In case of burning on the main circuit board, check that the problem is not caused by another electrical component (short-circuits, poor insulation, water leakage).

Refer to the figures below in order to identify the component that might have caused the burning according to the position of the burned area.

The circuit board shown below is the version with the greatest number of components: other boards may not feature all these components (relay K4 and buzzer).

Notes concerning certain alarm codes

Configuration alarms E93-E96: If these alarms are generated (when the appliance is switched on), operation of the appliance is blocked and all the LEDs light. The diagnostics procedure cannot be accessed; the only option is to switch the appliance OFF (by turning the selector to position “0”).
Configuration alarm E94: For this alarm code, only the family for alarm “9” is displayed; the diagnostics procedure cannot be accessed, and the “rapid alarm display” function cannot be used.
Alarms EB1-EB2-EB3: In the event of problems with the mains power supply, the appliance remains in alarm mode until the mains frequency or voltage are restored to the correct value or the appliance is switched off (by turning the programme selector to “0”). The family of alarm “B” is displayed; the diagnostics procedure cannot be accessed, and the “rapid alarm display” function cannot be used. The complete alarm code can be read only when the abnormal situation has ceased.
Alarms E51- E52: During the diagnostics test, all the alarms are displayed. Normally, when the programme selector is turned from one test phase to another, the appliance exits the alarm condition and performs the phase selected. This does not take place in the case of alarms E51 (power triac on motor short-circuited) and E52 (no signal from the tachymetric generator on the motor): in these cases, the only option to exit the alarm condition is to switch the appliance OFF by turning the selector to position “0” (reset).

	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.

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.
