Follow the step-by-step guide to properly diagnose the error. Pay special attention to those tests
indicated in numbered boxes, and described in detail here below:
CAUTION: carry out these checks with the machine powered and the start switch set to
ON.
(1) Insert the multimeter probes between pins of the CN11 connector on the power entry (between
the blue and black cables). You should get a reading of approximately 220 Vac or 110 Vac
depending on the line voltage.
(2) Insert the multimeter probes between pins of the CN13 input connector on the start switch
(between the blue and black cables). You should get a reading of approximately 220 Vac or
110 Vac depending on the line voltage.
(3) Insert the multimeter probes between pins of the CN14 output connector on the start switch
(between the blue and black cables). You should get a reading of approximately 220 Vac or
110 Vac depending on the line voltage.
(4) Insert the multimeter probes between pins of the CN15 input connector on the fuse holders
(between the blue and black cables). You should get a reading of approximately 220 Vac or
110 Vac depending on the line voltage.
(5) Insert the multimeter probes between pins of the CN16 output connector on the fuse holders
(between the blue and black cables). You should get a reading of approximately 220 Vac or
110 Vac depending on the line voltage.
(6) Insert the multimeter probes between pins of the CN17 input connector on the filter (between
the blue and black cables). You should get a reading of approximately 220 Vac or 110 Vac
depending on the line voltage.
(7) Insert the multimeter probes between pins of the CN18 output connector on the filter (between
the blue and black cables). You should get a reading of approximately 220 Vac or 110 Vac
depending on the line voltage.
