2. Safety Devices ※ We adapt 5 safety devices for users to use this wash machine safely. 1) Balancing device (ASSY-Main PCB) → When the laundry is out of balance, to prevent the noises and vibrations, the unbalance detecting sensor helps the laundry laid even and continue the dehydating process. 2) Anti-over water supply device →...
5. Main function 1) Auto power S/W off function ● After power on, the auto power S/W off function automatically switches power off for you if you do not press selection button for 10 minutes. ● After selecting the function, the auto power S/W off function automatically switches power off for you if you do not press start/pause button for 10 minutes.

5. Main function 7) 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 9) 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. Under the course of Cotton, or Coloureds, if the supplementary water supply numbers become 3 - 4 times the function is going at default condition ( high water level ), if 1-2 below that is going at middle level, if 0 below low water level, heating hours and rinse hours depend on the above data.

5. Main function 11) Unbalance detecting & laundry balance positioning system ① Just before the hydrating process and just after reversal rotation for balancing laundry position, this function is carried out ② The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm for initial 6 sec ③...
6. Technical point 1) Motor on/off time at each course unit:sec Washing Rinse Course Motor r.p.m Cotton Coloureds Synthetics Delicates Wools Quick ※ Motor on/off time is measured in cold water, in heating time motor on/off time is 10 sec on and 5sec off in the cotton course, beside cotton course, in the other course motor on/off time is the same with that of cold water use.

7. General Error Function When an error occurs, this function starts to keep generating error melody sounds and displays error indicators as shown in the followings per corresponding error by blinking in 0.5sec interval until the error status is completely cleared out. In this case, all the driving devices are turned off until the error is cleared out.

7. General Error Function 10. Tacho Error - This error occurs in case motor tacho is out of order or tacho siganals inputted are fewer than 2 - "EA" displayed - This error can be cleared by power s/w off 11.
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. 1) As some electronic components are damaged by the charged static electricity from the resin part of wash machine or the human body, prepare the human body earth or remove the potential difference of the human body and wash machine by contacting the power supply plug when the work contacting to PCB is...
