What Are the Signs That Your Whirlpool Dishwasher Is Clogged?

If your dishwasher is clogged, you may notice that your dishes are not getting clean, and it is taking longer than usual to wash them. Also, the water is not draining correctly or leaking from the dishwasher.

Your dishwasher is one of the most convenient appliances in your home. They make cleaning your dishes, cutlery, and other kitchen items easy. But if your dishwasher is clogged, it isn’t doing its job correctly. You may have to wait until the next day or two before you can run the dishwasher again. Here are some of the signs that your Whirlpool dishwasher is clogged:

  • The water doesn’t drain from the bottom rack after the tub fills up with water.
  • Water doesn’t drain at all
  • Your Whirlpool dishwasher smells like rotten eggs
  • You notice standing water in the bottom rack of your Whirlpool dishwasher
  • The dishes in your Whirlpool dishwasher feel gritty or aren’t clean

What Is the Cause of the Water at the Bottom of Your Dishwasher?

If water is found at the bottom of your dishwasher, it is likely caused by a clogged dishwasher filter. If this issue persists, you may also need to check your dishwasher’s air gap, drain hose, drain valve, or garbage disposal.

Why My Dishwasher Not Draining After Cleaning Filter?

If you have a dishwasher and you notice that your dishwasher is not draining after cleaning the filter, there are a few possible reasons:

1. Drain Pump

If you cleaned your dishwasher filter and still the dishwasher is not draining, it could be due to blockage in the drain pump. Suppose a glass breaks inside your dishwasher, and small pieces of glass might end up in the drain pump outlet. To fix this, you need to remove the drain pump and vacuum out the area to get rid of the glass. Once you do that, you can put the drain pump back in place.

2. Air Gap

Sometimes a dishwasher needs an air gap, so air can get in and help the water drain out. The air gap is a tiny space between the dishwasher and the sink. Over time, the air gap can get clogged with yucky stuff. If the air gap is clogged, it can cause the dishwasher to have drainage problems.

3. Drain Hose

You should also check the drain hose if your dishwasher isn’t draining correctly. This hose connects the dishwasher to your sink or garbage disposal, and it’s usually located under the sink or behind the dishwasher.

If it’s not connected correctly, make sure it’s clear of food or debris. You can clean your drain hose with a drain cleaner solution or by making your solution with baking soda and vinegar. However, if you have a stronger clog, you may need a more strong drain cleaner.

How to Fix a Whirlpool Dishwasher Not Draining?

If you have a Whirlpool dishwasher that does not drain as it should, then follow the steps to fix the problem:

Step 1: Supplies and Tools You Need

Here is the list of supplies and tools that you need:

  • Bucket
  • A bowl
  • Towels
  • Soft brush
  • A Screwdriver

Step 2: Unclog the Dishwasher Filter

The dishwasher filter can become clogged over time, causing the dishwasher to become less efficient and leaving dishes dirty. To unclog the dishwasher filter, remove it from the dishwasher and clean it with a brush or a toothpick. It may be necessary to replace the filter if the filter is severely clogged.

Here are some essential tips that you should consider while troubleshooting your dishwasher:

  • Make Sure the Dishwasher Is Empty
  • Disconnect from Power
  • Remove Standing Water from the Dishwasher
  • Check the Filter
  • Unclog the filter

Step 3: Unclogg the Drain Hose

The dishwasher drain hose is a small tube that runs from the bottom of the dishwasher to the garbage disposal. Water cannot drain out of the dishwasher when it becomes clogged, so it backs up into the tub and onto your floor. You can fix this problem in less than 30 minutes if you know how to unclog this drain hose.

  • Remove the Garbage Disposal: Remove your garbage disposal and clean off as much food debris as possible. If any food is stuck inside, use a pair of pliers to pull it out.
  • Clean Out The Drain Hose: Next, clean out any gunk blocking up the drain hose by reaching inside with a paper clip or needle nose pliers and scraping it out. You should also try using an old toothbrush dipped in vinegar or baking soda to scrub away any soap scum build-up inside of it.
  • Check For Blockages In Your Pipes: If that doesn’t work, check for blockages in your pipes under your sink by flushing them out with hot water (not boiling water!). If this doesn’t work, you may need professional plumbing assistance to get rid of whatever.

Step 4: Check the Drain Valve

The drain valve is located at the bottom of your dishwasher.

  • First, unplug the dishwasher and turn off the water supply to it. Be careful not to lose any water that has already been collected in the bottom of your dishwasher.
  • Next, remove the lower panel on the right side of your dishwasher by releasing two screws at each end of the panel with a Phillips-head screwdriver.
  • Now, by hand, locate and remove any filters or particles in and around this area. If particles still block your drain valve, use a small brush or compressed air to clean out any remaining debris inside and around the hose.
  • If you still see no improvement after cleaning out all this debris, replace your drain valve by unscrewing it from its housing and attaching a new one. Ensure you securely tighten the new drain valve so it does not leak again.

Step 5: Troubleshoot the Drain Pump

The dishwasher drain pump is an essential component of your dishwasher because it helps eliminate the standing water that accumulates during the washing process. When this component fails, you may notice that dishes are still dirty after the cycle finishes. This can be caused by various issues, such as a clogged pump filter or an impeller that has broken off its shaft.

Troubleshooting tips for your dishwasher’s drain pump:

  • Inspect the drain hose. First, ensure that the hose leading from the bottom of your dishwasher to the sink is clear of obstructions. If it has been crushed or kinked, it may not allow water to flow freely when the pump is activated.
  • Inspect the motor seal on the drain pump assembly for signs of damage or wear. If you see any cracks in this seal, replace it immediately before water leaks into your dishwasher again. You can find a replacement seal at most home improvement stores or appliance parts shops.
  • Check that there are no obstructions in or around the pump itself–these could include items such as food scraps or other debris that may have fallen into there during use and clog up its function when activated by water pressure from inside the dishwasher tub area during a cycle run.
