looking for a bit advice. Brothers washing machine was playing up so went for a quick look. It’s making a lot of noise and he’s not used it since it first occurred. Had a look inside but I’m no expert. Told him to get an engineer and went to isolate it electrically and by water. Anyway when I touched the washing machine isolation valve I got a shock. I then checked the taps,pipework and machine chassis. All had 110v. With the machine disconnected everything seems fine. I know there’s is a serious issue with the machine but I’m more concerned why the fuse board didn’t trip. It’s a new build and it’s just outside the 2 year warranty. What should be his next course of action? Should the builder rectify it. Thanks.
