I know several others have experienced what I have with their Anova Sous Vide. While I was cooking, the screen went out, but the machine still works. I can hear the pump running and I can see the temp on the App, but no display on the unit. Alway, I have contacted Anova for some insight on how to repair or replace, and am getting shot down because I don't have a receipt. This was a gift from in-laws, and I know they do not have the receipt anymore. Has anyone come across these issues and can give me some insight on how to repair or replace the damaged unit?
