Error 4 appears on digital screen. It states in

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.

Hi

Error code FH appears when No water is detected entering machine or Pressure switch trip is not detected. If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.
Press PAUSE/CANCEL twice to clear the display. If there is no water entering the unit then make sure that the inlet valves are working fine. You may need to check the continuity at the inlet valves. If the valves are fine then check whether inlet water hose, it may be plugged. Also check for inlet water screen at the valve. However, if the water is entering into the washer then the Drain pump might not be working. Also inspect the Pressure Switch hose whether it is in good condition and properly connected to Tub and Pressure switch. Also check hoses for leak and inspect the flow meter. Hope this helps...

FH: If after 30 seconds the control does not detect water entering
machine, the valves will be turned off and the error code will be
displayed. OR If the control has turned the water valves on and after
8 minutes the flow sensor has detected 10.5 gallons of water passing
through it, but has not detected the pressure switch trip, the valves will
be turned off and the error code will flash.
Press PAUSE/CANCEL twice to clear the display.
If there is no water in the unit:
-Make sure that both valves at the water source(s) are turned
on all the way.
-Check for plugged or kinked inlet hoses or plugged screens in
the inlet valves.
-Verify inlet valve operation.
If there is water in the unit:
-Verify drain pump operation.
-Verify that the pressure switch hose is in good condition and
properly connected to tub and pressure switch.
1. Verify there is not a siphon problem.
2. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves,
pressure switch, drain pump, flow meter, and
Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power
6. Verify pressure switch operation.
7. Verify flow meter operation by blowing air through the part and
measuring the resistance.
8. Verify CCU operation by running a Diagnostic test or any cycle.

Blow out that tubing from the tub, might be all it takes.

Hi
Error F20 means Water Inlet Problem-no water or insufficient water supply.
This issue can appear due to faulty inlet valves or due to blocked inlet hoses. Also check the filter screen at inlet valve, clean them if they are dirty.
Select PAUSE/CANCEL twice to cancel the cycle. Unplug the washer or disconnect the power. Now check whether water faucets completely turned on?
Make sure that the water inlet hoses are not frozen. If above things seems to be fine then you would need to replace the water inlet/fill valve.
Hope this helps... Please post back if you need more information.

If the flow meter does not register 10 and 1/2 gallons of water in 8 minutes the FH code appears.
Could be a bad flow meter, sensor, wiring harness is loose or a bad CCU Central Control Unit.
At the RINSE cycle if water enters the machine you must time the water fill for 8 minutes or less.
If water does not enter the machine suspect the CCU as bad.

Hi

Error code F indicates that dishwasher control has detected a fault with dishwasher filling. This is due to faulty water inlet valve. Please check for clogged water inlet valve. Water inlet valve part#35

I had a error 004 on a Beaumark Model: BM-DW9702-WH Dishwasher which caused it not to run. The Manual stated it was To MUCH INLET WATER. I replaced the Inlet Valve with Part#: DW-53. The Dishwasher now runs great!

"IE" is an error code that indicates a water inlet problem on an LG washing machine. This code will appear if the washer is not filled to the correct level within eight minutes after switching it on. Possible causes for the IE code include partially closed taps, improperly attached inlet hoses or clogged inlet hose filters.

Hello and welcome to fixya.

I'll start by saying you're right the "01" error code is indicating a fill problem has been detected by the control.

Have you tried just a "cold" water wash ? If not try selecting "quick wash" and on the dial turn it to #1 "cold" in the cotton setting see what happens. Do the same and select #3 "hot". If the error occurs in one and not the other, observe and either focus on the hot water valve or the cold main wash valve ( I don't think it is the cold prewash valve or the error would occur immediately ).

In fact I suspect it is the main wash cold valve ( dual valve ) since you haven't indicated the error occurs during prewash and the hot water valve is energized in prewash by design to help rinse out the detergent no matter what cycle or temp. you selected.

Having said all that, here's what you're dealing with. Even though you appear to have sufficient water flow as you stated you checked for, the electronic control doesn't think it is correct.
There are several factor's which could possibly be causing this error, a couple you've mentioned.

They are...


Water supply turned off. ( obviously not in this case )


Water inlet hose filters (strainers/screens) blocked. ( you've said you cleaned them out )


Water pressure too low. ( must be no lower than 14.5psi and a max. of 145psi )


Water inlet valve(s) has failed. ( this doesn't appear likely...at least at first, not completely failed based on your description...but the control may think it has. If you have an ohm meter you can check it. the coils should have a value of between 2.7 and 3.3k ohms. That means 2700ohms and 3300ohms. If not within those values the control will detect the value being incorrect , hence displaying the "01" error. Change the valve, Bosch part # 265772, or repairclinic.com # 467537.
The Hot water valve if need be is Bosch part # 171295 or repairclinic.com # 423900 )


Control module has failed. ( Not very likely either...but possible...if not the valves. )
