Key switch can not lock three important issues

First of all, on the basis of understanding the structure of the self-locking switch, find out the reasons why it cannot be self-locking and carry out maintenance. Possible failures are:
(1) The steel needle in the self-locking switch is released from the sliding block slot, so that the switch cannot be self-locking, and the self-locking switch needs to be disassembled to reinstall the steel needle;
(2) There are too many flashing edges in the sliding block in the self-locking switch, which causes the switch steel pin to be in place, so that the self-locking switch cannot be self-locking. It is necessary to disassemble the self-locking switch, take out the sliding block, and use the flying edge in the slot. Repair the knife, taking care not to damage the groove;

(3) The parts in the self-locking switch are damaged due to long-term use or other reasons, and the parts or the entire self-locking switch need to be replaced.
Secondly, in the case of urgent need, the self-locking switch can be temporarily pressed with a heavy object so that it can no longer be returned to the initial position and is in the ON state, and the washing machine can work.
Finally, use a screwdriver to unscrew the control seat fastening screw, remove the control seat, and replace the new self-locking switch.
