Whirlpool Washer LF Error

Troubleshooting and Repair - LF Error Code - WTW7500GC

Whirlpool Washer LF Error is a water fill error, it stands for Long Fill. It means that the main control has not gotten a signal back from the water pressure sensor which means that water is not filling the tub or not filling the tub fast enough. The control will shut down the cycle and report the LF error.

In most cases the LF (Long Fill) Error is caused by either low water pressure, stopped up screens on either the water supply lines or the water inlet valve. If the screens are clean and not causing any kind of blockage then the water inlet valve needs to be replaced. In some cases this can be caused by a bad main control but the causes above are much more common.

Questions For Error Code LF

Lf code model wtw8500dr2

We’ve had three different teachs to our house and they’ve all tried different things. Cleaned filters assured hose is correct Nothing is fixing it for this model with an LF code would you not be able to repair the water inlet valve do you automatically go to thinking that it’s the control board

I am sure the techs tested the water inlet valve and found that the valve was good which is why they were saying it's the control board. If the valve is good and the LF error persists and there is proper water pressure being supplied to the washer then the only thing it can be is the wiring between the board and the valve or the board. 

MayTag 2000 series washer displaying the LF error code

Hi, I asked the question on May 27, 2020 and purchased the hot water inlet valve after your recommendation. Unfortunately, replacing this part did not fix the issue with the LF code either. I can complete a rapid wash cycle of 30 minutes as I could before but can not wash on the standard cycle without the cycle ending prematurely with the LF error code. Any other recommendations? Thanks

I am sorry to hear replacing the valve did not fix your problem. The only thing left that it could possibly be is a bad control board. The fill circuit on the board is bad or it's throwing a false error, either way the control is bad. 

MayTag 2000 series washer displaying the LF error code

I have a MayTag 2000 series front load washer that is about 10 years old. Over a week ago, it started displaying an LF error code about 14 minutes into the cycle. We Googled the issue and checked all the hoses and screens, replaced the water inlet valve, checked the drain pipe and checked the pressure switch to be sure it was operating but to no avail. Below is the water inlet valve that we replace with no trouble. Please let me know if there is anything else I can do to be able to use my washer again. Thanks!

Ok so you were on the right track but you bought the wrong valve, you replaced the cold water valve but you should have replaced the hot water inlet valve. It's working 14 minutes into the cycle because it's filling with cold water but when it gets to that part of the cycle of whatever cycle you are using its calling for hot water and not filling, the hot water valve is a separate valve on those models. The valve is linked below:

Was working...then just stopped with LF

I moved to a new home, and hooked up both Washer and Dryer last week. I have run several loads through without issue. Last night I ran a load...and it got to almost done then stopped. Water still at bottom of washer. I have checked both hot and cold lines...and they both have pressure. Also, there is no blockage on the intake connectors on the washing machine. Ideas?

You need to replace the water inlet valve on the machine if the screens on the valve and hoses are clear. If you need the part info just come to the site chat and give me your model number and I will be glad to help, thanks.

LF code on whirlpool duet washer

Hi, I've checked water inlet hoses and hose beneath unit. I’ve replaced the cold water inlet valve and the pressure switch. The water lines to the washer are brand new since we just installed the plumbing for this washer/ dryer. The machine works fine on the Rinse/Spin cycle selection. What is the diagnosis for this? Whirlpool model: wfw9151wy00. Thank you.

Ok so on that model it does have two separate valves for the hot and cold water intake. The issue you are having is that you replaced the wrong valve. The rinse cycle works fine because rinse only uses cold water and that valve is good. When you first start the washer it uses a mix of hot and cold water from the two separate valves so the hot water valve is bad and causing the fill to take too long on the first fill of the cycle. Replace the hot water valve and it will be fine. The valve for your model is linked below:

LF Code

I've checked water inlet hoses and hose beneath unit. All are clear. The problem is the washer KEEPS FILLING (overfilling) until the LF error and then stops. Then I press Power and the unit drains. For some reason, it will not stop filling until this error occurs roughly 5-7 minutes into the wash cycle. And because it's overfilling, when the unit drains, some water pools and overspills onto the floor during the draining. The machine works fine on the Rinse/Spin cycle selection. What is the diagnosis for this?
