Notes on Repair and Disassembling

Make sure to observe the followings when carrying out failure diagnosis and replacing parts.
(1) Unplug and wait for 10 seconds before starting operation. (This machine is equipped with a large-
capacity capacitor.)
(2) To prevent damage on electronic components due to static electricity charged in human body or resin
part of the washing machine, eliminate potential difference between human body and washing machine
by using a body earth or by touching the earth wire before performing any work that involves contact to
the program timer.
(3) Electronic components on PCB cannot be replaced as the program timer is protected by a humidity
proof coating to increase its humidity resistance. Replace the whole program timer unit. Care should be
taken for handling of the humidity proof coating to avoid damage.
(4) Both strong electricity (AC0V, DCV) and weak electricity (DC17V) exist inside the panel.
Take due care to avoid electrical shock due to careless handling.
(5) Care should be taken to avoid burn as the heat sink of the program time becomes hot immediately after
use.
<Replacing Water Supply Valve and Water Dispenser Case>
This series adopted the structure where the water supply valve is directly connected to the water dispenser
case.
When replacing the water supply valve, make sure to use the O-ring provided. Use of old O-ring could
result in water leakage.
After removing and reattaching the water dispenser case, make sure to carry out trial run before installing
the back cover to make sure that water does not leak from any joint.
