The timer on my MVWB750WQO washer is not moving on as it should. A load set to run in 41 minutes is taking an hour or more to run. We also have a code of LF showing from time to time. We have replaced the hoses. We have tried resetting the timer as well. what else can we do? We received no manual for the washer. When I put in the model number no manual is found. Any help with that? Thank you
