ELECTRICAL PRECAUTIONS-
Before servicing a pump, always shut off the main power breaker and then unplug the
pump - making sure you are wearing insulated, protective sole-shoes and not standing in water. Under flooded conditions, contact your
local electric company or a qualified licensed electrician for disconnecting electrical service prior to pump removal.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions.
Allow 2½ hours after
disconnecting before attempting service.
If the above checklist does not uncover the problem, consult the factory. Do not attempt to service or otherwise disassemble pump.
Service must be performed by Zoeller Authorized Service Stations. Go to www.zoellerpumps.com/servicestations to find the Authorized
Service Station in your area.

CONDITION
COMMON CAUSES
A. Pump will not start or run.
Check fuse, low voltage, overload open, open or incorrect wiring, open switch, impeller or seal bound
mechanically, defective capacitor or relay when used, motor or wiring shorted. Float assembly held
down. Switch defective, damaged, or out of adjustment.
B. Motor overheats and trips over-
load or blows fuse.
Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechani-
cally, defective capacitor or relay, motor shorted.
C. Pump starts and stops too often.
Float tight on rod, check valve stuck or none installed in long distance line, overload open, level
switch(s) defective, sump pit too small.
D. Pump will not shut off.
Debris under float assembly, float or float rod bound by pit sides or other, switch defective, damaged or
out of adjustment.
E. Pump operates but delivers little
or no water.
Check strainer housing, discharge pipe, or if check valve is used vent hole must be clear. Discharge
head exceeds pump capacity. Low or incorrect voltage. Incorrect motor rotation. Capacitor defective.
Incoming water containing air or causing air to enter pumping chamber.
F. Drop in head and/or capacity
after a period of use.
Increased pipe friction, clogged line or check valve. Abrasive material and adverse chemicals could
possibly deteriorate impeller and pump housing. Check line. Remove base and inspect.
