Subject washer will start to fill, then stops and displays the error msg. SUD
Washer will work ok if cold water is selected.
Think it’s either a bad water temperature sensor, or a bad heater/heater relay.
This is a 2 year old washer and could only find info on a WFW9600TC00
A service manual/job aid is needed, but can’t find one.Also, sometimes it will display the msg. F35 which calls for replacing the steam switch.
Hope someone has seen this before.
I do not know if you saw this but ir seems to sddress your problem
