5. Fault Codes and Test Procedure:

Customer Service
If, before the spin, the control detects a potentially out of balanced load, during its pre spin cycle at
93 rpm, it will slow down to 45 rpm and rotate both clockwise and anti-clockwise, in an effort to
redistribute the load. It will try again at 93 rpm. If the load is now balanced the program will
continue to spin as normal. The program will attempt to distribute the load 10 times before
displaying “Unb” at the end of the cycle if it was not possible to balance the load.
