Method of Repair
1. Remove the two screws used to fix the Back Cover
- Remove the Back Cover
- Remove the Cap at ( 가 ) region
2. Remove the connection wire
- Separate the Thermostat fixed on the lower part of
the Tub by inclining the set 30° backwards.
(Beware of any remaining water while handling)
Ensure that the Thermostat is separated first and then
the Heater. If they are disassembled/assembled in
reverse order, this may result in electrical shocks from
the Thermostat.
3. Insert the M10 tool into the hole of the ( 가 )region,
unscrew the nut used to fix the Heater, and then
separate the Heater.
(Do not remove the nut completely, simply unscrew it to
the final thread. You can then pull the Heater forward.
Don't use any tools such as a nipper at this time. Draw
it out by shaking it a little with your hands, since the
Heater may give off small electrical shocks.)
4.Draw the Heater out of the Tub
※ Caution: During Assembly
In order to assemble it, place the Heater accurately on
the Tub Bracket. A wrong insertion may cause fire.
Insert the packing part completely into the inside of the
tub, just enough to adhere close to the tub. Tighten the
fixing nut with the force of 5kgfcm. A loose fixation will
cause water leakage.
Check Trouble Points
1. Check whether the resistance values of the Heater
reach 27.1 Ω (1900Wset) and 26.2 Ω (2000W set).
2. Check whether the resistance value of the Thermister
reaches 12k Ω (at room temperature).
