Question about Bunn Kitchen Appliances - Others
I have a bunn ultra II and one side freezes in normal time but the left side takes about 30% longer. And in harder conditions like with alcohol or warmer temperatures, it may not freeze at all. To be clear, it does freeze. All the problems and solutions oI can find are for when one side just quits working
It needs an ambient temp of 75-80 degrees to work well. to hot, it struggles and can't cool down. make sure you have at least 6 inches of space behind the machine so it can breathe, and clean the filter regularly. the mix has to have a brix level (water to sugar or "antifreeze" ratio) of about 12. to rich and it won't freeze. to lean and it'll ice up. alcohol brix is too high. you may also have a small refrigeration leak

Check the back of the machine where the big plastic cover is, you will have to remove the 2 screws back there, and the 2 hoppers as well as the metal platform. When you remove the cover you will notice a mountain of product covering the shaft and the little CPU board back there, clean replace shaft seal and bushing and make sure that the red and white lights on the board have no product on them.

You need to go through the menu and tell the machine that the maintenance is done, hold down the middle button to get to the menu, then follow on screen prompts and navigate to shaft seal maintenance.

make sure it's mixed properly. if there is toomuch water, it'll freeze solid. if the mix is too rich, ice will form on the outside of the bowls. you may also have a low refrigerant level.
