B) Figures below, from the distribution board, unplug a pump (your choice) then continue to part C to see if
this is the problem.
C) Turn the machine on (fan running). Does System Initialization reaches 100%?
Yes System Initialization reaches 100%! The unplugged pump may be causing the problem! To
confirm this turn the machine off, plug the pump back in, and turn the machine on. If System
Initialization does NOT reach 100% the pump is bad.
No System Initialization does NOT reach 100%! Turn the machine off and repeat parts B and C until
System Initialization DOES reach 100%. If after ALL pumps have all been unplugged and System
Initialization still does NOT reach 100% either the Actuator Cable OR the distribution board may
