The washing machine electronic program controller circuit is composed of the power supply circuit, multivibrator, flip-flop and control implementation circuit, and it is shown in Figure 3-205. Power supply circuit is composed of the power switch S, buck capacitor C2, resistor R8, rectifier diodes VD4, VD5, voltage regulator diode VS and filter capacitor C3. Multivibrator integrated circuit is composed of the time-base ICl, resistors Rl-R3, capacitor Cl and the normally closed contacts Kl-l, K2-1 of relays Kl, K2. Trigger consists of the voice control circuit IC2, diode VDl, resistors R4, R5 and capacitor C4.
