just something else to check..
i dont think that matters. i open both up, either order, then plug her in, works fine.lighthouse39183;3016921; said:You have to be sure to turn the intake valve back on first also after refilling. I had this problem once when I turned the out put valve back on first. I don't know what difference it makes but in the manual it states to turn the input valve back on first or the filter will not fill back up properly.
