Balcf Posted August 25, 2021 Report Share Posted August 25, 2021 Has anyone managed to fix a board related to this error “FLO” for a Gecko IN.XE-5-11-H4.0? I ask before I start from scratch to fix my spa. I cannot afford a new controller 700CAD. Quote Link to comment Share on other sites More sharing options...
cranbiz Posted August 25, 2021 Report Share Posted August 25, 2021 Are you sure it's the board? The first thing to do is pull the filters and see if that resolves the issue. If not, then start by testing the flow switch with a multimeter. Make sure the flow switch is functioning correctly. The flow switch should complete a circuit when water is flowing past it. Unplug the sensor, put a multimeter across the 2 wires set to test for continuity, the meter should read an open with no flow and shorted when water is flowing. 1 Quote Link to comment Share on other sites More sharing options...
Balcf Posted August 25, 2021 Author Report Share Posted August 25, 2021 Yes, I did it. I have tested without filters, I replaced the heating element with flow sensor and nothing. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted August 26, 2021 Report Share Posted August 26, 2021 That leaves board or pump/flow issue. I assume that is on the main 2 speed pump? Probably not a flow issue, or you'd be talking about your jets not working. Looks like a board to me. @CanadianSpaTech, Gecko Guru Extraordinaire, any thoughts?

Balcf Posted August 26, 2021 Author Report Share Posted August 26, 2021 I checked the pump flow and all good. That means is the board. Tomorrow somebody will send me another similar board with the same issue and I will start the dissection. Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted August 26, 2021 Report Share Posted August 26, 2021 https://www.geckodepot.com/fichiers/documentsProduits/GDA/en/Techbook_in_xe_EN.pdf pages 43, 44 are you sure the sensor connections off the heater tube connecting to the board is good. The sensor connector is tiny and can be hard to attach. Or remove it and check for bent pins off the circuit board. Verify water level is high enough, filters out until issue is fixed, check for partially closed gate valves, When you power the spa up does the main 2 speed pump start in low speed and you have water flowing in the spa with normal pressure. The sensor needs a good flow rate of water from the pump or it will throw an error. Check the face of the pump for blockage. I've pulled everything from kids toys to t-shirts and G strings out of the front of the pump. Are the pump returns in the foot well clean/clear of debris? 1 Quote Link to comment Share on other sites More sharing options...
Balcf Posted August 26, 2021 Author Report Share Posted August 26, 2021 Yes, I did everything. For the sensor I have changed the entire system ( heating element with sensor installed brand new) and the same problem. My friend have has the same problem and finally he changed the entire controller. I think this is a common problem for this model. He will bring his defective controller and me I will try to fix it. I have checked the pump, the valves and everything is ok. 1 Quote Link to comment Share on other sites More sharing options...
Falcon72 Posted August 28, 2021 Report Share Posted August 28, 2021 Following - I have the exact same issue with the same controller. I just replaced the heater with the pressure switch and the error is still there. The filters are out of it. I guess this means control board is bad. Balcf - please post what you learn on the defective controller. Quote Link to comment Share on other sites More sharing options...
Gbo Posted September 15, 2021 Report Share Posted September 15, 2021 I have the same spa pack gecko In.xe-5-11-h4.0 had a oh error and a nr error figured out that pump 2 is running on high all of the time. Heated up to 112 i unplugged pump 2 and tub works perfectly. Going to change the relay if I can. Does anyone know… is that changeable or soldered in? Does anyone know what relay I would need to purchase? Quote Link to comment Share on other sites More sharing options...
cranbiz Posted September 16, 2021 Report Share Posted September 16, 2021 Soldered in. If you can solder, you can change it yourself. Just search of the relay numbers on the old one to find a supplier for a replacement relay. If you can't solder, an electronics guy can certainly do it for you.

Paul Moon Posted November 13, 2022 Report Share Posted November 13, 2022 Hi, did this get resolved. Did soldering the relay fix it. I have exactly the same problem, start-up pump kicks in for 1 minute or so and is meant to stop when the second pump kicks in but doesn’t. Start up pump keeps on running unless unplugged. I have changed the gates as one was sticking but still get the flow error on display panel. Everything else works as normal, but I want to have all seats with jets.
