Tunze Nano ato failure

[lilphil26]

Well this has happened 3 times now. The first time it failed to shut off which i think was to due with the magnet holder and float switch. Now it has failed to come on twice in 5 days. Sunday and now again tonight. If i pull the barrel connector from the tunze controller and plug it back in, it will work. Any idea what is going on? Im going to make up a gravity fed ato just in case this thing dies again when im not home to babysit it.

Thanks,
Brad

How big is tank? Out of the box it is set for 25 gal or less and turns itself off as a safety if the pump runs for more than 1.8 minutes. On a larger tank you need to change the safety timer to 3 minutes, pages 21-29 explain the safety timer system.

The tank is an innovative marine 25 gallon fusion. The pump chamber is very small and normally the pump runs for approx 4 to 5 seconds to fill up until the float switch kicks it off. Must be something else

I think it has to be the pump, we can send a new one, email me your receipt- Tunze at sbcglobal dot net. If the pump draws too much power, the controller shuts it off.

Ok thanks, you are probably very correct. The pump has been louder than normal lately. Thanks so much!
