How to Fix LF Error on Whirlpool Washer

Whirlpool washers have digital displays on which you may select output information for the washing cycle. An error code is typically flashed on the screen when the washer malfunctions. If the error code “LF” appears in the display, it means that the washer is taking too long to fill.

If your Whirlpool washer is currently showing LF, then it may be a result of an impedance somewhere in the supply line. Thankfully, repairs can often be made without the need to call a repairman. So before you rush off to call a technician, read this article to find out how to fix an LF error code on your Whirlpool washer.

What Does LF Code Mean On A Whirlpool Washer?

When you catch your Whirlpool washer flashing LF, it stands for Long Fill, meaning that your Whirlpool washer is taking too long to fill. This happens when the main control did not get a signal from the water pressure sensor, indicating that the tub is not filling or is not filling quickly enough. The cycle will be stopped and the LF error will be reported by the control.

Low water pressure and blocked screens on the entry valve or the water supply lines are the most common causes of the LF (Long Fill) Error. If the screens are clear and there are no obstructions, the water entry valve should be changed. Poor main control can cause this in rare situations, although the factors listed above are far more typical.

In addition to the LF error code, you may see an F8E1 code. It also indicates a problem with the washer’s water supply. Connecting both inlet hoses and switching on both the hot and cold water supply would normally solve the problem. 

The Whirlpool washer features safety sensors that detect water flow and requires water to flow via both hoses to the water valves. If the sensor does not detect the water pressure sensor in both water supply hoses, the lid will lock and the machine will go into an 8-minute pump-out mode. However, if you suspect that the control is malfunctioning, you can reset your Whirlpool washer to see if that solves the problem. 

How Do You Fix Your Whirlpool Washer When It Says LF

Whirlpool LF error code tells you that water is not being supplied to your washer the way it should, so the washer stops working to keep it from getting damaged. To get your Whirlpool washer up and running again, you must first detect where the problem is emanating from to solve the problem. 

There are a few reasons why your Whirlpool washer is showing LF. We have outlined the possible reasons and their corresponding solutions so that you can get your washer back to normal working conditions. Here you go: 

1. Check the Hot And Cold Water Valves.

Ensure that the hot and cold water supply valves are fully open. You should find the valves somewhere on the wall and open them fully if they aren’t already fully open. 

2. Check for Clogs in the Supply Hoses

If the supply valves for hot and cold water are fully open and you’re still getting the LF error message, then there might be a clog in the supply hoses. Most residences have water valve inlet screens that help to screen that prevent particles from plugging up the solenoid. To see the valve inlet screens, you need to remove the supply hoses. Once removed, you can inspect the inlet screen to see if there are any clogs there. Clear any obstructions and replace the supply hoses (more details later). Replace the filters when necessary. 

Sometimes, minerals from hard water may build up within the supply hose, making it difficult for water to flow. This usually occurs after years of use, and you may need to purchase replacement supply hoses for your washer. 

3. Straighten Bent or Kinked Hoses

If your Whirlpool washer is blinking LF and you take a look at the hoses and what you see is a bent or kinked hose (or hoses), you should breathe a sigh of relief because that may be the only problem; it can usually be resolved easily by straightening the affected hose so that water can begin to flow freely. If the hose is old and keeps bending, you may need to purchase a replacement hose. 

4. Inspect the Main Water Supply

If you have done all the above but the LF error code persists, it might help to check the main water supply to your home. If the main supply to your home is only partially open, try opening it a bit more (or fully) to increase the water pressure and solve your error code. 

In extreme weather conditions, however, the water may freeze, thereby making water supply to your washing machine impossible. In that case, you might just have to wait it out or find an alternative water source. 

How To Clean Your Washer Mesh Filters

Here’s how to clean a clogged valve mesh filter: 

Step 1 – Locate the Filter

The first thing you need to do is look for the filter’s position. It is usually located on the bottom right of the washer, so it’s hard to miss. Your model may be different though, so review the user’s manual or take a quick look at your washer to identify the filter position. 

Step 2 – Take the Filter Out

Place a washcloth beneath the opening of the filter compartment before pulling it out to ensure no water spills out and causes a mess. It’s not unusual for a small amount of water to leak, so it’s not much to be concerned about if this happens!

Step 3 – Clean the Filter

Grab an old toothbrush and scrub the washing machine filter with it. The bristles of the toothbrush should be able to reach hard-to-reach places on the filter and thoroughly clean out any particle causing an obstruction. To clean the filter, add a few drops of liquid soap in water, and scrub the filter using the toothbrush moistened in the soap solution. 

If the filter is especially dirty, make a soapy solution with hot water, then soak the filter in it for 1 hour. After that, brush the filter using a toothbrush, then replace the filter. 

Can Using Anti-flood Connector Trigger LF Error Code In a Whirlpool Washer?   

Anti-flood connections are flexible water supply connector hoses with a device that stops water from flowing in case the hose breaks. This is a safety setup in some homes that shuts off the water supply to a washing machine where it’s being used. 

However, an anti-flood connector can quickly become a burden when it triggers and shuts or greatly reduces the water supply to your washing machine for no obvious reason. This could be another reason why your whirlpool washer is blinking LF. Anti-flood connectors seem to have a very limited operational pressure range such that they can trip if the water flows too fast.  

So, the answer to the question is yes. An anti-flood connector can trigger an LF error code in a whirlpool washer. Whirlpool recommends connecting appliances directly to the water supply for optimal performance.
