Hi @donahporter
Here's the [https://www.manualslib.com/manual/1896438/Samsung-Wf210anw-Xaa.html#manual|Fast track troubleshooting guide] for the washer model that you selected.
The guide describes how to view the ''stored fault codes'' and also what each code means.
It also details how to enter the ''quick test mode'' and the ''service mode''.
Hopefully a start to find out what's happening.
