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:

  1. label each wiring harness so I knew the order they were connected to the control boards ( I think that there were 3 in total )
  2. pull off each wiring harness from the control boards
  3. remove each control board
  4. 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 )
  5. reinstall control boards
  6. 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!?
