Hi there, I have recently received an Anova Precision Nano as a gift from a friend from US. I managed to use it twice and worked like a charm. The third time, however the unit would not heat the water. It is only circulating it. Since this is a Nano, i doubt it can be opened and have the fuse changed(if that is the issue). Any advices? I have already contacted support and waiting for their response. Maybe there’s a way to hard reset? Thank you for your help. ---

I would wait to hear from Anova support. Were you using a voltage converter? ---

No, i did have a plug converter from us to eu socket. But i believe we have the same voltage. I have used US socket products before without any power issues. And the unit powers on, shows temperature, circulates water, just the heater element won’t work, for some reason. ---

With other devices I have heard of issues with converters. The voltage spikes have been known to damage more sensitive electronics. I am not saying that is definitely what happened just a possibility. ---

North America is 110/120V EU is 220V/230V. A lot of converters are problematic for high amperage devices (such as coffee makers, hair dryers and your Anova Precision Cooker). Your friend should have gotten you an EU unit - you’re likely only to have issues (and most appliance manufacturers won’t warrant their devices with 3rd party converters). ---

> [@fischersd](#): > > North America is 110/120V EU is 220V/230V. Also, the 110v/120v in North America is at 60 hertz frequency. The 220v/230v in Europe is at 50 hertz frequency. I’ve heard the frequency difference can make things problematic with some sensitive electronics. ---

So, Anova Support replied, they will not support a replacement since what i did violated their warranty. Now, the question remains if using the 110/120V in a 220V socket has definitely fried something, or not, and if it did, what would be the first part to die - fuse?. the thing is that i was able to use it 2 times without any problem. I would assume it would be the fuse to protect the other electrical components and avoiding fire or anything worse. So since the warranty is gone, how can i tear the nano apart? there is no screw visible anywhere to remove that plastic sleeve that’s over the heating coil. if i get that off without breaking anything i can then open up and check if the fuse is toast. Any nerdy engineering advice? Calling all DYIers 🙂 Thanks, Andrei
