Change to Cold Fill and deletion of heater box fluff filter.
th
On 25
April 2005 (Date Code 40), this range of washer dryers changed from
Hot and Cold Fill to Cold Fill only. Along with this change a modification was
made to the tumble dryer heater box assembly with the introduction of a
straight heating element, this to improve the air flow through the heater box.
This change enables the removal of the heater box fluff filter and deletion of the
flushing valve and hose. The thermistor, one-shot cut out and fan assembly are
not affected. The 4-way valve is replaced by a 3-way valve and the hot supply
hose is deleted.
A new file setting (EEPROM) is used for cold fill machines but the consumer
programmes remain the same for both Hot and Cold and Cold fill machines, the
changes to the heater box assembly does not effect the EEPROM file settings.
All parts that are affected with these changes are listed on Partfinder along with
a Special Notice.
