I have a fused spur switch in my kitchen with a dishwasher attached. Recently the dishwasher stopped turning on, so I removed it from the bay and noticed two things.
- The neon light is quite dim.
- When turning on the dishwasher (which never appears on), the neon light seems completely unlit. I have uploaded a video to youtube demoing this behaviour.
The dishwasher has been working for the last six months without fault so far.
It is a UK 240V (50Hz) wired house, but presumably whatever electronic engineering principals would apply to this circuit generally.
What would cause this?
