Probable Causes

Corrective Action

Plug in the pump.
Turn on circuit breaker or replace fuse. Ensure circuit breaker or fuse is
of correct rating for the pump.
Clean float.
Clean float movement path. Remove any debris or obstruction.
Disconnect switch, check with ohmmeter.
Open reading: infinitive resistance, closed reading: zero.
Have pump serviced by authorized service center.
Check the function of the (1PH) Start Capacitor, Run Capacitor, and
Relay. Replace faulty component as needed.
Check float movement path. Remove any debris or obstruction.
Disconnect switch, check with ohmmeter.
Open reading: infinitive resistance, closed reading: zero.
Shut power off for approximately 1 minute, then restart. Repeat several
times to clear air from pump. If system includes a check valve, a 3/16"
hole should be drilled in discharge pipe approximately 2" above dis-
charge connections.
Multiple or larger pump required. Refer to Capacity sizing.
Check control wiring.
Check rated pump performance table.
Pull pump and clean.
Shut power off for approximately 1 minute, then restart. Repeat several
times to clear air from pump. If system includes a check valve, a 3/16"
hole should be drilled in discharge pipe approximately 2" above dis-
charge connections.
Check flow indicating arrow on check valve body to insure it is installed
properly.
Remove check valve and inspect. Clean if necessary.
Check the function of the (1PH) Start Capacitor, Run Capacitor, and
Relay. Replace faulty component as needed.
Check rated pump performance.
Check that supply voltage matches nameplate rating.
Pull pump and clean. Check pipe for scale or corrosion.
Switch any two of the power input wires.
Replace worn impeller.
Check the function of the (1PH) Start Capacitor, Run Capacitor, and
Relay. Replace faulty component as needed.
Install a check valve in the discharge line.
Inspect check valve for correct operation.
Install larger basin.
Clean pump.
Clean float movement path. Remove any debris or obstruction.
