My mastertemp 400 has the service heater light is on, but there are no error codes in the panel nor on the back of the board. I disconnected the flow switch and no lights came on. Any idea what the issue might be? Attached are 2 photos showing the service led but no error code leds

Is Service Heater still on?
Turn off power and then restore power and show the bootup process and check for errors if the Service Heater Light comes back on.
The following are the LEDs:

I took the covers off and checked the igniter. Seemed OK. At first, I turned it on and just the fan came on - it didn't do that before. Turned it off and and again, and now it's heating - for the moment. It might not work, if I turn it on and off, but I wanted the spa to get to temp and see what happens, and to let my wife use it to help with some physical therapy that she's doing.
Well the spa heated to 80 then shut off with the service error. I'll have to look at it later.
