Kenmore Elite HE4t Washer (by 3 users)

My FDL signal came on. Called a repairman, he said the Door Lock assembly needed to be replaced. Said he would charge me $287.00 to do it. He replaced it tried the machine and the FDL signal came back on????? So he then went out to read his manual...He came back and said the hinge needed replaced and he could do that for another $50.00. I said well replace my Door Lock Assembly because apparently it isn't bad..I told him I would hold off on the repair til I spoke with my husband. he charged me $89 and left. The washer worked ok (as long as I didn't overload it) however I did a load today and the FDL Signal came on. I unplugged the washer for 30 minutes ran it and it seemed fine??? I don't Know what to do... Any suggestions would be appreciated! I am tired of fighting this machine daily.

We have a Kenmore Front Loader Elite 2005 Washer and got the FdL error also. Called the repair guy and he played with the wiring for the door locking mechanism and got it to work twice but when I tried it (just before I wrote him the check) it didn't work. His solution and it may be the right one is to order a new computer/brain and door locking mechanism. This just happened and I told him I would get back to him on whether to order the parts. Meanwhile, I unplugged and re-plugged the wiring to the "brain" located just under the top panel in posteriorly and it worked (for now). I also tightened the latch on the door (don't know if that is part of problem but it was slightly loose). My question is do you think that since this is an intermittent problem (not sure I really fixed it yet) that it is more likely a connection problem as opposed to the "motherboard" which I would think would either work or not (but I'm not sure that is true or accurate)? Is there an Electrical Engineer in the house?
