getting Hot Enough

If your Whirlpool dishwasher leaves dirt on dishes consistently, it’s possible your water is not getting hot enough to remove food. If you notice a lack of hot water in other areas of your house as well, it’s likely that the water heater is set too low. The water heater should be set to at least 120 degrees Fahrenheit to ensure that the dishes are properly cleaned.

To adjust the water heater:

First: Locate the water heater and find the thermostat.

Second: Adjust the thermostat to a higher setting and wait for the water to heat up.

Third: Once the water is hot enough, run a test cycle.

Be very careful when turning your water heater up, as turning it too hot can cause burns.

Dirty Or Blocked Spray Arm

If the dishwasher spray arm is dirty, it can prevent water from reaching all of the dishes and result in your Whirlpool dishwasher leaving dishes dirty. This will cause them to come out dirty. To clean the spray arm:

First: Remove the spray arm by unscrewing it from the dishwasher.

Second: Rinse it under hot water, using a soft brush to remove any particles.

Third: Replace the spray arm and run a test cycle.

It’s also possible that the holes in the spray arm are blocked. If this is the case, you’ll need to clear the holes using a toothpick or other sharp object.

And finally, make sure nothing is obstructing the spray arm. If there are any dishes in the way, move them so that the spray arm can rotate freely. If your dishwasher is making noise, this might be causing both problems.

Dishwasher Not Loaded Properly Or Overloaded

If your Whirlpool dishwasher isn’t cleaning dishes, it might be because it’s not loaded properly. The water needs to be able to reach all of the dishes in order to really get them clean. Make sure that the dishes are not blocking the spray arm and that they are evenly spaced out in the dishwasher.
