It's a top loader, so doesn't seem to have one of those things ...

Still haven't figured out how to get the back off it, and there's no page for our model on fix ya ...

I did some more googling etc, and also got out the owners manual ...

Also tried turning it on and off again, but leaving it off longer ... and that appears to have fixed it

My littlest bro, who loves the IT Crowd, would have a field day ...

About to put a proper load on again and see if it works
