TROUBLESHOOTING
GUIDE Ð PUMP

Read and understand safety and operating instruc-

tions in this manual before doing any work on

pump.
A. Pump does not operate:

1. Check GFCI (Ground Fault Circuit Interrupter) for

proper operation according to GFCI manufac-
turer’s instructions.

2. Check for blown fuses, circuit breakers, or discon-

nected electrical wiring.

3. Check for sand locked impeller. Disconnect power

to motor; follow pump disassembly instructions,
Page 11. Clean out sand from impeller and from
wear ring in front plate. Reassemble according to
instructions, Page 11.

4. Consult dealer/installer or service representative.

B. Motor runs, but does not pump water or pressurize

system:

1. Check to make sure all valves are open.
2. Check skimmer, trap basket, and piping for debris

or obstructions.

3. Check pump impeller for obstructions such as

hair, leaves, grass, or stones. Follow “Pump
Disassembly” instructions, under “Pump Service”
on Page 11.

4. Consult with dealer/installer or service representa-

tive.

C. Excessive air in system – pump loses prime:

1. Make sure water level in skimmer is at least 2”

above bottom of skimmer throat with system not
operating.

2. Make sure that there are no leaves in suction pip-

ing.

3. Make sure there is no vortex (whirlpool) at the

suction; add water to pool if necessary.

4. Consult dealer/installer or service representative.

D. Circuit breaker in home panel trips repeatedly:

1. Breaker must be of adequate capacity.
2. If breaker is a GFCI breaker, test according to

GFCI manufacturer’s instructions.

3. Be sure no other lights and appliances are on cir-

cuit.

4. Check wiring size leading to pump. (See Table III,

“Recommended Wiring Data” on Page 7).
Inadequate size wiring will cause overheating of
pump and excessive amp draw leading to circuit
breaker tripping.

5. Consult dealer/installer or service representative

TROUBLESHOOTING
GUIDE Ð FILTER

A. Short Cycle between backwashes:
NOTICE: 
Time between backwashes will vary with each
installation and between different areas of the country.
Ask installer about normal backwash interval in your
area. The following causes and remedies are for cycle
times shorter than normal for your area. 

1. Flow rate too high or filter too small; consult dealer

for system sizing recommendations. 

2. Water is chemically out of balance; consult pool

serviceman.

3. Excess dirt/dust in pool; vacuum pool directly to

waste.

4. Body oil/lotion build-up in filter; consult dealer for

chemical filter cleaners and follow cleaner manu-
facturer’s instructions.

5. Filter inadequately backwashed. See instructions

under “Startup/Operation”, Page 8.

6. Algae in pool. Consult pool professional about

proper chemical maintenance.

7. Residual chlorine level too low. Consult pool pro-

fessional about proper chemical maintenance.

8. Inspect filter sand for solidification caused by dust,

calcium, skin oils, of suntan lotions.

B. Low Flow:

1. Pipe blocked downstream from filter; remove ob-

struction.

2. Piping too small; use larger pipe (consult dealer for

sizing).

3. Plugged pump; plugged hair and lint trap or skim-

mer basket. Clean thoroughly.

C. Pool Water Not Clear:

1. Water is chemically out of balance; consult pool

professional.

2. Filter is too small; consult dealer about equipment

sizing.

3. Sand in pool means broken lateral. Drain both

water and sand out of tank. Remove valve; follow
procedure under “Filter Setup”, Page 6, and in-
structions with new lateral to replace broken part.

To avoid severe injury or major property

damage, follow instructions under 'Valve Installation',
Figures 6, 7 and 8, Pages 6 and 7).

1. Follow valve removal procedure, Page 10.
2. Replace lateral according to instructions supplied

with new lateral.

3. Reassemble filter according to instructions under

“Filter Setup”, Page 6
