  • Page 6: Purpose Of This Manual

    1 PURPOSE OF THIS MANUAL The purpose of this manual is to provide service engineers who are already familiar with the repair procedures for traditional washing machines with information regarding washing machines fitted with the EWM10931 electronic control system (SERIES 7/8/9). Previous platforms (electronic/mechanical) used a safety pressure switch which controlled the minimum water level in the tub, beneath which the supply to the heating element was interrupted.

  • Page 7: Warnings

    2 WARNINGS Any work on electrical appliances must only be carried out by qualified technicians. This platform is not fitted with an ON/OFF switch. Before you access internal components, take the plug out of the socket to cut the power supply. If the heating element needs replacing, replace it with one featuring the same characteristics (2 thermal fuses) so as not to compromise the safety of the appliance.
