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
after switching the system back
on.
Water is leaking
from the appli-
ance.
The condensate drain
may be blocked.
Call your qualified contractor
to have the condensate drain
cleaned out.
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%).
Condensation should no longer
form on the appliance once
the weather conditions have
changed.
The appliance is sited in a
damp room. Damp rooms
contain increased levels
of humidity, forexample
because they are 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.
Note
Even when the condensate is draining away correctly, it
is not unusual for water to drip from the appliance onto
the floor.
If you cannot remedy the fault, contact your qualified contractor.
