NB*** Spin Test will NOT test Hall Sensor in this mode. NOTE: ALWAYS
remember to offset counter weight when spin testing an empty machine
FACT: It is NORMAL for this unit to be unbalanced until 350-400 RPM –
counter weights will only align correctly after this RPM is reached
• Activate the SERVICE MODE first (ref: above).
• Press the SPIN key to start DIAGNOSTIC CODE check mode. .
• To cycle through the diagnostic codes (d1, d2, d3, etc.), turn the rotary cycle selector
(knob) either clockwise or counter clockwise.
• When turning the rotary selector key (knob) in one direction, it shows diagnostic codes
from the latest (d1).
• Now when turning the knob in the opposite direction it shows the diagnostic codes in the
reverse order. E.g. When it stops at “d5” and then turn backwards, it shows from “d4” to
“d”. (Refer to Diag. Code interpretation).
