Troubleshooting Whirlpool Dishwasher Drain Problems: The Ultimate Guide

If your Whirlpool dishwasher has stopped draining, it can be a frustrating and inconvenient problem. Luckily, most drainage issues can be resolved with a little troubleshooting and DIY repair. In this blog post, we will delve into the common reasons why your Whirlpool dishwasher won‘t drain and provide step-by-step instructions on how to fix the issue.

Clogged Drain Filter

One of the most common reasons for a Whirlpool dishwasher not draining is a clogged drain filter. The drain filter is located at the bottom of the dishwasher tub and collects food particles, debris, and other objects that can block the drain hose. To clean the drain filter:

1. Open the dishwasher door and remove the bottom rack.
2. Locate the drain filter, which is usually a cylindrical or square-shaped component at the center or corner of the tub.
3. Unscrew the filter counterclockwise and lift it out.
4. Rinse the filter thoroughly under running water to remove any debris.
5. Reinstall the filter and tighten it clockwise.

Kinked or Blocked Drain Hose

Another common cause of a clogged Whirlpool dishwasher is a kinked or blocked drain hose. The drain hose is responsible for carrying wastewater from the dishwasher to the sink drain. If the hose is kinked or blocked, it can restrict the flow of water and prevent the dishwasher from draining properly. To check the drain hose:

1. Unplug the dishwasher from the power outlet.
2. Pull the dishwasher out from the cabinets to access the back.
3. Locate the drain hose, which is usually a corrugated plastic hose connected to the bottom of the dishwasher.
4. Inspect the hose for any kinks or blockages. If the hose is kinked, straighten it out. If the hose is blocked, use a drain snake or a wet/dry vacuum to clear the obstruction.

Faulty Drain Pump

The drain pump is a small motor that pumps wastewater from the dishwasher to the sink drain. If the drain pump is faulty, it can prevent the dishwasher from draining properly. To check the drain pump:

1. Unplug the dishwasher from the power outlet.
2. Remove the drain hose from the dishwasher and place it in a bucket.
3. Start a drain cycle on the dishwasher.
4. If water flows out of the drain hose into the bucket, the drain pump is working properly. If no water flows out, the drain pump may be faulty and needs to be replaced.

Clogged Air Gap

The air gap is a small device installed on the countertop near the sink. It prevents wastewater from flowing back into the dishwasher and contaminating the dishes. If the air gap is clogged, it can create a vacuum that prevents the dishwasher from draining properly. To clean the air gap:

1. Locate the air gap on the countertop near the sink.
2. Remove the cap from the air gap.
3. Use a small brush or a toothpick to clean out any debris or buildup from the air gap.
4. Reinstall the cap on the air gap.

Faulty Door Latch

The door latch is a small switch that prevents the dishwasher from starting if the door is not properly closed. If the door latch is faulty, it can prevent the dishwasher from draining properly. To check the door latch:

1. Open and close the dishwasher door several times.
2. Listen for a clicking sound when the door is closed. If you do not hear a clicking sound, the door latch may be faulty and needs to be replaced.

Overfilled Dishwasher

If you overload your Whirlpool dishwasher with too many dishes or utensils, it can prevent the dishwasher from draining properly. The dishes and utensils can block the drain filter or the drain hose, restricting the flow of water. To avoid overfilling the dishwasher:

1. Load the dishes and utensils into the dishwasher loosely.
2. Do not overload the dishwasher with too many dishes or utensils.
3. Make sure that the dishes and utensils do not block the drain filter or the drain hose.

Troubleshooting Tips

If you have tried all of the above solutions and your Whirlpool dishwasher still won’t drain, there may be a more complex issue that requires professional repair. Here are some additional troubleshooting tips:

• Reset the dishwasher by unplugging it from the power outlet for a few minutes and then plugging it back in.
• Check the circuit breaker or fuse for the dishwasher to make sure that it has not tripped.
• Inspect the dishwasher for any leaks or water damage.
• If you are not comfortable troubleshooting the dishwasher yourself, contact a qualified appliance repair technician for assistance.
