    There are several possibilities that could be causing your problem. However, the most common fault is the solenoid coils which open the valve to allow refrigerant into each hopper. Please see the ports manual at "http://www.partsguru.com/user/Bunn Manual ULTRA2 Illustrated parts 32081.0001.pdf". I think the part you will need is "32133.0001". Before you get carried away though there is one simple thing you can do to prove it is the solenoid coil. In a two-bowl machine there are two solenoids. These are identical. Swap them over and the fault should follow the valve. Here is a site with some useful information about how to do this.http://sites.google.com/site/sencotelsol...

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.

I have come across this problem before. If it keeps freezing in the off mode more than likely you have a faulty main PC Board.
Contact here at Just Refrigeration we do have spare main PC Boards for the Bunn Ultras

the word "gourmet" next to the display is a button. hold it down for a few seconds and you'll get into the menu. keep pressing and releasing "gourmet" until you get to "factory reset" and select yes. after that, you'll have to reset all the other settings like the clock and the defrost timer.

I have bunn slush ultra 2. 1 side freezes 1/2 way, like slushy a little bit but still watery, other side is only chill. both are set to 16 thickness.

make sure both say "ICE" on the display. press the snowflake buttons on the front to get it there. also, make sure you are mixing the product properly. if still an issue, you may have a small refrigeration leak that should be looked at by a professional

Bunn won't freeze the drink, the drum freezes and ices over but 3 hours later no slushy.

clean the filter and condenser coils, leave at least 6 inches of space for it to breathe

go into the menu (hold down the "gourmet" button) and select reset all. then check your mix to make sure it's the proper ratio. too lean will cause it to freeze too fast.

Our Bunn Ultra II is just not freezing despite being cleaned. We've checked many things to no avail. Help?

low refrigerant, high brix, no airflow are the most common problem. if it's clean and proper product mix, may have low refrig.

My ultra 2 is not freezing anymore and screen says torque error. how do i fix it?

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.

Right Hopper not Chilling

There could be one of 3 things:

1- The temp sensor on the back of the machine is not working.
2- The auger may be damaged.
3- The pins on the shaft could be covered with product.
