Bad Solenoid?

[JPMorgan]

We have a Controller that controls the flow of bromine and acid to our indoor pool. Has been working well to keep snaitizer and pH at appropriate levels. Recently I noticed that bromine level was rising, but Controller was still calling for more bromine. I was told that a solenoid has gone bad and needs to be replaced. Make sense? Could it be anything else? Thank you.

If the controller is calling for more bromine I would imagine it’s a sensor and not the solenoid. What’s the name of the controller?

Thanks for your reply. I will check the name of the controller and get back to you.

It is an Aquasol. The pool company asked me to unplug the Controller to see if the "pea" in the vertical site glass for bromine flow dropped to the bottom. It didn't and he diagnosed it as a bad solenoid (said the "pea" should drop to the bottom of that site glass when the Contoller is unplugged).
