Miele Professional PT 7186 Vario Wäschetrockner Bedienungsanleitung

Ursache: Inadequate ventilation in installation room or blocked air intake at rear of appliance

Ensure sufficient ventilation through non-closable openings in external wall (min. 150 cm²) or open a window. Maintain adequate distance from wall and ensure gap between appliance base and floor is not reduced by baseboards, high-pile carpet, etc.

Ursache: Long exhaust ducts with many or tight bends causing excessive air resistance

Use flexible hoses or plastic water drain tubes with minimum diameter 100mm. Avoid long ducts and multiple tight bends. Calculate total duct length using provided tables to determine appropriate diameter (100mm, 125mm, or 150mm).

Ursache: Inadequate air supply to the room where dryer is installed

Provide adequate ventilation for the air needed during drying. Open a window, install non-closable ventilation opening in external wall (min. 150 cm²), or install window switch so dryer only operates when window is open.

Ursache: Exhaust duct outlet positioned incorrectly or too close to building structure

Position exhaust duct outlet (e.g., pipe through external wall) so moist air cannot be drawn back into the room and causes no structural damage or nuisance.

Ursache: Improper electrical connection or modification to power system

Have all electrical connection work, installation changes, grounding verification, and fuse checking performed only by authorized professionals complying with regulations (e.g., NEN1010). Use appropriate plug connection or fixed installation with all-pole disconnection switch (3mm contact opening in de-energized state).
