My Baja spa is not heating up. It says FLC on the display. Do you know what the problem would be? Any help much appreciated

Hello,

My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.

Is the main pump running?

Customer: replied 6 months ago.
pump is running fine

Thank you,

The code is saying that a flow switch is not making contact. Usually the water movement from pump closes a switch in the flow and then heater can run.

Have you tried running with filter out as a test?

Customer: replied 6 months ago.
No, but not sure I know hat to expect without the filter. What will that tell me?

even when you clean a used filter it is restrictive. It may look clean but still impedes flow more than a new filter.

I always remove filter and see if it works just to eliminate a dense filter.

It is either a filter or you have a bad flow switch.

Do you know what/where the flow switch is?

Customer: replied 6 months ago.
No I don't know what or where the flow switch is! Can u guide me? Thx

I do not know what model you have in the Baja series..so you would need to remove service door and take pics so I could guide you. You can attach here using the attach files link

Customer: replied 6 months ago.
I tried the filter removal and it still says FLC Will remove door now and see if I can take pics. Thx

standing by

He is document on the flow switch code

Customer: replied 6 months ago.
Bigger operation than I expected I will have to remove cover rail to get door out...

Just respond as you can. Many of my questions go on for a couple days.

Customer: replied 6 months ago.
I think I added a photo

I only see a shoe :)

Customer: replied 6 months ago.
BtW as I turn it on I can see the yellow light go on and then half of it clicks off immediately

did you get the troubleshooting form I sent for FLO/FLC?

Customer: replied 6 months ago.

Customer: replied 6 months ago.

Hi Billy,
Will it be attached to te tub itself? Or to the electronics?

it will be attached to a main water pipe

Customer: replied 6 months ago.
Could it be on any side of te tub? I am not seeing it yet? I see it will be attached to teh main water pipe, but then not also to teh tub itself? Also I assume it will have wires going to it, right?

did you remove the cover of the control center yet?

Customer: replied 6 months ago.
No, not the control center itself
Customer: replied 6 months ago.
Do you mean the box in the picture that says "Command Center"? But taht just has elctronics in it, no water pipes

ok...we need to remove that cover

Some are hidden inside the control center

see here

Customer: replied 6 months ago.
Now I see it. What to do with it?

first..refer back to the chart about adjusting by turning the slot...yours is on the bottom...count rotations you turn and go all the way both directs and then back to original..restart tub and tell me code

Customer: replied 6 months ago.
Looks like I need an ohmmeter. I'll have to get one tomorrow. Be back to you then. Thx!

just respond when you can

Customer: replied 6 months ago.
Had to take yesterday off tub repair as it was raining. Trying the switch code test now. I'm having trouble getting the wires off as they seem to be clipped on. Is that step necessary? Not sure I see why it should be

basically it wants to open the circuit and removing wire does that

Customer: replied 6 months ago.
Ok got it off and turned the flow switch way to left and then back. Never could get the ohmmeter to register anything with wires off no matter where the flow switch was turned. Anyway, I put the wires back on and it seems to be working...

Yep...when you turned up and back down it released it from being stuck..

Go ahead and use tub but I would get a spare on the way just in case.

Billy

Customer: replied 6 months ago.
You mean a spare flow switch?

correct. Sometimes they stick and will never stick again.

Other times they seize up again the next day....
