Troubleshooting
PROBLEM
Pump does not turn on or off.
Pump does not deliver rated capacity.
Pump cycles continually.
Pump will not shut off.
NOTE: Before troubleshooting automatic
control, check to see that pump operates
on manual control. To do this create slight
vacuum on breather tube (near plug),
then close off tube with thumb, plug into
wall outlet. If pump works, proceed to
check switch; if not, fault is in pump or
power supply.
Pump runs but does not discharge liquid.
