3.3. Methods of determining the most complex defects. Repair of washing machines with complex defects.

3.3.1. Before you start disassembling the entire machine or its individual components, necessary to determine the defect location. Feature of wiring is, that all supply chain components (dvigaetl, electric heater, solenoid, etc.) pass through the plug, cord, hatchway locking apparatus MR (or microswitch IP), pressure switch P and contacts of controller T. Similar features require the use of certain methods of search of faults in the wiring diagram of the machine. The study chain, in which a defect is supposed (It is defined according to a list of possible faults), razvryvaetsya removable by disconnecting the contacts of the connecting wires of controller contacts. Next, the integrity of the electrical circuits or special probe ohmmeter, both of controller, and harness with hardware products. Here is the procedure for determining the causes of malfunctions in the most typical cases.

3.3.2. Drum drive motor hums, but the drum does not rotate. Recommended search sequence and washing machine repair

Check the rotation of the drum drive motor when it has to rotate in both directions (pulse 4), then in the extraction mode 500 rev / min (pulses 36)
Based on the behavior of the motor in different modes to determine the faulty circuit and check, determining the presence of voltage on the conclusions of the components.

3.3.3. Water does not fill the tank. Repairs to the washing machine next:

Check the voltage on the valve spool (pulses 1, 5, 34). In the absence of stress test pins of controllerL-M (or 8-6). Check the integrity of the electric circuit PS and the presence of the contact is closed 11-12 pressure switch P1.
on pulses 1, 5, 34 check pouring water over a respective tray (preliminary, basic, spetsobrabotka). In the case of water pouring inconsistencies check the water distribution mechanism for rice. 3 pos. 7-10, 37, 39, 40, 41.

REPAIR WASHING MACHINES

Description of the work performed for the first program of SMA model WN463WDZ. (cm. sequence diagram operation CMA).

Handle selection programs are putting the program “1”, selection knob temperature chosen wash temperature (eg 90° FROM). Press I1 “Net” turn the machine to the network. indicator lights “Net”.

Pulse 1. Prewash

Through the closed contacts 1-2 button I1, contact microswitch IP, closed contacts 21-22 pressure switch P2 and contacts L-M of controller T (hereinafter referred to as k / a) voltage is applied to the solenoid coil pouring water Evfa. The valve opens and the water flows into the tank. When filling the tank with water to a level pressure switch P2. Contacts 21-22 pressure switch P2 opens, power is removed from the winding Evfa, the valve closes, cutting off the water supply to the tub. Contacts 21-23 P2 pressure switch opens and the voltage across the closed contacts R-T k / a falls on the motor drive k / a MT and contacts 4 motor ML drum drive. Through the closed contacts E-D k / a, 7-15 k / a, 12-5, 9-13 (or 9-14) k / a voltage supplied to the terminals 6, 3 drum drive motor ML. It begins rotation of the drum in both directions alternately. Reversing makes contact 9-13 (9-14) k / a (fast cam) when the motor MT.
