TROUBLESHOOTING

Your appliance is designed and manufactured for a long life and reliable operation.

If a problem occurs during operation, check whether it is due to an operating error. Please note

that even during the warranty period, some repair costs may be your responsibility.

You may be able to correct the following faults by checking the possible causes yourself:

Problem	Possible Cause and Remedy

Appliance does not work,	- Is the appliance turned ON properly?
display is OFF	- Is the power source plug properly inserted in the socket?
	- Is the circuit breaker or fuse in operating condition?

The interior light does	- Is the refrigerator compartment turned ON?
not come ON	- Has the door been open for more than 15 minutes?
	- The bulb is defective. Change the bulb as described in Interior light.

Loud running noise	- Is the appliance standing firmly on the floor, or does the compressor
	cause nearby items of furniture or objects to vibrate? If necessary, move
	bottles and containers apart.
	- Bubbling noises are normal. These are caused by the refrigerant
	flowing around the refrigerant circuit.
	- A short clicking sound: This will be heard whenever the compressor
	turns ON or OFF automatically.
	- Motor noise: This will be slightly louder for a brief period when the
	compressor turns ON. The refrigerating capacity will increase when
	the SuperFrost function is activated, fresh food has just been placed in
	the appliance or the door has been left open for a while. A low-pitched
	humming sound is caused by air flow noises in the fan.

The compressor continues	On energy saving models, this is perfectly normal. When less refrigeration
to run for a long time	is required, the VCC compressor switches to a low speed. It will run almost
	constantly, but it still saves energy.

	- Is the appliance sufficiently ventilated? Clean ventilation grilles if
	necessary.
	- Is the ambient temperature too hot? See Safety Regulations.
	- Has the appliance been opened too often or left open too long?
	- If applicable, wait until the appliance reaches the required temperature itself.
