The wash temperature selection button behaves very strangely on my Duet Sport washer.
Pressing the "Wash Temp" button in a normal manner usually has no effect.
The behavior can be a little random, but usually if you hold it for a few seconds then release, nothing will happen for a few more seconds, then there will be a single beep and the wash temp indicator will cycle through all three wash temperatures in order maybe a half dozen times or so. Most of the time it stops one temperature "ahead" of the previous one, where you would expect it to stop for a single press. It is possible to select the temperature this way, and the operation of the washer seems correct for the eventual selected temperature, but it's a very annoying behavior.
I don't see any error codes appearing on the washer.
I'm assuming that it is likely either the user interface or the central control unit, but since they're both quite expensive I don't want to replace either unless I'm pretty sure it's the problem. Given the cost, I'd likely just live with the problem if I had to replace both to fix it. Anyone have any ideas on this or diagnostic suggestions? Thanks!
