Thanks very much for your reply, he did test it somehow as I heard it spinning, he said that it was all fixed but then it didn’t work when I reattached the water. A previous person checked the lock and said it wasn’t the issue but that was my first thought too. The door won’t open now since he’s been, unless I force it to by using the tag. I’ve also drained out the filter. Going a bit mad here, I’m happy to get my hands dirty but don’t know where to start.
