Troubleshooting Whirlpool Dishwasher Drainage Issues

If your Whirlpool dishwasher isn’t draining, it could be due to a faulty component. Read on to discover how to diagnose and fix the problem.

Whirlpool is a well-known brand that produces a range of household appliances, including dishwashers. Whirlpool dishwashers are designed to clean dishes quickly and efficiently while using minimal water and energy. They offer a variety of features, such as different wash cycles, adjustable racks, and a variety of loading options.

If your Whirlpool dishwasher is draining, it means that the water is being removed from the dishwasher’s tub at the end of a wash cycle, or during a cycle if necessary. This is an essential part of the dishwasher’s operation to ensure that your dishes are properly cleaned and rinsed.

Signs That Your Whirlpool Dishwasher Isn’t Draining Properly

There are several signs that may indicate that your Whirlpool dishwasher is not draining:

Water Remains

If you open your dishwasher after the cycle has finished and there is still water in the bottom, it is a clear sign that your dishwasher is not draining properly.

Dirty Dishes

If your dishes are not coming out clean after a wash cycle, it could be because the dishwasher is not draining properly, which can leave dirty water and detergent on the dishes.

Unpleasant Odor

If you notice an unpleasant odor coming from your dishwasher, it could be because of stagnant water that has not drained properly.

Strange Noises

If you hear strange noises coming from your Whirlpool dishwasher during the wash cycle, it could be because the water is not draining properly and is causing the dishwasher’s pump to work harder.

Slow Drainage

If you notice that the water is draining very slowly or taking a long time to drain, it could be because there is a clog in the drain or a problem with the pump.

If you notice any of these signs, it is important to troubleshoot and fix the problem as soon as possible to prevent damage to your dishwasher and to ensure that your dishes are cleaned properly.

Why Your Whirlpool Dishwasher Isn’t Draining and How to Fix It

Let’s dive into the common reasons why your Whirlpool dishwasher may not be draining and some easy fixes.

Firstly, it’s important to understand that a dishwasher’s drain function is essential to get your dishes clean and sanitized. If your dishwasher isn’t draining properly, it can lead to standing water in the bottom of the unit and cause unpleasant odors, mold, and mildew growth. So, let’s get to the bottom of why your Whirlpool dishwasher may not be draining and how to fix it!

Clogged Garbage Disposal

If your Whirlpool dishwasher is connected to the garbage disposal, it’s important to check if the disposal is clogged. Over time, food particles can build up in the disposal and block your dishwasher’s drainage path.

You can clear the blockage by turning off the power to the disposal, unplugging it from the outlet, and using a flashlight to locate and remove any visible debris.

Blocked or Clogged Drain Hose

Another common reason why a Whirlpool dishwasher may not be draining is due to a blocked or clogged drain hose. The drain hose is responsible for draining the dirty water out of your dishwasher and into the sink’s drain.

Over time, the drain hose can get clogged with food particles or become twisted or kinked, leading to poor drainage. You can try removing and cleaning the drain hose or replacing it altogether.

Faulty Drain Pump

If the garbage disposal and drain hose are not the problem, it’s possible that the drain pump is malfunctioning. The drain pump is responsible for pumping out the dirty water from your dishwasher, and if it’s faulty, it can’t do its job.

You can check if the drain pump is functioning correctly by manually turning the blades and checking for any blockages or damages.

Blocked Air Gap

An air gap is a small device located on the sink’s rim, which prevents dirty water from flowing back into the dishwasher. If the air gap becomes clogged, it can cause the dishwasher to not drain properly. To fix this, you can remove the air gap and clean it with a toothbrush and vinegar.

Full Dishwasher Filter

The dishwasher filter’s job is to trap food particles and debris, preventing them from clogging the drain or spray arms. If the filter is full, it can hinder proper drainage. You can clean the filter by removing it and washing it under running water or in the dishwasher’s sink.

Blocked or Damaged Check Valve

The check valve prevents dirty water from flowing back into your dishwasher after it has drained. If the check valve is blocked or damaged, it can prevent proper drainage. You can try cleaning the check valve or replacing it if it’s damaged.

Improper Installation

If your Whirlpool dishwasher is not installed correctly, it can cause drainage issues. For example, if the drain hose is not installed properly or is too long, it can lead to poor drainage. Make sure to follow the manufacturer’s installation instructions carefully to avoid this problem.

Malfunctioning Control Board

If all the other components of your Whirlpool dishwasher are functioning correctly, but it still won’t drain, it’s possible that the control board is malfunctioning. The control board is responsible for regulating your dishwasher’s functions, including the drain cycle. A faulty control board can prevent the dishwasher from draining correctly.

Broken Float Switch

The float switch is a small device located in your dishwasher’s tub that senses the water level. If the float switch is broken or malfunctioning, it can prevent the dishwasher from draining. You can test the float switch by manually moving it up and down to see if it clicks.

Overfilled Dishwasher

If you overload your dishwasher, it can prevent proper drainage. Make sure to load your dishwasher according to the manufacturer’s instructions and leave enough space between the dishes to allow water to circulate.

Conclusion

By following the simple steps above, you can quickly identify and fix the issue, allowing your Whirlpool dishwasher to function correctly and providing you with sparkling clean dishes! If you’ve tried all the simple fixes and your dishwasher still won’t drain, it may be time to call a professional for assistance.

Clean your Whirlpool dishwasher regularly to keep it in good condition for many years.
