F20 on Whirlpool Duet (WFW9600TW01)

With a one year old whirpool duet, I'm getting an F20 code on any cycle, hot or cold. It happens exactly 6 minutes into the wash cycle, after water has filled the wash tub. I replaced the flow meter, but replacing it had no effect.

I cleaned the screens on the inlet hoses. There is no siphon problem (no issues maintaining water level), and there is no drain pump problem (no issues draining tub once pump engages).

Could it be the pressure sensor (aka water level switch)? Or is it something else? I tried blowing into the tube leading to the sensor to clear it. I also tried blowing into the sensor itself, and it triggered the drain pump (which then stopped, after I stopped blowing). But the problem keeps returning.

Thanks for your help.

"F20" is a water inlet problem. This indicates that you have no water or insufficient water supply. What Whirlpool recommends to do is unplug the washer and check your water inlet screens to ensure they are not clogged, check the inlet hoses for kinks, and to make sure your taps are turned on (duh! I know it sounds stupid, but I've seen it before).

To check the water inlet screens you will need to turn off the water supply and disconnect the hoses where they connect to the back of the washer. The inlet screens are located inside the tap fittings and sometimes will collect with sediment and rust depending on your water source. Some hoses also have sediment screens. Check them as well if you have them. Use cotton swabs to clean the screens, thoroughly.

Checking the hoses and taps is self-explanatory. The water supply coming into the washer should be at least 10-25 psi. Insufficient water pressure can cause problems with slow fills and/or error codes due to insufficient pressure. If you haven't had any problems before, I would suspect dirty inlet screens and/or a inlet valve failure.

If you need to replace the water inlet valve, carries the part. Just type in your model number in the Search menu and look for item #1 under the "Dispenser Parts" heading (part #8182862). The part runs about $52.00.

I hope this helps you. If you need further assistance, please post back with any questions/concerns you may have.

F/H is a no water fault code, so i would recheck your incoming water supply, or look to a problem with the inlet water valve.. if your using stainless steel hoses, form the manufacture lableld FLOOD SAFE, these maybe your issue as well they have a buitl in water shut off, htat may be failing preventing water from entering

From the book :

If too much detergent was used:

—Run a Normal cycle without adding any detergent.
This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged

Unplug the machine. Unscrew the 3 screws under the front edge of the washer. The service technician manual is attached to the panel that slides down and off. Find F21 code. See suggested procedures. Note: My drain pump filter had a baby wash cloth in it along with some change that was disrupting the flow. It is exceptionally easy to remove, clean, and reinstall. Just line up installation notches when reinstalling. Whirlpool should have mentioned this filter in the User & Care Guide, but I could not find it anywhere in there.

Getting f20 error code, how to check flow meter operation

Check for stuck socks or something just under the door seal at the bottom of the drum. Check filter for blockage and all outlet pipes. Check the pressure switch hose for any holes as it may have rubbed on the drum and created a small hole in it. Make sure flow meter is level and not at any angle.

I am having trouble with my washer. It is showing the F28 error code and then when I get that fixed, it shows the F20 error code. Can you please tell me what to do to get it running again. Thanks

F20 I believe is low water flow. On the intake fitting on the back of the machine where the hot and cold hose hook up there is a fine screen inside the fitting on the machine. My cold water screen was clogged from stuff in old pipes. Cleaned it and no more e F20

The code f 20 flashes on my duet front load washer what does this mean

The F20 code for insufficient water going into the machine. Checked the hoses and water valves at the wall to make sure high pressure water is going to the washer.
You can try a different Cycle water temp setting. Like Cold/Cold or Hot/Hot to see which valve is not letting in the water.

There has been some know failures of the cold water inlet valves. That Whirlpool part number 8540751.
I hope this information has been helpful.
Good Luck.

This one is complicated, and could involve drain pump operation or pressure switch hose condition. Behind the bottom panel, there is a detailed troubleshooting guide, and goes into detail about possible solutions to this problem. The bottom panel has three small bolts (facing outward), remove them and the panel comes off, and the guide is in plastic, glued to the back of the panel. Hope this helps.

What is the F20 error code?

F-20 error code in Whirlpool Duet Sport washing machine is indication of inadequate water supply. Check both hot and cold water supply lines to make sure machine gets enough water intake. If you do not have a hot water supply to the machine you can only run it with the cold temperature setting. This machine does not have an internal water heater and relies on the hot water supply from the house water heater.
