Problem solving guide
Problem
The heat exchanger
unit service panel
will not shut.
Water leaks from
the machine after
the heat exchanger
unit has been
cleaned.
Items made of
synthetic fibres are
charged with static
electricity after
drying.
There is a build up
of fluff.
36
Possible cause
The inner cover of the heat
exchanger unit has not been
locked properly and/or the
heat exchanger unit has not
been positioned correctly.
Fluff has collected at the
bottom of the condenser unit
housing.
Synthetic fibres tend to
attract static charge.
Fluff is principally the result
of friction when garments
are being worn and washed.
Machine drying hardly
causes any fluff to form and
has been established by
research institutes to have
no appreciable effect on the
lifetime of the garment.
Remedy
– Ensure that the heat
exchanger unit is
positioned correctly and
lock the cover.
– Check the rubber seals.
– Use a cloth to remove
any fluff from the inside
of the condenser unit
housing.
Static charge can be
reduced by adding a fabric
conditioner to the final rinse
in the washing programme
or a fabric conditioner sheet
to the load when drying.
Fluff is collected by the fluff
filters and can be easily
removed (see "Cleaning
and care").
