Troubleshooting Display Messages - Jacuzzi J-480 Use, Installation And Maintenance Instructions

Sanitizing
To destroy bacteria and organic compounds in the water, use a
sanitation product regularly, available from your dealer.
Your Jacuzzi spa is equipped with a special compartment built
into the floating skimmer to hold sanitizing tablets.
CAUTION: Do not use chlorine tablets (Trichlor) in your
spa: this chemical can have an extremely corrosive effect
on certain materials in the spa. Damage caused by use
of this chemical, or improper use of any chemicals, is
not covered under the spa's warranty.
Ozonator (optional)
If you have elected to have your spa equipped with the ozone
system, you will find that your water stays fresh and clear with
significantly less chemical sanitizer usage.
Troubleshooting
Display Messages
There are a number of unique functions designed into your
Jacuzzi ® Premium spa to protect it from damage and/or to aid in
troubleshooting, which are signalled by messages on the display:
MESSAGE "OH"
Overheat Protection (Heater is deactivated, circulation pump
is activated).
I
Spa water temperature is above acceptable limits.
Do not get into the spa, the water may be too hot.
I
To correct the situation:
- Remove the spa's cover and allow your spa to cool down.
- Set the spa to "Economy" mode, so that the heater is activat-
ed only during filtering cycles.
- If the condition persists, contact your retailer.
MESSAGE "COOL"
If the spa water is more than 7 °C cooler than the temperature
set point, pump 1 and the heater will automatically activate to
provide freeze protection. The spa will stay in this mode until the
water temperature reaches 9 °C below the set temperature.
I
No corrective action is required.
MESSAGE "FLO"
FLOW SWITCH (Heater is deactivated; recirculation pump
may also be deactivated).
Proper flow of water is obstructed or a flow switch has mal-
functioned.
Check for proper water level and for a clogged filter cartridge.
I
Contact your dealer or service center.
N.B.: THIS MESSAGE CAN ALSO APPEAR IF THE PUMP
HAS NOT BEEN PRIMED AFTER THE SPA HAS BEEN
DRAINED AND REFILLED. IF YOU SUSPECT THAT THIS
IS THE CASE, SEE THE INSTRUCTIONS ON SECTION
UNDER "PUMP DOES NOT OPERATE..."
MESSAGE"HOLD"
Keyshave been pressed too many times in a short period of time.
I
Keys will automatically re-activate if no sensor is pressed for
30 seconds.
MESSAGGE "HOT"
The temperature of the electronic card has exceeded accept-
able limits. This message will disappear when the tempera-
ture of the card drops below acceptable limits. If the problem
persists, let the side of the spa that houses the electro-me-
chanical parts (pumps, box, etc.) cool off.
MESSAGE "ICE"
FREEZE PROTECTION
A potential freeze condition has been detected.
I
No corrective action is required. Pump(s) operate until the s-
pa is out of danger.
It is possible to turn off the pumps via the control panel. How-
ever, if after 2 hours freezing conditions persist, the pumps will
restart automatically.
N.B.: This error commonly occurs when the spa is first filled
because tap water is often very cold.
MESSAGE "PnL"
Communication between the control panel and/or remote con-
trol panel and circuit board is faulty.
I
Contact your dealer or service center.
MESSAGE "---"
A problem has been detected which could cause damage to
the spa or its components.
