43 Capacitor delta error. The maximum voltage difference between the main capaci-
tors has been exceeded. May be accompanied by errors
32-35. Check the output diodes.
Other
Error codes that contain three or four digits are defined as
fatal errors. These codes generally indicate internal errors
on the Control Board. If cycling the input power on the
machine does not clear the error, try reloading the operating
system. If this fails, replace the Control Board.
