V. SPA WILL NOT HEAT TO DESIRED TEMPERATURE

NOTE that the pump needs to be operating on LOW SPEED for the heater to come on. If the pump does not operate, refer to items I and II.

1.Pump operates on low speed and there are no diagnostic messages shown on the display.

Cause:

Temperature is set too low

Solution:

Set the temperature higher. The spa water temperature will rise about 2 degree F. per hour depending on the season and if it is indoor or outdoor. Allow enough time for the spa to reach the desired temperature. Maximum allowed temperature is 104F.

Cause:

Spa cover is improperly positioned.

Solution:

Your spa needs to be covered properly if it is to heat properly, especially outdoors in cold climate.

Cause:

Filter cartridge could be dirty and restricting the water flow intermittently. The diagnostic message "FLO" will appear when this happens but you might not see it because it is intermittent.

Solution:

Remove the filter cartridge and clean as outlined in "Filter Cartridge Removal and Clean Up" page 13. If this does not solve the situation, call Service Center for assistance and mention the code "LOW HEAT-1"

2.Pump operates on low speed and there is a "FLO" diagnostic message: "FLO" indicates a low water flow or pressure condition resulting from an obstruction in the plumbing. Note that the heater is disabled for safety during that condition.

Cause:

Obstruction in the plumbing.

Solution:

a. Remove the filter cartridge and clean it. See instruction on page 11 If the condition persists, there could be an

obstruction in the impeller of the pump. This condition could happen if the spa is operated without a filter cartridge. It is important to follow the "Filter Cartridge Removal and Cleaning" instruction of turning the spa off when removing the filter. Objects up to 1-1/2" in size could be sucked through and obstruct the line or pump impeller.

b. Unplug the therapy module, lift it from the spa and inspect the plumbing by opening the unions for blocking materials such as hair, leaves, string, plastic bags, etc.

c. If no blocking objects were found and the FLO message still shows, there could be a defective or out-of-calibration pressure switch. Call Service Center for assistance and mention the code "FLO-1"

3.Pump low or high speeds do not operate and there is a "FLO" message. Call Service center for assistance and mention the code "FLO-2".

4.Pump operates on low speed and there is a "LS=0, LS=S, SS=0 or SS=S" diagnostic message. This indicates a non-functional water or High Limit temperature sensor. Call the Service Center for assistance and mention the code indicated.

VI. NO WATER FLOW AT JETS AND THE PUMP IS OPERATING.

Cause:

Loss of prime in the module

Solution:

Prime module by following Priming Instruction on page 10. (Check the pump unions to make sure they are not loose.) If this does not solve the problem, call Service Center for assistance and mention code "NO FLOW-1"
