IMPORTANT NOTES
Repairs to electrical appliances must be effected only by qualified personnel.
Before accessing the components inside the appliance, always remove the plug from the power socket.
Where possible, ohmic measurements should be effected rather than direct measurement of voltage
and current.
Certain metal components inside the appliance may have sharp edges. Care should be taken to avoid
cuts or abrasions.
Before laying the appliance on the floor, always drain any water by means of the system placed beside
the drain filter.
Never lay the appliance on its right side (i.e. electronic control unit side); this would cause the water in
the detergent dispenser to fall onto electrical components, thus damaging them.
After repairing the appliance, always perform the final tests.
