What to do if Star PowerFlush Optima S1202 pump will not shut off?

If the Star Toilets pump won't shut off, it could be due to several reasons. Debris might be under the float, in which case you should remove it. Also, the float "Off" point might be adjusted too low, so try raising the lower float stop. The pump may be air locked, so ensure the vent hole in the discharge pipe is clear. If waste material has accumulated, blocking the flow, hold the flush handle down for 15 seconds. If it still won't clear, unplug the unit, wait 30 minutes, plug it back in, and repeat. If the unit still won't turn off, it needs to be opened and the debris relocated. Another reason might be that the water level is too low, in that case you should raise the lower float stop.
