If you have a Kenmore Elite F20 washing machine error in your system, this instruction manual may help.
Approved: Fortect
The number F20 indicates that the control did not fill the tank with water. It is said that water will go inward and reach the edge of the door before a malfunction occurs. There is a flow meter that shows that water is entering this washing machine. If the meter is defective, the error usually occurs quickly.
@dilligaff F20-Technik that you are having a problem with the waterblock on your washing machine. “If the washing machine does not fill when you see the F20: make sure you have flood protection devices on the water supply hoses so you can clean the washing machine. If so, these devices may be the source of your problems.
How do I fix error code F20?
To reset error code f20 to zero, do not enable the malfunctioning spa wash program. To do this, turn off the main washing machine for 10-20 minutes and then turn it on again. If the error usually disappears from the display, the problem has been successfully resolved.
