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, motor 

or wiring shorted. Float assembly held down. Switch, damaged or out of adjustment.

B.

Motor overheats and trips 

overload or blows fuse.

Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechanically, motor shorted.

C.

Pump starts and stops too often. Float switch tether length too short, check valve stuck open, or none installed in long distance line, overload open, bidding, 

sump pit too small.

D.

Pump will not shut off.

Debris under float assembly, float bound by basin sides or other, switch, damaged or out of adjustment.

E. Pump operates but delivers little 

or no water.

Check inlet, strainer housing, discharge pipe, and vent holes for obstructions.  Discharge head exceeds pump capacity. 

Low or incorrect voltage. Incoming water containing air or causing air to enter pumping chamber.  Incorrect motor rotation. 

(3 phase pumps only)

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.

G. Tank or fittings leak.

Carefully tighten pipe joints (use pipe dope) and screws. Check gasket location, tighten lid evenly. Do not over tighten 

fittings or screws.

If the above checklist does not reveal the problem, consult the Product Support Department.  Do not attempt to service or otherwise disassemble 

pump. Service must be peformed by a Zoeller Authorized Service and Warranty Center. Visit www.zoeller.com for a complete list of service centers.
