Repair instructions
In the event of a function error, check the following:
• Check that the fuse on the back side of the machine beside the power
connections strip is whole.
• Check that the voltage supplies to the electronic circuit card are OK. Measure
the voltage supply on board connector X83 between the following inputs:
- X83:1 - 3 approx. 7 V~
- X83:4 - 5 approx. 15 V~
- X83:6 - 7 approx. 13 V~
• Check the three glass pipe fuses on the circuit board (see illustration on the
preceding page). Fuse rating 1 A/250 V.
If the above points are checked and the function error remains, replace the entire
circuit board.
Removing the circuit board
1 Remove the left (seen from behind) upper protective cover from the circuit board.
2 Unscrew both of the rear brackets in the detergent dispenserand on the side
panel.
3 Remove the right upper protective cover.
4 Undo the board connectors from the circuit board. Be especially careful with the
flat cable to the panel’s push buttons. Note how the connectors are mounted.
5 Undo the three quick release brackets and remove the board, pulling first straight
back so that the display window on the back side of the board cleans; then to the
side.
