I’m getting a DL code on washing machine
For model number WT8400CB
Hi Anthony, thank you for the question. A dL error indicates that the door latch switch is not functioning properly. We would suggest checking the switch assembly, part number PS18037016. You may need to replace it to fix the issue. We hope this solves your problem!
I found the pulsator just spun freely, I determined the hole on underside should ribbed to align with the ribbed shaft. But it was wore away. I purchased the new part and replacement was simple. It slide right on and I replaced the bolt. Pulsator works great, washing again.
Removed the center cover cap carefully on top of the agitator with a small screw driver. There are 3 (on mine) little slots around the edge of the bottom of the cap where it meets the agitator. Insert the small flat blade screwdriver and gently twist at each one till the cap pops loose and comes off.
There was a 10MM bolt under the cap on mine that you need to remove. I used an cordless impact driver but you could use a socket wrench as well. Remove the bolt and the agitator comes off. May take a little wiggling or it may come right off.
The teeth on the agitator were wore all the way down and gone on mine so it came off easy and this was the issue I had why it was spinning freely. I took the small flat blade screwdriver and used the edge and corner of the blade to clean the teeth on the shaft where the agitator attaches and wiped it down before installing the new part as there was quite a bit of metal shavings from the damaged part.
I just reversed the order of removal to install the new part. Took about 15 min. I ran a rinse and spin cycle to remove any additional metal shavings and to check to see if it all worked properly. THATS IT! TOO EASY!
