My washing machine has just stopped with the error code E66. From having a hunt round on the internet it looks like it's the heater relay. I've sourced one, but I'm not sure where it's located in the machine. I figured that if it's a relay, it should be a case of unplug the faulty one, and plug in the new one, so I could do it myself. I can't find a wiring diagram to help, so I was wondering if anyone could help? Many thanks
