Whirlpool Duet Front-Load Washer DL Problem
A tip from Randy, P.Eng
I have had real problems with the dreaded DL problem on my Kenmore HE3T frontload washer. I did LOTS of searching and found no real fixes, other than to replace the control unit door lock relays, then the control unit itself.
Replaced relays. Worked for a while, but problem recurred.
One site suggested a potential source of the problem, that the wiring harness didn't make firm contact with the control unit. It went on to suggest the control unit board be "thickened" by soldering a piece of wire on to each contact point.
AHHA! Simply tin each contact point with solder. Never failed since…
What I did was:
- label each wiring harness so I knew the order they were connected to the control boards ( I think that there were 3 in total )
- pull off each wiring harness from the control boards
- remove each control board
- tin every contact on each control board
( tin = heat contact slightly with soldering iron until solder flows onto contact, and add a little new solder ) - reinstall control boards
- reconnect wiring harnesses
This is a fix that should not be attempted by anyone not experienced in soldering electronic components.
A new tip from Richard
I've "fixed" this fault code 2x now by taking off the top lid,
exposing the wires etc. ( with the power plug disconnected )
and pushing in all the connectors that I see,
both on the door latch mechanism and where they end up.
The first time we got a new door latch, but perhaps we maybe didn't need it !
These machines sure shake a lot,
and perhaps the vibration loosens the connections!?
