we had wand plug up, well, we still do.
the first time or two we were able to "soak" it loose. Filled tank, let set over night, drain.
but, that made us VERY nervous, as we do not care to fill those tanks like that, in our opinion, it is just inviting issues with leaking tanks. Our take, our paranoia! LOL
So, we just put up with a plugged wand, flush with a bit more water, lots less paper (you know my cry, more water, less paper, repeat as necessary, frequently).
Dump about ever 2 to 4 days, start again, more water, less paper.
I believe that wand stuff can be replaced?? We are too lazy to mess with it.
Good luck.
