Has anyone else had a problem with the impeller on the Precision Cooker? Mine died after approx 8 hours on the first use. The unit powers up, but due to the dead impeller and thus no circulation, the temperature fluctuates rapidly over a 2-3 dgree celcius range, and beeps incessantly as it keeps reaching the target temperature before flying off again. ---

I would suggest contacting [support@anovaculinary.com](mailto:support@anovaculinary.com) There have been a couple of issues like this before. If it did not work at all I would suggest checking that it did not get pushed over to one side impeding its ability to spin. I have heard a couple of clicking issues that were traced to this. ---

Hi, Thanks for the reply. The unit was working perfectly for 8-9 hours, sitting at 60 degrees celcius without any deviation. I switched the unit off at the wall socket for five minutes to use another appliance, and when I powered the Anova back up, the impeller did not spin. I hadn’t touched anything between power down / up. I have contacted support - so far no joy. ---

I am sure they will get you back cooking in short order. ---

you could also check that the screw holding the impeller into the shaft has not come lose. That happened with mine, luckily it’s a simple fix. ---

I checked the screw - tight. I’m pretty sure it is related to the power off/on. I’ve uploaded a couple of videos to show the problem http://www.digitalimogen.co.uk/anova/anova1.mp4 and http://www.digitalimogen.co.uk/anova/anova2.mp4 The first is the impeller wth the housing off, showing the free-moving impeller. The second shows the unit in use, with the temperature hunting behaviour, and at the end shows the impeller which is stationary.  ---
