9.8 Replacing the control circuit board
1) turn off the master switch and disconnect all the wiring to the machine.
2) turn the machine on its back and remove the four screws (U1) securing the bottom plate (U), which
can then be taken off (fig. 39).
3) disconnect all the connectors on the board (from 1 to 13, page 44).
4) with the special tool (U2) provided with the replacement board (fig. 41), release the five clips on the
board.
5) fit the new board, engaging with the special catches, and connect all the connectors, taking care not
to exchange the two connectors “10” and “11”. The other connectors are polarized and therefore
cannot be interchanged or fitted wrongly.
WARNING: after replacing the board, check that all parts of the machine are working properly, using the TEST
function (ch.8, page 33).
