Execute A/S after unplugging the power supply unit. ☞ Be care of the electric shock. 3. Do not plug several plugs in the same outlet. ☞ It may cause the fire due to overheat. 4. Check the damage, pressing or burning of the power plug or outlet. ☞ Replace it promptly if it has problem.(may cause the electric shock or fire) 5.
7. General Error Function 1. An occurrence of an Error will make a sound of error melody for 5sec and continuously show one of the Error Displays from the following errors. (But, Fault Check Led will flash for 0.5sec.) 2. All of the steering parts will be off at that time until that error was released. 3.
7. General Error Function 11. Natural Drain/Water Leak Error - If more than 4 times of water supply and safe water level of Heater are sensed for each course, this error will occur. - Display : "LE - This error will be released by turning off Power S/W. 12. Tacho Error - If Motor Tacho is abnormal, this error will occur. If Tacho signals are inputted less than 2 for 2sec after Motor started, this error will occur. Display : "3E" This error will be released by turning off Power S/W. 13.
8. 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.
8-1. Trouble Diagnosis No Item Cause and treatment The power is not supplied - Is the PCB connector connected well? - Is the voltage normal? - Is the power supply plug connected well? - Is the noise filter connected well? - Is the secondary output of the power supply transformation normal? - Is the fuse disconnected? (option) • If above points are not found, the PCB assembly is out of order. Replace it. The water is not supplied.

5. Main function 8) Power-out compensation function ● If power is out on selected process, the process before power out is stored to EEPROM, once power is back the process before power out continues. ● When power is back, washing process starts from the process at the point of the power out, rinse/drain process starts from the initial process.
5. Main function 10) Fuzzy washing function ( weight-sensing) ☞ After finishing initial water supply, when the fall of the water level needs supplementary water supply, Sensing function perceives the weight with the supplementary water supply numbers and starts to work.
