Standard mode maintains the desired temperature. Note that the last measured spa temperature displayed is current only when the pump has been running for at least 1 minute. “St” or “Std” will appear on the display momentarily when you switch into Standard Mode.
Economy mode heats the spa to the set temperature only during filter cycles. “Ec” or “Ecn” will appear solid when the temperature is not current and will alternate with the temperature.
Sleep mode heats the spa to within 20 F (11 C) of the set temperature only during filter cycles. “Sl” or “SLP” will appear on the display until mode is changed.
Standard is the default setting, and you are in standard mode if none of the other setting codes show up.
The power saving alternative for regular heating, you will know that you are in economy by the code displayed.
Sleep is considered a vacation heater setting, and will maintain your spa water at the most affordable price.
If you have no power, the fuse is good and the breaker is not tripping you may have a problem with the breaker. Flip the switch down then to the up position if it seems to stay up and you still have no power going to the spa try pressing the test button on the breaker. If the test button is not causing the handle to flip down (some breakers the handle may only come partially down) you may have a faulty breaker and should call an electrician.
If you do not hear anything when the button is pressed the button may not be working.
There are two nuts above and below the straps. While loosening the top nut you must hold the lower nut steady to avoid bending the terminal post or damaging seals. Once removed, bend the straps up and turn on the power. A safer way to accomplish this is to remove the strap from the board and bend it back. If the breaker does not trip then the faulty part is the heat element, if not onto the next step. On the board find the wiring harnesses (white adapters with 3-4 wires in them) plugged into the board, use the diagram on the electrical box cover to locate the components.
Cut the power and remove pump 1 plug from the board then turn the power back on, if it does not trip then the pump has a short in it and needs replaced. If it still trips with pump removed, plug the pump back in and onto the next component. Follow the same steps until each plug has been removed and replaced and the spa is no longer tripping, the component that has been disconnected when the breaker does not trip is the faulty part. If everything has been disconnected and the spa is still tripping the breaker then the board or breaker is faulty.
Another method is to cut off power and disconnect each component then reconnect each part one at a time until the breaker trips. The part that causes it to trip is the faulty part, if everything is disconnected and it trips then the board has a short and needs replaced or the breaker is bad. Remember to cut power before removing any components. Also check is the GFCI cord or breaker by removing the .3amp fuse marked F4 on the diagram inside the cover of the control system. If the GFI does not trip with fuse or wires disconnected then the GFI cord or breaker is good.
