THE CONDENSER TUMBLE DRYING PROCESS
The drying process is by means of a closed air system driven by a circulating fan. Air is drawn
internally from the rear of the outer drum, passed over a heating element and returned to the front of
the drum via an inlet through the door seal. The warm air travels through the wash load collecting
moisture, the moist air then condenses on a stream of cold water running down the inner rear section
of the outer drum. The relatively dry air is then drawn back over the element to repeat the process.
The circulating fan, one shot cut-out or thermal fuse cable along with a thermistor to control the air
temperature are located in a heater box assembly attached to the top of the outer drum.
The airflow passes through a filter located within the air duct from the outer drum to the heater box
assembly. At the start of every drying program the filter is automatically cleaned by flushing water
through it by means of a fill valve wired in parallel with the hot fill valve for 5 seconds duration.
