2 1 SAFETY 1.1 Safety instructions Comply with the following instructions: Attention Danger! Repairs may be carried out by a qualified electrician only! The user may be put at risk and injured by improper repairs! To prevent electric shocks, always comply with the following instructions: If the appliance is faulty, the housing and frame may be live! Electric shock may occur if live components are touched inside the appliance! Before commencing repairs, disconnect the appliance from the power supply! If tests have to be performed while the appliance is live, always use a residual-current-operated circuit-breaker! The protective conductor resistance must never exceed the values specified in the standard! The protective conductor is crucial for personal safety and appliance function. When repairs are complete, perform a test in accordance with VDE 0701 or the corresponding national regulations! When repairs are complete, perform a function and leak test. Conduct the safety test in accordance with VDE 0701 via the connector as follows: The differential current must be measured on the appliance! See circuit diagrams test programme The following pictograms are used in the repair instructions: Electrostatic sensitive devices! Please observe handling regulations! Sharp edges: Wear protective gloves doc Seite 2 von 32

3 1.3 ESD Term General Electrostatic Sensitive Devices State of the art electronics achieve economic efficiency, environmental protection, user comfort, high functionality and operating safety in electrical domestic appliances. This high quality technology requires professional handling and competent specialist knowledge. All electronic modules are fitted with components which are at risk from electrostatic voltage. of up to 35,000 volts if you walk across a non-conductive carpet, of up to 12,000 volts if you walk across a non-conductive PVC floor, of up to 1,800 volts if you are sitting on an upholstered chair. The electrostatic voltage on your body is transferred to the electronic components and ESDs you touch which may be damaged as a result. Shot down! A dead component A dead assembly A dead appliance Components which are at risk The following components are at risk from electrostatic voltage: µ processors and ICs Transistors, thyristors and triacs Diodes Wounded! Damaged Debilitated Early failure Causes and effects You are carrying an electrostatic voltage: doc Seite 3 von 32

4 1.1.3 ESD instructions All electronic modules and electronic assemblies feature electrostatic sensitive devices. The following measures must be taken in order to protect these electrostatic sensitive devices: Ensure that the assemblies and modules are appropriately identified. Before you touch and measure the ESDs, put on an electrostatic protection system (wrist band with earthing module). Avoid touching ESDs with chargeable plastics (film, etc.). When taking hold of assemblies, modules and printed circuit boards, try not to touch the printed conductors or connections. Keep ESDs away from monitors and television sets. Only use conductive materials or the original packaging for transportation Electrostatic protection system The electrostatic voltage of the body is discharged via the wrist band and the earthing module. For reasons of safety this does not occur directly, but via a combination of resistors. The earthing or protective conductor connection must not be damaged! doc Seite 4 von 32

Plug-in contacts / components. Observe care symbol (see general repair instructions ). Remove foreign objects. Scorched plugs / replace components. Chemical odour Detergent / fabric softener / scented cloths. Change detergent / fabric softener / scented cloths; if possible do without fabric softener / scented cloths doc Seite 28 von 32

29 7.2 Unsatisfactory drying result Customer complaint Cause Remedial action Appliance starts only briefly. (Programme is ready after 2 5 min.) Inserted washing is too dry (<5%). Advise the customer. Short-circuit or shunt in conductivity system. Start test programme to measure conductivity. See circuit diagrams. Washing not uniformly dry. Drum and end shield electrode soiled, e.g. by fabric softener or scented cloths. Ambient temperature below 5 C. Wrong drying programme selected. Blended fabric (different fabric types). The residual moisture cannot be measured correctly due to wrong types of textiles used in wrong programme (e.g. cotton textile dried in easy care programmes). Filter soiled, e.g. by fabric softener or scented cloths. (Drop test) Clean drum and end shield electrode with vinegar water. Increase room temperature. Advise customer. Select programme with higher degree of drying. When programme ends, additional drying temporarily. Check kind of textiles and programme selection used by customer. Advise customer to use only cotton programmes to cotton textiles and easy care programmes to synthetics. Easy care does not mean delicate drying! This function is available with Delicate button.
