Dregs timer won’t reset

I can’t reset the empty dregs warning making the machine inoperable.

The obvious thing is the microswitch but I know it’s working, it’s just not doing what it’s supposed to do.

when I put the machine into service mode and go the the inputs page, the dregs microswitch doesn’t change the dregs state from N to Y when operated but I know it’s working because the door state changes. I know the door switch works because with the dregs in, the door state changes.

know these are linked somehow even though they’re on a separate wiring loom.

what on earth is going on?? Any advice will be very welcome.
