I have the unit at home, and have removed the anode. There is just a thin iron rod remaining, the Mg has all been converted to a relatively soft white oxide/carbonate. There was some rust around the nut and tank next to it, so it appears that it had been leaking slightly.

About 4 years ago I thought I would replace the anode, but could not find it. It was not where the downloaded manual said it would be. It turns out that the anode in this 20 yo model is in the top of the tank, and the top cover and insulation have to be removed to access it.

I did have the yard convert it from 120VAC to 240VAC 6 years ago, using a kit from Torrid. But I don't know whether or not the anode was replaced at that time.

Next I need to remove the element and heat exchanger. The latter is a 2" fitting which so far is refusing to loosen.

I flushed the tank via the outlet/inlet nipples and a quantity of fine brown sediment came out, which is not particularly encouraging for what the inside will look like.
