I posted a reply on how to repair the pump to someone’s comment about trying to find a pump last night. I can’t see my reply now. What I found was the one end of the shaft had worn down to only about 25% left. I posted removing the shaft and cutting it, then flipping the shaft to put the worn end back inside the impeller/magnet housing. I did this on my original Chilipad and works fine. I just looked at my 2nd Chili Cube and found the shaft in the pump on that one is plastic or some other type material, maybe Ceramic ?? The original one has a stainless steel shaft. BTW, the shaft is 2mm x 56mm. If you’re in Canada, Sayal.c o m electronics sells a back of 100 of these stainless steal shafts but a bit longer, for under $4.00. At least 100 is what the web site says.

The pump suggested above (++http://a.co/392FAtj++ ) is 12V one, the Chilicube requires a 24V one.

One of these items on Amazon would be a better option: ASIN B08HWBX2RH or UPC 738680103352

I was searching for information on the cube to try see if I could add some wifi or bluetooth control through an Ardiuno or something.. Good work on the guide.!!!
