  ELECTRICAL PRECAUTIONS- Before servicing a pump, always shut off the main power breaker and then unplug the pump - making 

sure you are not standing in water and wearing insulated protective sole shoes. Under flooded conditions, contact your local electric company or a 

qualified licensed electrician for disconnecting electrical service prior to pump removal.

 Submersible pumps can become pressurized under normal operating conditions — allow 2½ hours after disconnecting before attempting service.  

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 

overload or blows fuse.

Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechanically, defective capacitor 

or relay, motor shorted.

C. Pump starts and stops too often. Float switch tether length too short, check valve stuck, or none installed in long distance line, overload open, switch defective.
D. Pump will not shut off.

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

E. Pump operates but delivers little 

or no water.

Check pump inlet, discharge pipe, and weep holes for obstructions.  System head exceeds pump capacity. Low or incorrect 

voltage. 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. Inspect pump inlet.

G. If 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 uncover the problem, consult the Product Support Department; do not attempt to service or otherwise disassemble 

pump. Service must be by Zoeller Authorized Service Stations.
