Jcb 531-70 electric seat possessed by demons

[Doing it for the kids]

For no apparent reason when using the machine the electric seat tries to start rising, compressor hums away, then it stops.

switch seems to work fine, any ideas?

tried to find the fuse but no luck yet!

It’s an auto inflate function to match your weight just give the handle a click up or down and it should turn it off

Hmm ok thanks, that suggested I’m getting lighter! Maybe the 3yr old wedged behind isn’t helping!?

is there a way to disable this function?!

Yes think a positive click either way stops it
