Just to add to my list of jobs to do this weekend (sigh!) the washing
machine decided to trip out the RCD on my distribution board mid-wash a
short while ago.
Obviously a genuine fault as its reproduceable every time I plug the machine
back in, but I noticed it doesn't trip the second the machine is plugged in
as a hard cable fault might - it's more like 4-5 seconds after, during which
there are the normal power/cycle indications.
Sticking my DMM across live and eth at the plug, I'm getting a reading which
toggles between about 4K ohms and 1.4M ohms every second. Any ideas what
might be at fault?
