9. TROUBLESHOOTING

Mechanical

Problem
Harmonics, or whining noise
Heater going on and off with
Water SW Open indication on
LCD or in Fault History
Valve opens but no flame visible
Flame visible for a split second
Liming or scale forming in
exchanger
Sooting
Yellow lazy flame
Outer jacket very hot (paint
blistered)
Hard lighting at startup
Takes too long to heat pool or
spa
Leaking at T&P gauge
Leaking at heat exchanger
Gasket brittle and leaking -
(overheated)
Combustion fan not running
"Fan 5 min Delay",
"Fan Lockout" or "Fan RPM
Fault" indication
Heater turns on for less than 4
seconds (no display error)
* Indicates symptom which usually occurs on initial start-up.
Cause
*Debris or restriction in system
*Debris in gas line
Low flow
Dirty filter
Low water level in pool
External bypass setting out of adjustment
Manifold pressure too low
Ignition not being sensed
Pool water
Bypassing too much water
Low water temperatures.
*Air starvation
*Improper venting
*Insects or debris clogging burner intake ports
Air intake clogged or incorrect fan operation
*Insects or debris clogging burner intake ports
Air intake feedback to regulator disconnected
*Broken refractory caused by shipping damage
or improper combustion
Excessive sooting of heat exchanger
Igniter faulty
Under-sized heater
Filter not running long enough
Dirty filter
Gas line or meter undersized
Overacid
Overacid
Refractory damage
Sooted heater
Fan relay
Fan
Burned motor
Motor control failure
Wiring
Incorrect supply wiring
PC Board short
Ignition not sensed
IMPORTANT NOTICE These instructions are intended
for the use of qualified personnel who are specifically
trained and experienced in the installation of this type
of heating equipment and related system components.
Installation and service personnel may be required by
some states to be licensed. Persons not qualified shall
not attempt to install this equipment nor attempt repairs
according to these instructions.
Locate the restriction and remove. Flush system and clean.
Remove debris or blow out gas line.
Scale forming in heat exchanger-clean heat exchanger and using deliming kit (016281F)
and check pool pH and total alkalinity
Clean or replace filter.
Raise water level.
Adjust bypass
Increase manifold pressure (turn clockwise slightly).
Replace ignition wire. Check connections. Increase manifold pressure (turn clockwise
slightly).
See "Water Chemistry" on page 5.
Inspect bypass for movement, if no movement, replace.
Maintain water body temperatures above 50ºF (10ºC).
Refer to installation instructions.
Follow recommended installation instructions.
Clean burners with a gentle application of compressed air, do not use a brush.
Check for debris upstream of fan intake. Check intake air filter suction pressure, replace
filter if dirty.
Clean burners with a gentle application of compressed air, do not use a brush.
Check that tubing between air intake adapter and regulator is connected and free of
obstruction. See Figure 45.
Replace refractory panels.
Determine cause of sooting & correct.
Replace igniter
Calculate heating capacity of heater or refer to heater sizing chart.
(Heating Capacity = Htr. output (BTUH) ÷ Pool gallonage x 8.33)
This does not take into account heat loss due to weather.
Reset time clock.
Clean filter.
Refer to installation instructions.
Replace T&P gauge and maintain proper water chemistry.
Replace heat exchanger and maintain proper water chemistry.
Replace refractory.
Determine cause of sooting and correct.
Replace fan relay.
Loose connection or failed motor.
Incorrect wiring, replace blower.
Replace blower.
Check for loose or broken (verify continuity) wiring/ground/ignition wire.
Check incoming power for correct voltage. There should be no power on the neutral line.
Replace board if no strength signal is being detected.
Clean igniter with wire brush.
