Troubleshooting Guide
Turn off the power before servicing the pump.
A. PUMP WILL NOT START
B. MOTOR OVERHEATS AND THE OVERLOAD TRIPS OUT
Cause of Trouble How to Check How to Correct
1. Blown fuse. Check to see if fuse is ok. If blown, replace with fuse of proper
size, (see page 1).
2. Power off. Try lights on same circuit. Contact power company.
3. Loose, broken, or incorrect
wiring.
Remove plate. Check wiring circuit
against diagram. See that all
connections are tight and that no
short circuits exist because of worn
insulation, crossed wire, etc.
Rewire any incorrect circuits as per
wiring diagram.
4. Faulty pressure switch. Check switch setting. Examine switch
contacts for dirt or excessive wear.
Adjust switch settings. Clean contacts
with emery cloth if dirty.
5. Tubing to pressure switch
plugged.
Remove tubing and blow through it. Clean or replace if plugged.
6. Impeller or seal. Use screwdriver to try to turn
impeller or motor.
If impeller will not turn, remove
housing and locate source of binding
or return pump.
7. Defective motor. After checking steps 1 through 6
(and external wiring is ok) motor is
defective.
Return pump if still under warranty.
Cause of Trouble How to Check How to Correct
1. Motor wired incorrectly. Check motor wiring diagram. Reconnect for proper voltage as per
wiring diagram.
2. Inadequate ventilation. Check air temperature where pump is
located. If over 100° F, overload may
be tripping on external heat.
Provide adequate ventilation or move
pump.
3. Prolonged low pressure
delivery.
(Such as sprinkler systems.)
Continuous operation at very low
pressure places heavy overload on
pump. This can cause overload
protection to trip.
Install Red Jacket Hydrovervant I
valve on discharge line and throttle
to reduce flow and increase pressure.
4. Incorrect line voltage. Check line voltage to pressue switch. If voltage is under recommended
minimum, check size of wiring from
main switch on property. If ok,
contact power company.
