1. PURPOSE OF THIS SERVICE
MANUAL
The purpose of this Service
Manual is to provide Service Engineers, who
already have the basic knowledge necessary
to repair household washing machines, with
information of a general nature regarding
the HEC range of washing machines.
More detailed information
regarding specific models may be found in
the Service Notes and Service
Manuals (issued separately)
for each specific model or functionality.
This information covers:
2. 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.
3. CAUTION:
- Before servicing
receivers covered by this service manual and
its supplements and addenda, read and follow
the SAFETY PRECAUTIONS of this publication.
Remember: Safety First.
- General Guidance
An isolation Transformer should always be
used during the servicing of a receiver
whose chassis is not isolated from the AC
power line.
- Use a transformer of adequate power
rating as this protects the technician from
accidents resulting in personal injury from
electrical shocks. It will also protect the
receiver and it's components from being
damaged by accidental shorts of the
circuitry that may be inadvertently
introduced during the service operation.
