2. EXPLANATION OF CIRCUIT
• The MICOM terminal No. 13 gets into 'L' at the state of the closed door. If the door is opened in spining stage, the
MICOM generates error signal. (See page 27)
• Case of range 40 mSEC~300 mSEC in spining time: It is regarded that washing clothes should be inclined.
Accordingly washing time increases 8 minutes and rinsing action takes place another one time. Case of above 400
mSEC: It is regarded that the door should be open. Therefore it is displayed as door open error. (See page 27)
3. CAUTION FOR A/S
• Be level with the ground.
• The UNBLANCE error occurs in case of not being level with the ground.
• The waveform between the MICOM terminal No. 13 and the GND.

2. EXPLANATION OF CIRCUIT
• Detecting the voltage of running condenser, it sends the sensing data to the MICOM terminal No.35 & 36. That is, as
charging & discharging time of running condenser becomes different according to the loads, in fuzzy course the
washing time is determined by sensing the quantity of washing clothes.
