A magnet is embedded in the edge of the upper cover of the washing machine, and the corresponding position inside is a reed switch. The device is a protective device designed to prevent the dehydration barrel from opening the upper cover of the washing machine by mistake when rotating, so as to avoid the danger of loosening. After a long time, the magnetic steel will be seriously corroded or simply turned into oxidized powder, thus losing its original magnetic function and unable to transmit the information that the upper cover of the washing machine has been closed to the microcomputer control system. The circuit of the protection device is in an open state, even if you have covered the cover, it will cause an error message that the cover is not covered properly, resulting in abnormal operation. Solution-just replace a new magnetic steel at the two plastic interlayers on the edge of the cover.
