Washer fills extremely slow. Hoses are fine water

LF error means "Long Fill". Whirlpool uses a flow meter that detects the flow of water entering the washer. If this flow meter does not detect the correct amount of water entering the washer it will sound the LF error code. Often this repair can be made with out calling an appliance repairman and without ordering parts. Start by removing the washer fill hoses; both the cold and the hot water hoses. Check for proper water pressure from the house. To do so, turn the water on and put the hose inside the washer or a bucket.

If water pressure is good, check the water valve inlet screens. Most residential washing machines have inlet screens. The screens prevent minerals from clogging the solenoid. With the hoses removed, you can visually inspect the water inlet screens. If the water valve screens are clear the inlet valve with the screens itself will need to be replaced. To replace the water valve, remove the top of the washing machine. Three screws hold the top down. The screws that hold the top down are on the back of the top panel. Once removed the top will slide back and off. Now remove the wire harness that connects to the valve. One screw holds the valve to the washers cabinet. Removing the screw and sliding the valve over will release the valve from the back panel enabling you to complete your repair.

One last thing to check is the fill hoses. These front load washers call for a lot of water quickly. So if you have stainless steel braided flood-safe hoses, they will trip for no reason at all. Replace these flood safe hoses with more traditional hoses. If the hoses are good and you haven't found anything slowing down the flow of the water, your electronic inlet water valve is just faulty on the back of your washer and will need to be replaced because it's just not allowing water flow into the washer correctly.
Here is the valve to order in case it is faulty.

There is a problem with the water supply. This could be a symptom of kinked hoses, clogged filters in the intake valve or low water pressure.

Turn off the water shut-off valves and disconnect the hoses from the washer and then the shut-off valves. Place a bucket under the hoses to catch any water that drains out of the hoses. Check the filters both on the washer and at the shut-off side of the hoses. Sometimes, you need to use needle-nose pliers to pull out the filters from the intake on the washer. Make sure that the hoses are not kinked when you reinstall them. You may want to replace the hoses. There are some hoses that will seal themselves if they detect a leak. This will slow the water flow to the washer.

While you have the hoses off the washer's intake, test the water pressure by measuring the water flow into your bucket when you open the valves.

Also make sure that the washer discharge hose is not below the washer's water level for your load size. This leads to the water flowing in and then out of the washer before it fills the machine.

I hope this helps.

Check for kinked or clogged water supply hoses(s). Be sure to make sure that if there is a screen-like filter in the supply hoses or at the inlet on the wash machine, that it is clear.

Shut the water supply off. Start the washer to fill on warm wash / rinse to relieve the water pressure in the hose. Shut off the washer. Unscrew the hose connection from the washer and direct both hoses into the washer tub (or other container). Turn the water supply on. Both hoses should discharge water evenly and forcefully, then shut the water off. If the flow was uneven, slow or poor - clear obstructions in / or replace the hose(s). Next, inspect the water inlet on the washer. Clear any obstructions, dirt, etc. Reconnect the hoses and try again. If flow is still lacking, there may be obstructions in water lines or valves INSIDE the machine.

This is a result of a restriction in any one of several places. Start with the washer off / unplugged from the outlet and shut off the water supply that feeds the washer's water supply hoses. The hot a cold water valves (those that are turned off independently of each other) should require the same number of turns to shut off. If not - one is open more than the other and could be a cause for the slow fill. Unscrew the hot AND cold water hose connectors from the washer. Inspect the inside of the connector to ensure there is nothing obstructing the hose itself. Make sure the rubber washer is seated properly, too. Check the entire length of both hoses to be sure there are no kinks or evidence of crushing. Also look for stretched circumference hose that indicate it could breakat any time. Damaged hoses should be replaced promptly to minimize chances of flooding should a hose burst. Hold the ends of the hoses inside the wash machine in such a way that splashing is reduced. Open the water supply and determine if the flow of water is the same or different for the hot and cold water. If the same, the problem is at / in the washer. If unequal flows are detected (with both valves opened the same amount) , the issue is probably with cold water supply or shut off valve. You'll probably have to call a plumber if the difference in flow bothers you that much.

If the flow is the same, it could be a problem with the water inlet or water supply solenoid inside the washer itself. Many washers have a strainer or filter inside the water supply connections. Check yours for foreign objects, debris or build up and clear any found.

Reassemble and and make sure connections are tight (do not use a wrench to tighten) enough to prevent leaking and turn of water supply. Operate the washer and compare cold and hot water flow while filling the tub. If still unequal, you'll have to either call for repair or look further for a restriction in the solenoid valve or deeper inside the machine if it bothers you that much or is painfully slow to fill.

I hope this helps and good luck. Please rate my reply - thanks!

Might be a bad inlet valve. To confirm, swap the hot and cold hoses to your washer so that the cold water feeds the hot water connection and the hot water feeds the cold water connection. Turn off both hot and cold water faucets. Set the washer for a warm water wash. Turn on the cold water faucet, and check the flow. Then turn off the cold water faucet, and turn on the hot water faucet and check the flow. If the cold water flow fill slowly, then the problem is with the inlet valve.

It an easy part to obtain from an appliance supply house. To install disconnect the hoses to the back of the machine, and remove the back panel to get access to the valve. Should only take a couple of minutes to remove and install. Hope this helps you.

It's on the back of the washer. The hoses which are connected to the water supply also connect to the water inlet valve on the other end of the hose. You'll probably have to remove a rear panel to access it where the hoses go in the back.

Both hoses must be connected to a valve or capped off.

ck to see if fill hoses are connected correctly and you have good water flow through BOTH hoses to washer connection..if control senses slow fill it will f20..do not try to use cold water onlyauto temp will try to use hot to adj prest temps and will fault if no water flow detected if ok ckd screens in washer end to be sure they are clean ..also ck to see if drain hose is proper height and not in stand pipe too tight ..water may be siphoning out and washer will not fill in allowed time

take the hose off the cold water valve and check the screen on the water valve ,make sure the cold water is on all the way and the hoses are on the right valves get a water bucket hold the cold water line in it open the cold water valve to check the pressure
