I assume you mean the rubber O rings inside the wand. I had to replace mine as well. I had to visit several plumbing supply stores to find one that fit. I ended up taking the end of the wand with me so I could make sure the O ring fit. The ring you are after is a number 5, but you need to make sure it is thick enough to make a good seal.

I would guess there is a leak somewhere inside the unit that is spraying water on some electrical component and causing a ground fault.
