  • Page 19 Part Figure Description 1. Unfasten the 4 screws that hold the back cover in place. Remove the back cover by sliding it down. (When assembling, slide the back cover up.) 2. After removing the back cover, unfasten the M19 nut that holds the motor in place. Caution Turn the nut counterclockwise to unfasten it. You have to turn it with a quick ‘twist’ because turning it slowly turns the motor at the same time and makes it difficult to loosen the nut. Do not try to unfasten the nut by inserting a screw driver into the motor. This may cause a motor malfunction. 3. Remove the M19 nut washer and then remove the rotor. Caution Pulling out the rotor requires some force and is pulled out suddenly rather than slowly. Be careful, as the stator when pulled out, may cause damage to the corners of DD Motor the frame, or injury to your hands or arms. 4. Unfasten the six (6) M10 screws. → Remove the assy bracket motor. → Remove the stator. When unfastening the last one of the six (6) screws, hold the stator by hand to prevent it from falling due to its weight. 5. Remove the motor wire and hall sensor while Motor wire holding down the navel of the housing.

You cannot remove the PCB separately because urethane is used for water proofing. 4 Check Points for Troubleshooting 1. Check whether there is any error in applying the power. 2. Check the voltage between the DC 5V and GND terminals. 3. If an error occurs when there is no characteristic error in the electric harnesses, check these points: 3E error: The resistance of motor(U-V/V-W/W-U) is 5 Ω HE/HE1 error: The resistance of heater(for 1900W unit) is 27 Ω DE1 error: The resistance of door switch is 140 to 145 Ω HE/HE1 error: The resistance of thermostat is 0 Ω 5E error: The resistance of drain motor is 400 Ω 4E error: The resistance of water valve is 4.4 kΩ Reassembly is in the reverse order of the removal.
