Stoelting Slush Machine Troubleshooting Solutions

Won’t Start

  • Unit is unplugged – See if the power cord is unplugged.
  • Toggle switch is OFF – If the toggle switch is in the OFF position, turn it to ON.
  • Toggle switch is broken or has loose wires – Have an authorized technician to repair the loose wires or replace the switch.
  • Blown fuse or tripped circuit – See if there is a blown fuse or tripped circuit in the building.
  • Reset switch is down – When the switch is down, it’s in the cut-out position. Flip the switch up, so it’s in the normal operating position.

Shuts Down When Running

Caused by tripped driver motor overload due to:

  • Incorrect Brix reading – Product should have a Brix reading between 11 and 13. Refill the machine with the correct reading.
  • Low voltage – Make sure the machine is receiving proper voltage. You might need to contact your local electric company for assistance.

Won’t Dispense Correctly

  • No mix or low mix in the product cylinder – The product cylinder and hopper need to be full for proper operation.
  • Lower half of the cylinder is frozen to the agitator – When this occurs, the mix is too lean. Thaw the mix and refill the cylinder with the correct mix.
  • Upper half of the cylinder is frozen – This also can occur when the mix is too leans. Thaw the mix and refill the cylinder with the correct mix.
  • No scraper blade – Make sure the scraper blade is on the agitator.
  • Overdrawn freezer – Slow down the machines rate of draw.
  • Trapped air under in the divider plate – Remove the excess air.

Product is Too Thin

  • Toggle switch is on OFF or CLEAN – If the switch is in the OFF or CLEAN positions, change it to SERVE.
  • Ambient temperature is high – If the machine is in an area that is around 100 degrees Fahrenheit, move the unit or direct hot air away from it.
  • Dirty condenser – Make sure to clean the condenser
  • Overdrawn freezer – Slow down the machines rate of draw.
  • Temperature adjusting tension spring is too loose – Adjust the tension spring to its correct setting.
  • Fan is stuck or motor is broken – These components should be checked or repaired by an authorized technician.
  • Refrigerant is low or leaking – Have an authorized technician check for a leak, repair and/or add refrigerant.
  • Expansion valve is broken – Contact an authorized technician to repair the valve.

Agitator Won’t Rotate

  • Agitator is stuck or frozen – If the product is frozen in the machine, thaw it so the agitator can move.
  • Drive motor overload tripped off – Turn the freezer off for five minutes before resetting it.
  • Drive motor has no power – Have an authorized technician check the wire harness and switches located in the drive circuit. The technician will need to repair or replace these components.
  • Drive motor is broken – Contact an authorized technician to check and repair the drive motor.
  • Drive cap pin isn’t engaged or is missing – Attach the drive cap pin by aligning the half-holes in the drive shaft and agitator tube.

Spigot Sticks or Leaks

  • O-rings are worn or missing – Drain the mix below the spigot level. Remove the spigot and clean. Replace the O-rings by lubricate and installing them.
  • Dried mix is in the spigot assembly – Drain the mix below the spigot level, and remove the spigot retainer and spigot. Disassemble and clean it with hot water and brush. Once it’s dry, lubricate, reassemble and install the assembly. Then, refill with the liquid mix.

No Ice Crystals During Initial Freeze Down

  • Mix is too rich – If the mix is too thick, check the Brix reading. Make sure to fill the machine with a mix at the proper Brix reading.
  • Low consistency setting – If the product is too thin, the consistency setting is too low. Change it to a thicker product setting.
  • Blown fuse or no input power – See if there is a blown fuse in the building or no input power.
  • Air flow is restricted to the unit – Air enters and discharges from the front and back or sides of the machine, depending on the model. Clear these areas, so air can flow properly to the machine.
  • Dirty condenser and condenser filter – Make sure to clean the condenser and condenser filter
  • Reset switch is down – When the switch is down, it’s in the cut-out position. Flip the switch up, so it’s in the normal operating position.
  • Toggle switch is OFF or on STIR – If the toggle switch is in the OFF or STIR position, turn it to ON.
