Frigidaire stacker issues
 

My sister- in- law has this stacker washer/dryer combo. She bought it used and it is a couple of years old. We hooked it up and it would fill but not spin. I replaced the timer, then it would fill and spin but not drian. I repplaced the lid lock switch & the fill level switch. I blew out the air lines to the load switch. Still won't drain. I can hook up a jumper wire to the pump and it will drain that way, so i know the pump is good. Is it posible that the first timer i bought is bad? Thanks in advance for any help.
