Osmolator Universal 3155 Stopped Working

[Luke Schnabel]

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....

Hit up Roger at Tunze, he'll have it sorted for you quickly:

Either the wrong power supply is accidentally connected, or the pump is dead. Verify you did not accidentally connect the power supply from another device and then try it with the pump disconnected. It is cycling off an on either from an overload at the pump connection which could also be due to these connectors being shorted by saltwater or getting power outside the range of 10-15V at at least 1200mA.

Tunze has grate customer support. I had an ATO that went bad last year. Shipped to Tunze in Texas I think. They fixed it and had it back within a week. No charge besides shipping there.

Thanks for the reply @rvitko The alarm was sounding and nothing was touched. I went ahead and unplugged the pump and then plugged the power back in and the same thing is happening. Does that mean the pump has failed?

 

[Luke Schnabel]

I don't have anything to measure the voltage though I may ask a friend if he can come check it out.

 

[rvitko]

Check that the power supply indeed says Tunze 5012.010, for example the power supply from an Apex or any powerhead would also cause this. If it did this with the pump disconnected, the issue is elsewhere and most likely it is with the power supply.

Ok It is indeed the Tunze power supply plugged in. I don't have the tools to test the voltage but I don't know how all off a sudden after about 14 months it would just change? from the best of my knowledge there hasn't been any water anywhere around it.
Could I send it in to you guys and see if the controller needs replaced?

When the pumps go bad (which is very common) this is NOT what they do. Usually a bad pump will just stop running or make noise with no water movement. Sounds like you have a problem with the controller unit itself.

 

[Tom Blevins]

been though this over the years just by a new one.

 

[Luke Schnabel]

I'm not going to buy something new to replace something that stops working in 14 months. If I did that I would just buy the cheap stuff.

He said it's not the pump since I've disconnected it and the problem still happens.

Yes, bad pumps can cause the controller to flash all 4 lights and beep, it depends on the age of the controller, since 2012 a lot more onboard diagnostics and safeties were added. In this case I don't believe it is the pump, but I have never seen it be the controller, a controller problem will usually be a flashing too low light only shortly after start up (memory erased) or a flashing too low light and solid too high light with or without the green level light (water damage). It has a 2 year warranty, water damage is not covered but we make our best effort to repair it and provided only cleaning and touch up is needed we don't charge for such a repair. Please send it in, include a note with return address and phone number, the pump (bagged separately) power supply and controller.
