I replaced a cheap top off system and bought a brand new Tunze Osmolator little over a year ago. It has been working great till this week. It is flashing all four lights and sounding the alarm. I unplugged it and soaked everything in a vinegar bath for two days. Cleaned it up and rinsed it off and I'm still having this problem. When I power it on I get a green water level led. Then all LEDs off for about 5 seconds and then all flashing LEDs with the alarm.
I have not moved it or messed with it since day one nor have I added anything around it. I don't know what else I can try....
