8.15 Drying heater (washer-dryers) 8.15.1 General characteristics The armoured drying heater is inserted into a watertight stainless steel tubular casing, and consists of two branches: ѓ when drying cotton fabrics, both heating elements are switched on (full power). ѓ when drying synthetic fabrics, only one element is switched on (half-power) to ensure delicate drying. Typical electrical power ratings (depending on the model): ѓ 1000+1000W ѓ 700+700W ѓ 700+400W ѓ 550+550W 8.15.2 Electrical symbol 8.15.3 Checking for efficiency DOES NOT HEAT: - check that the heating element is not broken: measure the resistance across the two terminals. INTERVENTION OF ELECTRICAL SAFETY CUT-OUTS:
- use an ohmmeter to check that the heating element is not connected to mass and check for current leakage (40 M Ω ). SOI/DT 2002-05 eb 86 599 35 23-17
