You should be competent with electrics with a degree of experience to do the above test has it involves opening your appliance and removing and replacing wires inside the machine that will become live once the wires are replaced and the washing machine is turned on, there is no "zero" place for mistakes on this job, if you do not fully understand house hold electrics you should not attempt the test.

(Note that if the washing machine has digital controls, rather than a mechanical switch, it almost certainly uses an electronic variable pressure sensor to detect the water level. These three-wire sensors are easy to interface, but we'll leave them for another time).
During ‘on’ time of spin direction timer IC2, the output of negative- edge triggerd JK flip-flop at pin 2 goes low to energise relay RL2 and washing machine motor rotates in one direction. During the off time of IC2, the output of N1 goes high again to de-energise relay RL1, which cuts off the mains supply to RL2 and the monitor stop rotating. Floating point trouble may occur at trigger pin 2 of IC1. Resister R8 over comes this problem by holding pin 2 high.
Excessive force can result in centrifugal stresses that could cause the appliance to move or walk across the floor. Most automatic washers are equipped with an off-balance or out-of-balance switch that stops the washer from spinning and causes a buzzing sound at any point in the cycle when an off-balance condition occurs. On some of the appliances, the master timer knob switch was in series with a single-pole double solenoid.
