8.21 Drying timer (washer-dryers) 8.21.1 General characteristics The timer is a timing device that powers the components needed for the drying cycle; it is used in models with electromechanical and hybrid timers. Actuation is by the contacts, which are actioned by a series of cammes. The cammes are actioned mechanically by a synchronous motor. The timer consists of two parts: 1. cotton/linen drying : both drying heaters are switched on alternately (full power) 2. drying synthetic fabrics : only one of the drying heaters is switched on (half power). The drying phase, which depends on the timer code, generally lasts up to 120 minutes; the last 10-12 minutes are dedicated to the cooling phase.
Important : Do not attempt to turn the timer counter-clockwise! 8.21.2 Circuit diagram 8.21.3 Contact closure diagram 8.21.4 Checking for efficiency 1. Check the timer motor windings for continuity. 2. Check that the contacts close as shown in the specific diagram relative to the timer. SOI/DT 2002-05 eb 92 599 35 23-17
