Air Duct (NTC)
System Thermistor
Compressor Cooling Fan
The cooling fan is located on the RH side at the front of the base moulding immediately behind the
air inlet grill. The fan is controlled by the system pipe work NTC and operates when the NTC senses
a temperature of approximately 53°C on Cotton and Synthetic programmes and 45°C on Delicate
Programmes. The fan will start after about 20 minutes and will switch on intermittently during the
early stages of the Drying cycle.
Compressor
The compressor starts running at the beginning of the programme selected and will run continually
for the duration of the drying programme switching off during cool tumble.
If the power supply to the compressor is interrupted (i.e. if the door is opened) there will be a 5 minute
delay before power is restored, this delay is to enable the refrigeration system to equalise.
Operation of the Float Switch:
The compressor will turn off after
approximately 1 minute, and the machine
will continue, with cool air only for a further
10 minutes, before the warning H20 is
displayed, the Start/Pause button flashes
orange and the empty water container
icon flashes.
Located in the front air duct, this thermistor continually
monitors the temperature of the circulating
drying air.

The system thermistor sits in a pocket on the external
system pipe work, and measures the system
