Spa does not run, no power, nothing works.
- Input Wiring
- High-limit switch
A) Check incoming power for proper
potential (voltage: 110 or 220vac). Check circuit breaker.
Do not continue until power checks correctly.
B) Test and reset
GFCI. If GFCI does not
stay set, disconnect all loads from control (pump,
ozonator, etc). If
GFCI still does not stay set, internal wiring is shorted or GFCI
is faulty. If GFCI remains set, reconnect each load until GFCI
trips again. Last load connected must be cause of failure
(remember that some devices will not operate without others,
i.e. heat will not engage without the pump).
C) If GFCI tests and resets, check
fuse.- If fuse blows again,
disconnect all loads as in step B). If fuse continues to blow
there is an internal wiring problem. If fuse remains good,
reconnect each load one at a time until failure reoccurs as in
step B). Remember to turn each device on before proceeding to
next load device. Last unit connected before fuse fails must be
D) If Steps A) through C) check good but
the unit still will not power up, check the voltage at the high
(line side contact voltage, coil voltage, load side contact
voltage). If line side contact voltage is bad, check input
terminal block connections (check also for proper jumper
placement on newly-installed convertible voltage control
systems, if unit is running 110v). If coil voltage is bad, check
high limit switch
is set. Reset if tripped. If problem reoccurs, check
manifold. (make sure
heater element is not touching the sides of the manifold.
If it is, move element away from manifold with long screwdriver.
Make sure power is disconnected). Inspect valves to make sure
they are fully open, inspect filter element (run unit without
filter if possible to see if symptoms change). If previous
checks show good, replace high limit. If both line side contact
voltage and coil voltage check good, but load side contact
voltage is bad, replace high limit contactor.
E) If Steps A) through D) check good,
internal control system wiring or circuit board is at fault.
Repair or replace.
