6. TROUBLE DIAGNOSIS

6-1. TROUBLE DIAGNOSIS

- As the micom wash machine is conﬁ gured 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 poten

difference of the human body and wash machine by contacting the power supply plug when work contacting to PCB is executed.

2) Since AC 220~240V 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 op erated normally.

13-2. TERMINOLOGY

1) ASSY-MAIN PCB (Imbalance Sensor) → To prevent the laundry from gathering on one side of the tube causing noise and vibration, the washing machine uses an imbalance detection device that evenly disentangles the laundry before the hydrating cycle starts.

2) DOOR-LOCK S/W → Prevents the door from being opened while a cycle is in progress. For safety purposes, it keeps the door locked even in pause mode or after the washing cycle unless the water level frequency is greater than 24.8Khz (anti-overﬂ ow level) or the inside-tube temperature is less than 65ć in the hydrating cycle, and 55ć in the washing cycle.

3) SENSOR-PRESSURE (Anti Over-Flow) → When the water supplied is more than 2/3 of the tube capacity due to a malfunction of the water supply valve, this device automatically starts water-draining and displays “OVER- FLOW ERROR(OE)” on the LED.

4) ASSY-THERMAL FUSE (Anti Over-Heat) → When the washing heater is overheated due to an error in the thermistor or any other malfunction, the assy-thermal fuse (built in the heater) is automatically activated to discon nect the power for your and the product’s safety.

5) ASSY-MAIN PCB (Sensitive Laundry Protection) → To avoid any damage to sensitive laundry, the tube temperature is detected and “ERROR(CE)” is displayed on the LED for Wool or Lingerie courses when the temperature is over 50ć.

6) THERMOSTAT (Anti Over-Heat) → When the heater (drier) overheats from an error in the thermistor or any other malfunction, the thermostat (installed on the drying duct) is automatically activated to disconnect the power for your or product’s safety

7) CHILD LOCK → Prevents children from playing with the washing machine.

8) PRE-WASH → The machine does a preliminary wash of about 10 minutes prior to the main wash. This is particularly effective for cleaning badly stained laundry.

9) WEIGHT SENSOR → The tube automatically rotates when no water is supplied to detect the laundry weight so that the proper wash time can be determined. (Standard, Boiling, Economy Boil and Dirt courses and Toweling and Drying cycles)

To reduce the risk of ﬁ re, electrical shock, and other injuries, keep these safety precautions in mind:

. Operate the appliance only from the type of power source indicated on the marking label. If you are not sure of the type of power supplied to your home, consult your appliance dealer or local power company. . Use only a grounded or polarized outlet. For your safety, this appliance is equipped with a polarized alter nating current line plug having one blade wider than the other. This plug will ﬁ t into the power outlet only one way. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug still doesn’t ﬁ t, contact your electrician to replace your outlet. . Protect the power cord. Power supply cords should be routed so that they are unlikely to be walked on or pinched by items placed on or against them. Pay particular attention to cords at plugs, convenience re ceptacles, and the point where they exit from the unit. . Do not overload the wall outlet or extension cords. Overloading can result in ﬁ re or electric shock.
