TROUBLE DIAGNOSIS
-
As the micom wash machine is configured of the complicate structure, there might be the
service call.
Below information is prepared for exact trouble diagnosis and suitable repair guide.
Caution for the Repair and Replacement
Please follow below instruction for the trouble diagnosis and parts replacement.
1)
As some electronic components are damaged by the charged static electricity from the resin
part of the machine or the human body, prepare the human body by grounding it to the earth
or remove the potential difference of the human body and machine by contacting the power
supply plug when contact to the PCB is executed.
2)
Since AC120V is applied to the triac T1 and T2 on P.C.B, the electric shock may occur by touching
and be careful that the strong and weak electricity are mixed.
3)
As the P.C.B assembly is designed for no trouble, do not replace the P.C.B assembly by the wrong
diagnosis and follow the procedure of the trouble diagnosis when the micom is not operated
normally.
To avoid risk of electrical shock, personal injury or death; disconnect power to washer
before servicing, unless testing requires power.
