PROBLEMS

POSSIBLE REASONS & SOLUTIONS

Motor Doesn’t Start or Blades 
Don’t Rotate.

Check that the bottom of motor head is clean and there is no food blocking 
connection when placing on containers.

There is too much food in the container.

The unit has overheated. Unplug and wait approximately 10 minutes before 
using again.

Make sure the splash guard is securely on container. 

Make sure the power head is securely placed on splash guard.

Check that the plug is securely inserted into the electrical outlet.

Check fuse or breaker. Replace fuse/reset breaker.

Food is Unevenly Chopped.

Either you are chopping too much food at one time, or the pieces are not 
small enough. Try cutting the food into smaller pieces of even size and 
processing smaller amounts per batch. 

Food is Chopped Too Fine or is Too 
Watery.

The food has been over processed. Use brief pulses or process for shorter 
time. Let blades stop completely between pulses. 

Food Collects On Splash Guard/
Safety Cover or On the Sides of the 
Master Prep

 Pitcher or Master 

Prep

 Bowl.

You may be processing too much food. Turn the machine off. When the 
blades stop rotating, remove the power head and the splash guard. Remove 
some of the food being processed. 

You Cannot Achieve Snow From 
Solid Ice.

Do not use ice that has been sitting out or has started to melt. Be sure to use 
short pulses in the beginning to break up large pieces.
