IN THE WASH CYCLE THE TUB FILLS ALMOST TO THE TOP THE DRAINS. THE OL CODE THE APPEARS AT THE END OF THE CYCLE

Hi, the OL code means Overloaded..
OL flashes when the machine/motor control detects a load size that exceeds the washer's capacity.Open the door lid to clear display, remove excess laundry, then restart the cycle.

I fixed the problem "OL" before wash or rinse cycle. I noticed if I
raised the tub manually after a resonable amount of water was in
the tub the wash/rinse cycle would start. The water level sensor
was leaking air, as the tub fills slowly it looses air pressure and
misreads how much water to put into tub. When too much water is in
the tub the OL error happens. The clear air line comes up at the
outlet hose tells the control panel how much water is in tank so be
sure to remove the hose while TUB IS EMPTY. ( i made mistake of
removing hose with full tank and the washer thought it was empty
and started spinning water out into floor. So, with empty tub I
removed top panel, then pulled clear air line from control panel. I
put a dab of silicon around the tip the hose came off ( don't get
into the air hole!) , replace hose and wait for silicon to set and
done. I figured it out by my I started self and didn't have to call
a repair man. Actually I am a computer repair man in nashville -
