ECO-5 / 6100 Identified Problems
Spa Is Not Heating!
If the Heater On
indicator does not
illuminate:
·
With an accurate thermometer,
measure the temperature and compare
your reading with the temperature value
displayed on the spaside control.
·
If the values are different (
±
2
°
F),
check to make sure the sensor is
properly inserted into the dry-well or if
hot air is affecting its readings. If so,
insulate the back of the sensor.
·
If the problem still exists, replace the
temperature sensor with a spare one.
·
If the spa is still not heating, replace the
printed circuit board.
If the Heater On
indicator does
illuminate:
·
Open the access panel on the control
box and measure the voltage between
P10 and P17 at the system circuit
board. Replace the printed circuit board
if you are not getting a reading of 120
VAC.
·
If the voltage reading is good, measure
the voltage at the heater relay between
the NO (normally open) terminals
connecting the heater wiring to the
heater element. Replace the relay if you
do not get a reading of 120 VAC.
·
If voltage reading is good, verify that the
nuts securing the heater wiring to the
heater element are secure. If not,
tighten the nuts at the element. If the
problem has not been solved, replace
the element.
