Troubleshooting Chart
Symptom
Possible Cause(s)
Motor does not
1. Disconnect switch or circuit breaker
start
in OFF position
2. Fuses blown or thermal overload open
3. Locked motor shaft
4. Motor windings burned out
5. Defective starting switch inside sin-
gle-phase motor
6. Disconnected or defective wiring
7. Low voltage
Motor does not
1. Low voltage
reach full speed
2. Motor windings connected for wrong
voltage on dual voltage model
Motor overheats
1. Low voltage
(protector trips)
2. Motor windings connected for wrong
voltage on dual voltage model
3. Inadequate ventilation
Pump does not
1. Pump is not primed
deliver water
2. Closed valve in suction or discharge
line
3. Leakage or air into suction system
4. Impeller clogged
Low pump capacity
1. Valve in suction or discharge line
partly closed
2. Suction or discharge line partly plugged
3, Suction or discharge line too small
4. Pump running at reduced speed (see
previous)
5. Plugged basket in skimmer or hair
and lint strainer
4. Lift strainer basket away from the
pump.
5. Clean and reposition the basket
into the pump. Take care to seat
the basket properly.
6. Clean the o-ring and relubricate

WINTERIZING
Always protect system from freezing
temperatures. Drain the system if there
is a possibility of freezing. To drain the
system:
1. Units with a filter:
a. Sand filter: Backwash for 3 to 5
minutes and then set dial valve to
winterize position.
b. Cartridge filter: Clean the filter
element and store in dry area.
2. Drain system by loosening drain
plug. The drain plug does not have
to be completely removed.
Removing pipe caps will facilitate
draining also.
Possible Cause(s)
6. Dirty filter
7. Impeller clogged
8. Wrong rotation (3 phase only)
1. Pump running at reduced speed (see
previous)
2. Wrong rotation (three phase models
only)
3. Discharge valve or inlet fittings
open too wide
1. Discharge valve or inlet fittings
closed too much
2. Return lines too small
3. Dirty filter
1. Plugged basket in skimmer or hair in
lint strainer
2. Worn motor bearings
3. Valve in suction line partly closed
4. Suction line partly plugged
5. Vacuum hose plugged or too small
6. Pump not supported properly
Shaft seal requires replacement
1. Leakage of air into suction line at
connections or valve stem
2. Cover gasket around hair and lint
strainer needs cleaning
3. Restriction in suction line
4. Low water level in pool
