WATER WON'T HEAT?
SIMPLE TROUBLE SHOOTING PROCEDURES


1. Make sure the circuit breaker is on. To reset the breaker, turn it all the way off, then turn it to 'ON' position. 220 v. units may be powered by two circuit breakers: one in the main service panel, and one in a sub panel located near the spa. Make sure that both of these breakers are reset.
2. 110 v. units plug into a receptacle. Check to see that the unit is plugged in. Most outdoor receptacles are protected by a GFCI (ground fault circuit interrupter). Push the RESET button (usually red) on the GFCI. Test the receptacle for power by plugging in a small appliance such as a lamp, radio, drill, etc. 110 v. spas are protected by a redundant GFCI at the end of the power cord near the plug. Press the reset button sharply and quickly release it. The amber light on the GFCI should remain lit.
3. Check to see that the line cords for each appliance in the equipment chamber are plugged into the control unit. There is a line cord for each pump, one for the optional ozone generator, and one for the light.

The slice valves (or shut off valves) in the equipment chamber must be open. Grip the white tee handle and pull it open so the stainless steel stem is entirely visible. (Turning the tee handle does not open the two or three valves).
5. The spa must be filled to the proper water level. Fill the spa to the level about ½" below the top of the fins on the skimmer-filter housing. If the water level is too low, the pump will suck air instead of water and the spa will not heat.
6. The pump must be primed in order for the spa to heat. The system must not be air bound. When filling the spa, remove the round cap and the filter cartridge(s) from the filter housing(s). Insert the garden hose directly into the filter housing and shoot the water down the hole at the bottom of the housing. Filling the spa this way will force the air out of the lines and displace it with water. When the spa is filled, restore power (see #1 and 2). Test for prime by turning the pump on high speed (JETS BUTTON). The jets should operate strongly and smoothly. If the jets are surging or if the motor is seizing up or if a 'FLO' symbol is indicated on the touch pad screen, try to prime the pump by turning it on and off a series of times, allowing it to run ten seconds, then shutting it off for five seconds before repeating the procedure. If you fail to fill the spa this way, it may be necessary to burp the system by loosening any of the threaded collars (unions) in the equipment chamber (counterclockwise) until the air lock is released and water begins to flow. Hand-tighten the unions and test for prime again. Turn off the high-speed pump by pressing the JETS button. Low speed pump will automatically engage. After a few seconds, the red 'HEAT' indicator on the touch pad will light. When satisfied, replace both the round cap and the filter cartridge(s). Set your temperature to the desired level and cover the spa. 110 v. units have only a 2° per hour rate of heat rise. If the starting temperature of the water is 70° (indicated on the LCD screen on the touch pad), the spa will need to run approximately fifteen hours to reach 100°. 220 v. units have a rate of heat rise of 4°-8° per hour depending on gallonage. 220 v. spas require 4-7 hours of running time to reach usable temperature. Press 'HEAT MODE' on the master touch pad until the standard mode or 'S+d' symbol appears on the screen. Then press the pink 'TEMP SET' pad to input the information and exit the routine. The factory default or pre-set temperature is 100°. Press the 'TEMP SET' pad to change the temperature setting to your comfort point.
7. It is imperative that your filter cartridge(s) be clean in order for the water to heat. A dirty filter will impede the water flow and shut down the heater. Clean the filter monthly by using the spray nozzle on your garden hose to thoroughly wash the dirt and debris from the cartridge. Replace the cartridge every 3-4 years. Make certain that the suction fittings near the bottom of the spa are clear of obstructions, leaves, etc., in order to allow for a free flow of water.
8. A good quality spa cover is an essential factor in efficient heating and in minimizing heat loss. Replace your spa cover when it becomes heavy or when the vinyl encasement is damaged.
9. If your spa is not heating or if it fails to maintain temperature, it is good practice to drain, clean, and refill the spa and clean or replace the filter cartridge to eliminate the most basic causes of the problem.
