Washing machine is in use process all of a sudden halt, burning in the "buzzing" sound well geared. Fingerprint motor special hot; Start measuring capacitance C did not see damage, capacity, reduce the phenomenon; Disassemble the motor, found the black line around the group more than burn out. Or not to replace the motor after electrify, motor, and the "buzzing" sound is very big. The ends of the table was used to measure the capacitance C 220 v, therefore conclude that control circuit fault (related circuit as shown). Open washing machine panel, after check, triode, V1 and V2 control circuit breakdown short circuit. Remove the damaged components, using two models for 8050 after the replacement of the triode, troubleshooting.Bftservice manual download site
