My wife and I have an “Onga RP3000SC” as our saltwater cholorinator.
It is currently set to run 8am – 10am and 2pm – 6pm.
Yesterday I noticed that it was 9am and I could not here anything running. I went out and had a look at the chlorinator and the timer dial was correctly showing 9am but no power was supplied to the chlorinator/pump. I gave the timer face a gentle tap with my finger and everything powered up (and I flicked the switch to manual until such time as the 2 hours had been “caught up”).
I have the owners manual but it doesn’t have a great deal of troubleshooting information in it.
The above issue is intermittent, most days it starts up at 8am/2pm just fine and shuts down when it should.
Perhaps there is a simple way to remove the timer face and give everything a good clean (if that’s what the problem is)?
