[2005 Hot Springs Vista rapid relay clicks, display turns on and off, endless cycle.]

I tried powering off the spa, but that didn't help. I removed the filters, also no change. Lim OK LED flashes rapidly accompanied by clicking relay, then Control Disconnected LED flashes, then stops. This repeats endlessly. I measured the voltage on the white wire leading from the Relay Board to the Control Board. It has 127 v. I disconnected the  ozonator, circulation pump, and both main pumps from the board, but the same behavior (clicking and flashing) occurs. I measured the resistance of the recirculation pump and it was 40.8 ohms. The clicking appears to be coming from one of the relays behind the metal bar, but I am a bit nervous about trying to touch them because they are close to real power. I also checked the recirculation pump fuse and it is good. I could not detect any power going to the recirculation pump. I suspect that the main board is bad. I have attached a picture of the control board below. I don't see any obvious signs of damage. Is there anything else that I could try? Thanks in Advance!

There are 2 cables for the light 

Turn spa off at the mains discount both cables for the light ones white the others red , turn tub back on and see what happens

It should be accessible from the equipment area.

Remove door and behind iq box in a round black cover just pulls away from surround inside, inside black cover is the same as the link you posted 

Its very unusual for a led light to go wrong its more likely the seal on the light surround has gone making the light lense weep over time it will corrod the light , when it stops working its usually to late damage done 

When tubs empty climb in and you can see the red rubber seal and your see if theres a break in it , obviously replace seal before fitting new light

Its the thermistors thats the problem which screw into the top of the heater , change them and your problems are history

A flashing red light means its a circulation issue ,a flashing green light means its a  Communication fault 

Hope that helps

I got a used hot tub and the previous owner had the pressure switch bypassed . When I take the clip out of the by pass it shows ready blinking and power. When I have the clip in the by pass in , it says power but no ready , idk if it’s bypassed correctly or not . 

When you remove bypass it shuts the heater off as it thinks theres no flow 

Hotspring do 2 no fault 1,5 kw heaters 1 with built in pressure and 1 with no pressure switch 

If your tub came with a heater with pressure switch you can use the non pressure switch heater but have to use the bypass which plugs in where the lead from the side of the heater (pressure switch cable) plugs in 

Pulling the bypass off makes the tub think theres no flow indicating theres a fault 

If either light flashes or both at the same time its telling you theres a fault and the spas shut down you only want to see soild lights red = mains power green means spas up to the temp you have set it to
