I turn it on -water starts as usual lid locks --water starts again and keeps running but agitator does nothing --water keeps running for few minutes and shuts off and light "L F"comes on and machine is making slight humming sound ; then I shut it off -----turn it on drain and spin cycle and it works good----checked hoses for kinks and screens for dirt -,allseems good thanks
You will want to make sure that the drain hose is not pushed too far into the standpipe which could cause a siphoning effect. If this checks ok and the pressure hose is not pinched or kinked and that it is connected to the outer tub. Also make sure that there are no holes in the pressure hose. If this checks ok then access the tech sheet and do test number 2 on page 4 for the log valve to determine what issue could be.
