How to fix a blocked motor piston in a Dosatron Water Pump?
If the motor piston of your Dosatron Water Pump is blocked, bleed the dosing pump by opening the clear water and fast priming valves situated downstream and upstream of the Dosatron. Then, dismantle the top cap to access the motor piston. Test the motor piston by hand. Activate the valve mechanism by pressing the vertical pushbutton until you hear the valves switch on.
Why is the motor piston not working in my Dosatron Water Pump?
If the motor piston of your Dosatron Water Pump is not working, first check your water inlet for issues such as no water consumption, supply failure, a clogged filter, or improperly positioned Dosatron By-pass valves. Open the rinsing/fast priming valve downstream of the Dosatron to test the water supply and the operation of the dosing pump. Also, make sure your installation has sufficient minimum pressure. If the water flow is very low, the Dosatron motor may require several minutes to complete a full cycle.
What to do if there is air in my Dosatron Water Pump?
If there is air present in your Dosatron Water Pump, bleed the air using the bleed valve found on the top cap. This is especially useful under extremely low water flow and pressure conditions.
