Inspired by the
Electric Shock thread, I wonder if people on this forum would know about household electric stuff (I have great respect for 230VAC stuff and only play with < 12VDC).
So anyway; sometimes when I shower while the dishwasher is connected to (230VAC) mains and touch the hot/cold nob, I can feel quite a tingle. The DMM can pick-up around 35-45VAC. I say sometimes, because it's not always reproducible for me, which is why I have not called anyone yet but just disconnect the dishwasher when I don't use it.
I do wonder what could possible be going on though. I'm fairly confident the problem is isolated to the dishwasher. I'm also fairly confident that the grounding connections are in order all the way from the machine back to where mains enter my house (I inspected all plugs and switches).
So I guess my question is; should this be happening if my grounding is in order (get a new dishwasher) or is there by definition an issue beyond the dishwasher (faulty grounding). I suspect the last case is the correct one, so perhaps the grounding speer outside my house, in the ground, is covered in rust or so and only works properly when the soil is wet (which could explain the sporadic nature, not always being reproducible).
I should mention, I live in Denmark where 230VAC@50Hz is used, and house installations consist of 10A fuses and residual-current fault devices (I can only assume, mine doesn't trip because it's an older kind and/or the current is too small). How would you go on "debugging the issue"? Any hints appreciated.
