Warning

While Servicing

ࣃ Check if the power cable is damaged, attened, cut or otherwise degraded.

ࣃ If faulty, replace it immediately.

 Failing to do so may result in electric shock or re.

ࣃ Completely remove any dust or foreign material from the housing, wiring and connection parts.

 This will prevent a risk of re due to tracking and shorts in advance.

ࣃ When connecting wires, make sure to connect them using the relevant connectors and check that they are completely connected.

 If tape is used instead of the connectors, it may cause re due to tracking.

ࣃ Make sure to discharge the PBA power and capacitor terminals before starting the service.

 Failing to do so may result in a high voltage electric shock.

ࣃ When replacing the heater, make sure to fasten the holder heater after ensuring that it is inserted into the bracket- heater.

 Ensure the heater is tted into the bracket - heater correctly.

ࣃ Ensure that the heater is inserted into the heater bracket rst and then tighten the heater holder.

Caution

After Servicing

ࣃ Check the assembled status of the parts.

 They must be the same as before servicing.

ࣃ Check the insulation resistance.



Disconnect the circuit breaker or power cable from the power outlet and measure the insulation resistance between the power

wires and the grounding wire of the dishwasher. The value must be greater than 10MΩ when measured with a 500V DC Megger.

ࣃ Check whether the product is level with the oor. Check if there are any deformations in the sink.

Check that the dishwasher is rmly installed to the sink.

 Vibrations can shorten the lifetime of the product.

Caution

Electrical Safety Test

ࣃ Before servicing any home appliance, it’s the best to perform a complete electrical safety checks to conrm the product is safe to

handle. Tests like earth-continuity, insulation-resistance (using a megger where appropriate), and basic voltage or polarity checks with

a standard meter verify that the appliance has no hidden electrical faults that could pose a risk during repair.

These checks ensure proper grounding, conrm there is no breakdown in insulation, and validate that the electrical path is stable and

secure. Performing these tests rst protects both the engineer and the customer, ensuring the appliance is electrically healthy before

any service work begins.

ࣃ Performing the Outlet test (where you are allowed to) helps with dening any potential issues in the environment and helps you with

better diagnosis and reduces the chance of redo due to external factors.

ࣃ Make sure your test devices are following the required standards, have fully charged battery, are calibrated and always use

manufacturer-approved accessories such as test leads, probs and clips.

ࣃ Having a “DO NOT USE” sticker can help you and customers to dene a faulty appliance and keeps everyone safe.

Circulation motor

A motor that sucks the water remaining on the oor of the dishwater and injects

water using high pressure through the internal water passages to the top.

Middle and lower nozzles.

Drain pump

The pump that drains the polluted water from the dishwater generated while the

dishwater is running.

Heater

The heater is located on the water passages inside the dishwasher.

It heats the owing water to increase wash efciency.

Flow meter

Measure the amount of supplied water by counting the pulses of the hall IC located

at the next of the inlet valve.

Distributor

Located at the output end of the sump inside the dishwasher. It turns the ow of the

water that goes to the bottom part of the dishwasher on or off.

(THIS MODEL DOES NOT HAVE THIS PART)

Dispenser

The location where the detergent and rinse aids are stored so they can be used by

the dishwasher. The dispenser automatically supplies detergent and rinse aids to the

inside of the dishwasher when they are needed.

Tub Assy

An internal case mode of stainless steel that makes up the basic framework of the

dishwasher.

Sump Assy

The place inside the dishwasher where water is collected. The injected water gathers

here after circulation. The sump Ass’y is connected to the circulation motor and drain

pump.

Door Assy An internal case made of stainless steel that makes up internal part of the front door.

Base Assy A plastic part that makes up the basic bottom framework.

Basket Assy The upper and lower racks where dishes can be loaded.

Top/Middle/Lower nozzles

Washes dishes by rotating and injecting the supplied water through the water

passage at high pressure.

Case brake

A passage that adjusts the air pressure by connecting the pressure of the inside air

which is expanded at high temperature during wash and rinse cycles and the outside

air pressure.
