I have an Aqualink RS8 all button pool/spa system.
Last week the pool and spa lights came on when the system went into spa mode.
Neither the home controller or PCB showed that the pool light was on. Light went off when switched back into pool mode.
I could hear a series of "clicking" sounds when it switched over to pool mode.
Yesterday the pool light turned on and stayed on, regardless of mode (pool, spa, spa drain, spa fill)
I Reset the PCB panel, and the spa actuator turned to the opposite direction and now does not respond to the PCB. It does turn when using the actuator switch.
I replaced the actual pool light, pool light relay last year as well as the GFI. The pool light does go into the GFI.
The actuator did have a leak so maybe a short circuit to the PCB? The panel has full power and everything else works fine.
Thanks in advance.
