Whirlpool WDT730 Not Draining: Causes and Solutions

A malfunctioning dishwasher can be a real inconvenience. If you find yourself with a Whirlpool WDT730 dishwasher that’s not draining, don’t panic! This guide will walk you through common causes and provide step-by-step solutions to help get your dishwasher back in working order.

Understanding the Problem

The primary function of a dishwasher is to clean your dishes by washing them with water and then draining that water away. If your Whirlpool WDT730 isn’t draining, it means the pump or another component responsible for removing water from the dishwasher might be faulty.

Common Causes of Whirlpool WDT730 Not Draining

1. Clogged or Obstructed Drain

Over time, food particles and debris can accumulate in the dishwasher’s drain, preventing water from draining properly.

2. Faulty Drain Pump or Motor

The pump or motor responsible for moving water out of your dishwasher might be malfunctioning due to wear and tear or electrical issues.

3. Garbage Disposal Issues

If your dishwasher is connected to the same drain as your garbage disposal, a problem with the disposal can prevent water from draining into the main sewer line.

4. AirGap Problems

An AirGap is a small device that prevents backflow of grey water from the sink into the dishwasher. A clogged or improperly installed AirGap can cause draining issues.

Step-by-step Fix Instructions

1. Check the Drain

1. Unplug the dishwasher: Always disconnect the power for safety before troubleshooting.
2. Access the drain: Locate the garbage disposal or the dishwasher’s bottom front panel where the drain hose connects. Remove any screws and gently lift the panel to access the area underneath.
3. Inspect for clogs: Use a flashlight to look through the drain hole for food particles, debris, or other obstructions. If you see anything, carefully remove it using long-nose pliers or a drain snake.

2. Inspect the Drain Pump and Motor

1. Access the pump area: Depending on your model, you might need to remove the lower dish rack or access panel to reach the pump.
2. Check for damage: Visually inspect the pump and motor for any signs of wear, cracks, or foreign objects stuck in the impeller. If you find anything unusual, it might be best to contact a professional.

3. Test the Garbage Disposal (if applicable)

1. Reset the garbage disposal: Turn off the power at the circuit breaker, then press the reset button on the disposal (usually located on the bottom). Turn the power back on and run the disposal for a few seconds to clear any clogs.
2. Manually turn the blades: If the disposal seems jammed, use a disposal wrench to manually turn the blades. Be cautious, as they can be sharp.

4. Inspect the AirGap (if applicable)

1. Locate the AirGap: It’s typically found near your kitchen sink, often protruding from the countertop.
2. Clean or unclog the AirGap: Remove any debris using a small brush or your finger. If it appears damaged, consider replacing it.

When to Call a Professional

If you’ve followed these steps and your dishwasher still isn’t draining properly, it’s time to call in a professional technician. Complex issues like faulty pumps or motor problems usually require specialized tools and expertise.

Prevention Tips

1. Regular Cleaning: Rinse dishes thoroughly before loading and clean the filter regularly to prevent clogs.
2. Use a Dishwasher Cleaner: Occasionally run an empty cycle with a dishwasher cleaner to keep your appliance in good condition.
3. Check Connections: Periodically inspect the drain hose and connections for any signs of wear or damage.
