LF indicates low water flow detected by the washer. This could be from a problem with the incoming water flow, the inlet valve or the fill level sensor. If the drain hose is inserted too far down in the stand pipe (or the end is too low going into a sink), you can get a siphon that gives the same error. You'll see and hear this - raise the end of the drain hose to a point above the max water level of the washer when full.
You'll need to check a few things. First, make sure that the incoming water shut-off valves open and close properly. Take the hoses off the washer and place them in a bucket. Open the shut-off valves one at a time and check the flow rate. Replace older inlet hoses. Make sure that there is no debris in the hose filter and the washer inlet filter (if your model has one). Watch the water flow into the washer. Do you get full-flow or a trickle? If the flow is limited, the inlet valve may need to be replaced. If the flow is good and the washer fills to the normal level, then the pressure switch that checks how much water entered the tub in 8-10 minutes could be damaged or the air hose could be clogged.
I hope this helps. Note: for some washers, you need water flow from both the hot and cold valves. I got a low flow when I assumed a cold wash didn't need the hot water coming in. Please add a comment with the model number of the washer if you need a parts diagram/list.
The usual cause for having the water flow out of the washer during the fill is that the drain hose is positioned too low in the stand pipe or sink. The end of the hose must be positioned above the maximum fill level of the washer tub. Otherwise, you will get a siphon pulling the water to the lower level and out into your drain.
If you have a stand pipe, pull the drain hose up. Next check how high the water will get in the washer and return the hose making sure that it is above that level. You may need to increase the height of your stand pipe if the washer tub water level is above the height you can position the drain hose. (Different washers can have different high water levels. The only restriction is that the drain pump on most washers can't push the water more than 7-9' high depending on the unit.) If you have the hose going into a sink, you need to make a similar adjustment. This could be a little bit harder to measure and secure the pipe depending on the sink.
I hope this helps. The stand pipe is usually PVC. Adding some extra pipe of the correct diameter will require a coupler and another length of pipe cut to the needed length. Add some PVC cleaner and glue to ensure the pipe doesn't separate from the vibration of the washer.
It probably has some coins stuck in the pump or a kink in the hose. If the washing machine won't drain, remove the access panel, and follow drain hose into machine and to the pump.You will need something to catch the water. Take pliers and sqeeze clamp and slide away from pump. Pull hose off and drain water. Remove coins from pump inlet and reassemble. If it is overflowing where it drains into the wall, you will need a pipe snake or a plummer.
If water is not entering the washer, check that the incoming water valves are open and water flows through them. (Take off the hoses and put a bucket under the pipes.) Make sure that any filters are not clogged (for example with bits of damaged washer). Make sure that the hoses are not kinked. Next take off the hoses from the washer's fill valve and check if the filters are clogged (not present on all washers). Try replacing the hoses (there are anti-flood hoses that will seal themselves if they sense a leak). If that doesn't help, then the valves probably need to be replaced.
If water is entering the washer, check the filters at the inlet valves for partial blockages. Next check your water flow rate. (If the flow is too low, the washer may shut down. Check your manual for details or add a comment with the model number of your washer.) Next check if the water is being siphoned into the drain. This will occur if the drain hose is not positioned properly in the stand pipe (or sink). If the end of your drain hose is lower than the washer water level, this can happen.
30 degrees or 30 inches. The drain stand pipe is separate from the washer and usual plumbed in behind the washer. You bring the the drain hose up to the top of the standpipe and then push the end (forming an upside down U at this point) into the top of the open 2-3" diameter PVC pipe and secure it so that it won't back out (but do not seal the opening). Nylon ties or hose clamps will work. The height requirement is so that the bottom of the hose in the standpipe is above the water level in the washer - this avoids the drain siphoning the water out of the washer. Check how far into the standpipe the drain hose has been pushed. If it is below the level of the water in the washer, back it out. Check the height of the standpipe. Many washer manuals recommend a 34" standpipe (max height of 48") based on the drain hose length on the down side of the U. Also make sure no one sealed the top of the standpipe against air entering the pipe. (Often this is done because of a back up in the drain, pull the drain hose out and get the pipe cleaned out and then put the hose in to the proper distance. Then leave the top of the standpipe open.)
Make sure that the drain hose does not stick too deep into the stand pipe or drain tub. The end of the drain hose should be elevated about 9 inches higher than the top of the washer to prevent siphoning. Cut the excess of the drain hose if it sticks too deep into the stand pipe or drain tub.
Please specify the brand and model of the washer if the problem is not resolved above for specific troubleshooting guide.
Check your drain hose. It only goes into the drain stand pipe from 4 to 6 inches. Insertion any further will creat a siphon and constantly drain the tub. The stand pipe needs to be at least 36 inches from the floor.
Depending on your model number, Maytag dishwashers on one model have combined drain pump & spray arm pumb. On other Maytag units these pumps are stand alone pumps. Check to make sure that: 1: drain hose to drain pipe(disposal) is open and flows well, do this by disconnecting the hose from disposal end and lay flat (in a pan) on floor and see if water comes out, if it does hose is clear of gunk. 2: Check garbage disposal inlet tube where drain hose connects, if your recently installed disposal then you may have forgot to remove plastic plug, 3: Turn spray arms by hand and make sure they spin freely, 4: make sure that when you close the door it latches and you can hear the pump running.
If all the above are ok, then you have a drain/motor gone down and will need to replace it. Give us a model number and we can advise better where else to look.
This is a pretty common problem and the solution is quite simple. It’s caused by the drain hose siphoning water out of the washer
tub. There are two common causes for siphoning and I’ll explain both of
them below.
One
cause for siphoning is simply that the drain hose discharge is below
the fill level of the washer tub. This picture shows the minimum drain
height needed to avoid siphoning.
Another common cause for siphoning is not having an air break
between the drain hose and the drain stand pipe. Usually, this isn’t a
problem since the drain hose diameter is usually much smaller than the
diameter of the drain stand pipe. But sometimes folks will
inadvertently remove the air break by duct taping the drain hose to the
stand pipe. They might do this because the drain hose keeps popping out
of the stand pipe when the washer pumps out the tub. Other times, the
drain hose might fit into the stand pipe with a tight interference fit.

The problem is most likely your drain. If there is no air break at the drain,( a gap where the hose goes into the pipe so air can enter) Your water will siphon out of the machine. Also make sure your drain pipe is higher than the tub of your washer and you only want about 6 inches of the drain hose sticking into the pipe. If you have water coming back out of the pipe when the machine drains, you will need a plumber to clean the pipes or replumb the drain. New washers pump out faster than older ones did and they need a good drain to handle the flow.
