Solving the Mystery of the Whirlpool Dryer’s LF Code: How to Troubleshoot and Repair Your Dryer

If your Whirlpool dryer has an LF (long fill) code, it may be due to something as simple as a clogged lint filter. However, if this does not solve the problem, there are several other potential causes. In this article, we’ll discuss what an LF code means, and how to troubleshoot and repair your Whirlpool dryer.

What Does an LF Code Mean on a Whirlpool Dryer?

An LF code on your Whirlpool dryer means that the dryer is taking too long to fill with water. This can be caused by multiple factors, including a kinked or clogged fill hose, a defective water inlet valve, or a faulty timer.

How to Troubleshoot and Fix an LF Code

Before starting any repair, always unplug the dryer from the wall outlet.

1. Inspect the Water Supply

Check the water supply line to make sure it is not kinked or blocked. The water supply line should be connected securely to both the wall and the back of the dryer. If the line is kinked, it may be preventing water from flowing into the dryer.

2. Clean the Lint Filter

If the water supply line is not blocked, then the next step is to clean the lint filter. The lint filter is located inside the dryer’s lint trap. To clean it, use a vacuum to remove any lint that has built up on the filter.

3. Check the Water Inlet Valve

The water inlet valve is responsible for controlling the flow of water into the dryer. If the valve is faulty, it can cause the dryer to take too long to fill with water. To check the valve, remove the access panel on the back of the dryer and look for any cracks or blockages in the valve. If the valve is damaged, it should be replaced.

4. Replace the Timer

If the water inlet valve is not damaged, then the next step is to replace the timer. The timer controls how long the dryer runs and can cause the dryer to take too long to fill with water if it is faulty. To replace the timer, remove the top panel of the dryer and locate the timer. Replace the timer with a new one, making sure to follow the manufacturer’s instructions.


If your Whirlpool dryer is displaying an LF code, it may be due to a blocked lint filter, a kinked water supply line, a faulty water inlet valve, or a faulty timer. To troubleshoot and fix the problem, inspect the water supply line, clean the lint filter, check the water inlet valve, and replace the timer. Following these steps should help you get your Whirlpool dryer running properly again.
