In most cases, the remote will be installed at the tub, and hardwired back to the control panel through tubing. Many spa side controls will be linked up with a remote, so you can still access the control system while in the tub. This is known as a spa side control panel. If you have a tub that was built from the ground up, the controls will be housed with the rest of the spa equipment. The buttons control the functions and the screen communicates to the user what current function is being carried out.īoth digital and analog panels exist, and they’re designed to work only with specific control boards. It consists of a small screen outfitted with LEDs or LCDs, with various buttons and indicators covered in an overlay. This is known as a topside control panel. It handles everything from the main power, to the spa jets, and even things like the lights and music.Ī standalone hot tub has the control panel built into the top of the tub. The hot tub control panel is a functional display system that operates all your tub’s features.

How To Fix A Hot Tub Control Panel (Troubleshooting).

For most users this often would require a service call, although if you are ok reading a wiring diagram or take some good pictures, it is a fairly easy job. Solution: Replace board, we always recommend replacing the entire board since it is very easy to ruin a board by trying to desolder and replace the capacitors, it can be done, but it is much more reliable to just replace the part. It seems like cold weather or being shut off for a while (circuit board cools) are when capacitors really cause the watchdog error. Then ends should be perfectly flat and if they have a swollen appearance they are bad and can cause the watchdog error.

Bad capacitors on circuit board, many capacitors supplied in electronics in the early 2000’s suffered from capacitor plague, this is often fairly easy to diagnose since you can visually inspect the capacitors and see if they have and “bulge” to them, they are usually located near the center of the board and kinda look like batteries soldered onto the board.

Good eyesight is useful as two of the connections are very small. Keep in mind this sheet was written for the “curled end” sensor. We have an instruction sheet that explains how to do this since it is an easy process, we have many clients that perform it themselves. There are different wire ends on the different sensors used through the years, the three different types can be found here. (this can be very quick, this is why it usually needs two people) What the person is looking for is the temperature to display a very high temperature, usually over 110 degrees before it kicks to watchdog, if you see this behavior you most likely need a new temperature sensor. When power is applied the person standing at the spa is looking for a reading of the temperature before the display goes to all dashes. One easy way to sometimes confirm this part has failed is as follows: Have one person stand at the power for the spa, another person will stand at the spa control panel.

Bad temperature sensor, this is a relatively cheap part that can fail over the years.

Perform the “Bad temperature sensor” test below since a temperature sensor is much cheaper than a circulation pump.

If the circulation pump is the problem they are easy to replace, make a note if you need a 120v or a 240v, pump will have a label with voltage. Remember 2 years is an average filter life. Solution: Remove filter (and any large debris) completely and run hot tub for a couple minutes, if problem resolves it may be time to deep clean your filter, or may be time for replacement. A failed or underperforming circulation pump should cause a FLO or FL1 error, but in some rare cases a bad flow switch will not report and your first clue something is wrong is the watchdog error (-). If you see no other errors, or the watchdog error shows very quickly, move to other reasons. In some less common situations a failed circulation pump can overheat (pump gets very hot to the touch) and the heat will transfer up into the heater and cause it to overheat. This cause will likely take 20-40 seconds to cause the watchdog error, and should show you other errors before kicking to watchdog, like FLO or OH.

Temperature overheat, a dirty filter or low flow conditions.

This allows ample time for the board to get a full reboot. Solution: Try turning off the spa for 1-2 minutes, then reboot. Bad boot up sequence or power fluctuation, this can be caused by a small “brown” out, or just unclean non-solid power.This error can be caused most commonly by any of the following things. When a spa enters watchdog mode it will not leave without a full reboot.

This error message on a Sundance Spas made tub is called the watchdog error.
