Hello, This is a common problem and the board can be repaired. You might want to consider having it repaired and keeping it as a spare. Spa Board Doctor

Hello, You'll want to first check that the temperature sensor is pushed all the way in to it's thermowell. If the back of the sensor is positioned outside of the thermowell it may be sensing the ambient temperature of the cabinet and not the vessel temperature. It could also be a sticking or stuck on heater relay on the circuit board. This is a repairable failure. Spa Board Doctor

Hi, Keep it in continuous operation until you are satisfied that the problem has been resolved. My recommendation would be to replace the pump with an AquaFlo XP2 or Waterway EX2 pump with the same voltage and amperage as the original (230V 12.0/4.4A) as the LX pumps are, IMO, junky junk. brandon@spaboarddoctor.com

Hello, Attached are the high limit and temp sensor locations. You may also have a stuck or sticking heater relay on the board causing the heater barrel temperature to rise higher than the computer likes. This is a repairable failure. brandon@spokanespas.com

Hello, It seems like maybe the low pump may be dropping out sometimes. You should set the filtration timer to continuous operation i.e. 24 hour circulation and see if the problem goes away. Brandon

Hello, Is the "FLO" error solid on the display or does it flash between "FLO" and the current temperature? Brandon

Got it. I'll try to pay more attention to the dates. Thanks!

It sounds like the heater relay is sticking on sometimes. The "electric kettle" noise on boot is water boiling in the heater manifold before the pump turns on. Vice versa, after tub is up to temp and pump shuts off, heater stays on. Another possibility (now that I see the condition of the heater studs) is that the element has a pinhole or fracture in it's coating and is conducting to ground through the surrounding water via line 2 from the high limit. This is a dangerous condition if the GFCI is not functioning or not present. Do not enter or touch the water until you have a qualified technician address this issue. spokanespas

Good eye ciderjack! The cap kit is available on ebay - search for "Sundance Spas capacitor set". Repair available from yours truly. spokanespas.com

Not Artesian but Balboa. We don't repair spasides other than cord end plugs and overlays. spokanespas.com

Sounds like low water level. spokanespas.com

The replacement control's heater wattage must be compatible with the type of pump being used. If you post some pics of the equipment maybe we can get to the bottom of the flow issue. spokanespas.com

I've warranty replaced at least a half dozen of their latest touchscreens in the last six months. The ones I run across either have the lines on the screen or are completely blank. Most are mounted inches from the waterline and are exposed to all the heat, humidity, and chemicals they can handle, until they can't. IMO it's a mistake when the hot tub manufacturer mounts them in the tub instead of in a molded area on the top lip. Hopefully big B will beef up the waterproofing or, save the touchscreens for cell phones. spokanespas.com

Just FYI for future spa owners with this same problem, we do these relay replacements all the time. spokanespas.com

The disk looks like it's a broken off piece of a bromine floater. Absolutely remove it and yes, you'll also want to ditch the Eco Pur two stage filter and just use the same type single stage filter the other side uses. The Eco Pur filters clog quickly, starve the circuit pump, and are expensive. For these circ pump/low flow applications I recommend Pleatco brand filters as their open core design allows more water flow even as the filter media clogs over time. Good luck, spokanespas.com

Sounds like a sticking heater relay. OH may not occur during filtration cycle because water is still moving through heater but when water flow stops and heater relay is stuck on the high limit will trip. This is a repairable failure. spokanespas.com

Sounds like a stuck on flow or pressure switch. When the error occurs remove one wire from flow switch, error should clear. If it's a pressure switch it may be out of calibration, adjust out then back in to 2psi.

If you have "- - - -" on display and the spaside still responds to jet, light, temp button pushes there is a flow error. If you have "- - - -" on display and the spaside is unresponsive there is a high limit error. Low flow can cause either of these issues. Possible causes are dirty filter, weak or restricted circulation pump, bad flow sensor, or bad high limit. Remove your filter and see if the error goes away. If so, the filter needs to be cleaned or replaced. Cartridge filters should be cleaned monthly and replaced annually. Brandon@spokanespas.com

Sounds like a bad connection where the temperature sensor plugs in to the circuit board. Possible cold solder joint on the receptacle pins. Possible bad sensor. Brandon@spokanespas.com

Does the spa have an Ozonator? If so, disconnect from circuit board and see if the problem persists. Brandon@spokanespas.com

Likely a loose connection at the 3/8" nuts connecting the strap to the board, heater, or both. Can also be caused by a cold solder joint or fouled relay points. This is a repairable failure. Brandon@spokanespas.com

It sounds like there is a bad diode on the circuit board. The failure often coincides with a sticking heater relay which causes the temperature sensors resistance to lower and therefore current to rise in the sensor comparator circuit. This is a repairable failure. Brandon@spokanespas.com

There may be a cold solder joint on one of the pins where the temperature sensor plugs in on the circuit board. Brandon@spokanespas.com

Hello, The solid FLO error on the Jacuzzi and Sundance LCD panels occurs only when the spa is in "Summer Logic" mode and there is still continuity across the flow switch. This error code is not found in the owner's manuals. If the spa temperature is above 95 degrees Fahrenheit and the water temperature is 2 degrees Fahrenheit above the set temperature the circulation pump will shut off until the water cools to the set temperature. If continuity is detected during the summer logic mode you will get a solid FLO code. The reason this usually occurs is a stuck-on circulation pump relay on the board. This is a repairable failure. brandon@spokanespas.com
