There is no hot
water or the
heating system
stays cold.
There is no voltage at the
appliance.
Check the fuses/MCBs in your
fuse box/distribution panel.
If required, reset the MCBs. If
the MCBs trip again after being
reset, notify your contractor.
The appliance
leaks water.
The condensate drain
may be blocked.
Call your contractor to have the
condensate drain cleaned out.
Condensate is
collecting on the
outside of the
appliance or the
air hoses.
The drying out phase of
the building is not yet
complete.
If the room is sufficiently well
ventilated or dehumidified,
this condensate should no
longer form on the appliance ap-
prox.two years after the house
was built.
The humidity in the air is
relatively high (≥60%).
When the weather conditions
change, condensation should no
longer form on the appliance.
The appliance is located
in a moisture-prone
area. Moisture-prone
areas are rooms where
the humidity in the air is
high due to the drying of
laundry, for example.
Make sure that the room is
adequately ventilated and dehu-
midified. If necessary, hang your
laundry up in a different room.
Use a vented tumble dryer.
Please note that condenser
tumble dryers do not reduce the
humidity in the air.
The air hoses are incor-
rectly fitted or sealed.
Cold air escapes.
Check whether the air hoses are
correctly fitted and sealed. If
necessary, call your contractor.
If you cannot remedy the fault, notify your qualified contractor.
