Information:
When the door moves from the closed setting [I] (Door latch 8 is vertical) to the
airing setting [II] (Door latch 8 is horizontal), the door magnet 11 (in the inner worm
10) removes itself from the door contact switch 12 in the door catch 9. Via the
electronic 1 , a contactor through the phase angle rotation breaks the motor (only
when the motor has been switched on a minimum of 5 seconds before) and the
electric supply to the following processes is interrupted:

Motor 2 with fan (Contactors K5, K50, K55, K56, K57)

Convection heating 3 (Contactors K4, K41, K42, K6, K61, K 62) in Electric units

Immersion heating element Steam generator 4 (Contactors K1, K2, K3) in
Electric units

Convection burner 3 (Automatic firing N20, N22) in Gas units

Steam generator burner 5 (Automatic firing N21) in Gas units

Solenoid valve Y4 (Water supply to injection 6) in OES and OGS
