Troubleshooting the Pump:

Motor does not run:

Check for loose wiring connection(s).

Make sure the 'ON/OFF' switch in the lead wire assembly
is in the 'ON' position. "I" is the 'ON' position and 'O' is
the 'OFF' position.

Check for defective pressure switch. Make sure you are
connected to a good 12 volt power source. Make sure
any on/off switches are in the 'on' position. Remove the
cap to the pressure switch. Pull both red wires off of their
terminals, and touch the two ends together. If your pump
runs when you do this, your pressure switch will need to
be replaced.

Check the fuse.

Check for low voltage at the power supply.
Pump does not prime:

Check for air leaks in supply line.

Check for debris in the check valve assembly.

Check for defective check valve.

Low Pressure/Low Flow:

Check for leaks in the discharge line.

Check for restriction in the discharge line.

Check for debris in nozzle orifice.
