Why does my Vario not draw water?
Unscrew your Vario, remove the ceramic prefilter disc from the filter housing and clean the prefilter with the cleaning pad that was packaged with your filter. Put the cleaned ceramic prefilter disc back onto the filter housing in LONGER LIFE or FASTER FLOW setting. Holding the pumphead in your hand, immerse the input hose in water and pump the unit (still without the filter housing) a couple of times until it draws water. If it does not draw water, turn the pumphead upside down, fill the inside partially with water, and pump a few times to “prime” the pump, making sure that the input hose is still immersed in the water. As soon as your Vario draws water again, reassemble it and continue pumping normally. If it still does not draw water, check the o-rings on both pistons (2 o-rings per piston). The o-rings should not be brittle or damaged and need to be lubricated at all times.
