REPAIR INSTRUCTIONS

GC7521

• Due to the high wattage of the iron, only the specified cord set must be used.

• Should damage be observed on the HOSE-CORD ASSY or CORDSET 55, they must be replaced.
Continued usage is not allowed.

• When replacing the MICROSWITCH ASSY 9, please dress the 2 attached wires such that they are free of tension.
Pulling force on the wires may affect the steam triggering.

• To avoid damage to the sealing & components of the BOILER ASSY 38, NEVER clean the boiler assy with vinegar,
descaling agent or other corrosive chemicals.

• When replacing ELECTROVALVE 40 or PUMP ASSY 45, please be reminded to apply loctite at the joints for good
sealing.

• After the product has been repaired, it should function properly and has to meet the safety requirements & legal regulations
as laid down & officially established at this moment.

• The following tests are common checks that are conducted on a repaired product before it is returned to the consumer.

1. Soleplate temperature

Check that soleplate temperature is within IEC requirement.

Measure the temperature of the soleplate after the iron has reached steady state i.e connected to the mains for at least
15minutes. The table below shows the temperature requirement.

Cotton, linen

2. Leakage current

Check that leakage current is within IEC requirement.

Measure leakage current between LIVE/NEUTRAL & EARTH.
IEC requirement is that at 230 V supply, the EARTH leakage current must be less than 0.75 mA.

3. Water leakage / Functionality

Check that there is no water leakage from any part of the product during operation.

Check that the functionality of the product (product dependent) eg. steaming, variable steam, SOS, ASO etc is working
properly.

4. Loose part

Check that there are no loose parts eg. extra screw in the product that can cause short-circuit or product malfunction.
