How to Fix Whirlpool WDT730 Blinking Lights

If you’re facing blinking lights on your Whirlpool WDT730 dishwasher, it might be a sign of an underlying issue. This guide will walk you through the common causes and step-by-step solutions to fix this problem. Let’s dive in!

Understanding Blinking Lights on Whirlpool WDT730

Blinking lights on your dishwasher indicate an error code, which helps identify the specific malfunctioning component or issue. The most common blinking patterns include:

• 1 flash and pause, 3 flashes: This usually means a float problem (the switch or the float itself).
• 2 flashes and pause, 2 flashes: Typically indicates a door strike issue.
• 3 flashes and pause, 3 flashes: Often signifies a control board malfunction.

Common Causes of Blinking Lights on Whirlpool WDT730

Identifying the root cause is crucial for an effective repair. Here are some common causes:

1. Float Problem

The float switch ensures that the dishwasher’s tub remains filled with water during a cycle. A malfunctioning float can lead to blinking lights.

2. Door Strike Issue

A door strike problem occurs when the dishwasher doesn’t properly detect that the door is closed. This issue can be caused by a damaged or misaligned door strike.

3. Control Board Malfunction

The control board manages various functions in the dishwasher, including the water intake and heating elements. If it fails, you might see blinking lights as an error code.

Step-by-Step Fix Instructions

Here are some steps to troubleshoot and potentially fix the issue:

1. Check the Float Switch

1. Locate the float switch at the top of the dishwasher tub, near the water inlet.
2. Ensure that it moves freely without obstruction and resets after filling.
3. If not, clean or replace the float switch as needed.

2. Inspect the Door Strike

1. Open the dishwasher door and look for a small metal strip near the bottom (door strike).
2. Make sure it’s intact, clean, and aligned with the door closure mechanism.
3. If misaligned or damaged, adjust or replace it as needed.

3. Examine the Control Board

Inspecting and repairing a control board requires advanced knowledge and specialized tools. It’s best to contact a professional for this task.

When to Call a Professional

If you’ve tried troubleshooting the issue with no success, or if you’re uncomfortable dealing with electrical components, it’s time to call in a professional. They can diagnose and repair complex issues like control board malfunctions.

Prevention Tips

To avoid future dishwasher problems, consider these tips:

• Regular Cleaning: Regularly clean the float switch and other accessible components to prevent buildup and malfunction.
• Door Inspection: Periodically check the door strike for damage or misalignment.
• Proper Use: Ensure you’re using your dishwasher according to the manufacturer’s guidelines.
