Erratic water flow and temperature from laundry tub faucet..

If cold water is on and actually coming out of faucet, check screens in hoses and water valve for debris. Make sure hot and cold water hoses aren’t reversed. If all that checks ok, water valve most likely is bad although it also could temperature switch or control board.

try to do cold cycle first without doing warm cycle first

Since your question is so vague (is it a shower, tub/shower, lavatory, kit. sink or laundry tub faucet) I'd have to say that the flow restrictor in the aerators or showerhead is clogged up. Just unscrew and remove and either clean aerator or sh.head out and/or remove flow restrictor permanently. If that doesn't work turn off water and disconnect supply tubes from faucet and run them into a bucket and turn water back on to check for volume. If you have plenty of water at supplies then remove faucet and take defective faucet back to where it was bought and get another one!

LF error code indicates that there is a water supply problem.

Are both the hot and cold water faucets turned on? Turn on the water. Check the household faucets to see if the hot and cold water faucets are turned on. Completely open both faucets for proper fill.

NOTE: Both hot and cold water must be connected to the washer and turned on. The washer will not properly operate with only one incoming source of water.

Are the water inlet hoses kinked? Straighten the water inlet hoses.

Are the water inlet valve screens on the washer clogged? Turn off the water and remove inlet hoses from the inlet valves in the back of the washer. Inside the inlet valves are screens. Remove any accumulated film or particles from the screens. Reinstall hoses, turn on water, and check for leaks. See the Installation Instructions for details.



Is the water pressure less than 10 psi? If the water pressure is too low, the washer may not properly operate. To find out your exact pounds-per-square-inch (psi) value, contact your local water utility company.

Is the drain hose extending more than 8" (20.3 cm) into the drainpipe? The drain hose may be too far inside the drainpipe (standpipe) or laundry tub. Drained water can siphon back into the washer if the drain hose extends too far. Make sure the drain hose does not extend more than 8" (20.3 cm) into the drainpipe or laundry tub. Using the U-shaped drain hose form as described in the Installation Instructions will provide the appropriate length of drain hose in the drainpipe or laundry tub.

The drain hose may be too far inside the drainpipe (standpipe) or laundry tub. Drained water can siphon back into the washer if the drain hose extends too far. Make sure the drain hose does not extend more than 8" (20.3 cm) into the drainpipe or laundry tub. Using the U-shaped drain hose form as described in the Installation Instructions will provide the appropriate length of drain hose in the drainpipe or laundry tub.

Is the drain hose taped onto the drainpipe? Is the top of the drainpipe covered with tape?
Do not seal the drain hose into the drainpipe with tape. The drain hose should be loose, yet secure. There must be a gap between the drain hose and the drainpipe to allow air to flow. The air gap will break the suction. This will keep water from being continuously sucked out of the machine (siphoning) as it fills.


Is the drainpipe (standpipe) less than the minimum height of 39" (99 cm)?
Make sure the top of the drain is at least 39" (99 cm) high (as measured from the floor). If the drain is below 39" (99 cm), the water will start to flow out of the machine due to gravity. The flow of water can create suction, (siphon) and the water will continue to drain out of the washer.

To remove the error display, press Pause/Cancel once.

If Pause/Cancel does not work:

1. Unplug the washer or disconnect the power for one minute.
2. Plug in the washer or reconnect the power.
3. Re-select the cycle and press Start.

NOTE: If the error remains on the display, and all of the other questions above have been checked, call for service.

Hope this helps (remember to rate this answer).

This is a condition known as syphoning. Your drain hose on the washer needs to go up before it connectes to the house drain. It needs to rise as high as the washing machine top then hook over the drain pipe. If the drain hose is pushed too far into the drain pipe this can also cause syphoning.

Here are some tips to help describe this better.

Is the drain hose extending more than 8" (20.3 cm) into the drainpipe?
The drain hose may be too far down inside the drainpipe (standpipe) or laundry tub. Drained water can siphon back into the washer if the drain hose extends too far. Make sure that the drain hose does not extend more than 8" (20.3 cm) into the drainpipe or laundry tub. Using the U-shape drain hose form (as described in the Installation Instructions), will provide the correct length of drain hose in the drainpipe or laundry tub.

Does the hot water flow in your other household faucets seem OK? If not, the problem could be lime build-up on the heating coils of your hot water heater. You should drain your hot water heater once a year. You will notice a hose hook up at the bottom. Hook a water hose to that, drain the hose to a place outside that is LOWER than the hose hook-up (gravity), then open the valve on the water heater, BUT BE SURE THAT YOU HAVE TURNED THE ELECTRICAL BREAKER TO THE WATER HEATER OFF BEFORE YOU DO THAT. Once the water heater drains, turn the valve(faucet) on the water heater all the way to the right (off), and when it is filled throw the breaker in your breaker box back to "on"so the water can begin heating.
Now, to the problem at hand: If the ONLY hot water flow problem is the tub, you've got a blockage either in the hot water line between the water heater and the faucet, or a blockage/lime buildup in the faucet itself. Hope that it's the faucet, because if it's not, it could be ANYWHERE between the water heater and the bath faucet.
My best advice is that you have the tub faucet replaced. It sounds as though you are not sufficiently adept to do that yourself (no insult intended). While a qualified plumber is in there, he should be able to tell if the hot water blockage is in the faucet or further back in the system. By the way, you don't have to replace the faucet with a single handle unless you just want to. Good luck!

it's being sucked out by siphoning through your sewer pipe .Probably a siphon problem . Check your drain hose to make sure hose is not stuffed too far down drain and air can get between the hose and the drain pipe . If you have tapped the hose to the drain to keep water from coming out the drain pipe , go to home depot or an appliance parts house , and get a siphon break . When a washer fills , but water level doesn't rise in the machine ,

no the tub faucet is the only faucet that is wide open you might have to not run full blast on the faucet , your tankless water heater is under sized for the application, to many gallons per min going thru the unit, look at the rating chart for your unit, the r94 is only 9.4 gallons per min, and a tub faucet can be upto 5 gallons per min, depending on the faucet,,
