Jacuzzi J - 480 User Manual

Page 74

There are a number of unique functions designed into your Jacuzzi spa 

to protect it from damage and/or to aid in troubleshooting. When an error 

occurs the spa will notify you by showing the screen below and an error 

code next to it. Following is a listing of all the possible messages along 

with their meanings:

1. 

Overheat protection: (Heater is deactivated, filter/circulation pump is 

activated). Water temperature is above acceptable limits. 

enTer THe waTer! Remove spa cover to speed cooling. See 

“Water Is Too Hot” on page 79. If condition persists, contact your 

authorized dealer or authorized service center.

2.  Water is below set-temp: If the spa water is more than 20°F/6°C 

cooler than the temperature set point, the circulation pump and 

heater will automatically activate to provide freeze protection. The 

spa will stay in this mode until the water temperature reaches 

15 degrees below the set temperature. No corrective action is 

necessary.

3.  Communication error: Communication between the control panel and 

circuit board is faulty. If condition persists, contact your authorized 

dealer or service organization.

4.  Pump does not operate: Proper flow of water is inhibited or a flow 

switch has malfunctioned. Check for proper water level and for 

clogged filter (page 67). If no sound is detected or if a “buzzing” 

sound is detected, turn off power to the hot tub. Pump may not be 

properly primed. If condition persists, contact your authorized dealer 

or service organization.

5.  Freeze protection: A potential freeze condition has been detected. No 

action is required. Jets pump(s) and heater operate until the spa is out 

of danger. Depending on the amperage provided, operation will be as 

follows:

In 60A or 20A (50Hz only) logic, the heater remains on at all 

• 

times, while pump 1 and pump 2 turn on for 10 minutes and then 

off for 10 minutes. The pumps will alternate on and off until the 

spa gets out of the freeze condition.
