fault
Cause
remedy
There is no hot
water or the
heating system
remains cold.
No power at the appli-
ance.
Check the fuses/MCBs in your
distribution board. Replace the
fuses/reset the MCBs if required.
Notify your qualified contractor if
the fuses/MCBs blow/trip again.
Water is leaking
from the appli-
ance.
The condensate drain
may be blocked.
Call your contractor to have the
condensate drain cleaned out.
Indoor installa-
tion: Condensate
is collecting on
the outside of the
appliance or on
the air hoses.
The drying out phase of
the building is not yet
complete.
This condensate should no
longer form on the appliance
after the house is approx. two
years old, providing the room is
sufficiently well ventilated and
dehumidified.
The relative humidity in
the air is high (≥60 %).
A change in weather conditions
should no longer cause conden-
sation to form on the appliance.
The appliance is sited
in a damp room. Damp
rooms are those where
humidity in the air is
high. They may, for ex-
ample, be used for drying
laundry.
Ensure that the room is ade-
quately ventilated and dehumid-
ified. If necessary, hang your
laundry in a different room.
Use a vented tumble dryer.
Please note that condenser tum-
ble dryers do not reduce the level
of humidity in the air.
The air hoses are incor-
rectly fitted or poorly
sealed.
Cold air is escaping.
Check that the air hoses are
correctly fitted and sealed. If
necessary, contact your qualified
contractor.
Outdoor installa-
tion: Condensate
is collecting on
the outside of the
appliance.
The heat pump is extract-
ing heat from the outdoor
air to heat the building.
This can cause the hu-
midity in the outdoor air
to accumulate as dew or
frost on the cooled heat
pump casing. This is not
a defect.
Note
Even when the condensate is draining away correctly,
expect water to drip from the appliance onto the floor.
If you cannot remedy the fault, notify your qualified contractor.
