I have the Kenmore Oasis Elite Top Loader and I am almost always getting a LF reading on the washer. It never completes a full load. What does LF mean?

Hi and welcome to FixYa, I am Kelly

LF = Long Fill

This is caused by either low water pressure or dirty inlet water valve screens. Turn off the water at the wall connection and remove the water hoses at the washer connection. (NOTE hot and cold installed positions) Use a thin knife blade on the outside of the inlet screens and lift them out of the water valve. Wash them under slow running water by rubbing your fingers on both sides of the screen. Once the screens are clean reinstall them in the inlet water valve. Re-connect the washer fill hoses. Just for grins... check the wall connection of the water hoses to make sure there are not HOSE screens at the wall end of the hoses.

(As a retailer of home laundry equipment we always installed fill hose water screens at the wall connections due to the local water supply having bouts of micro debris.)
You can clean the washer screens but if the installer also added at the wall connection hose screens you may still have the problem of a slow fill. Just check.

If after doing the above and you know you have good water pressure you may have a problem with the inlet water valve itself in that debris has got past the inlet screens and blocked the diaphragm passage. IF this has happened the only fix it to replace then inlet water valve.

Thanks for choosing FixYa,
