6. Troubleshooting
fault
Cause
remedy
There is no hot
water or the hea-
ting system stays
cold.
There is no voltage at
the appliance.
Check the fuses/MCBs in your
fuse box. Replace the fuses/reset
the MCBs if required. Notify your
contractor if the fuses/MCBs
blow/trip again.
Water is leaking
from the appliance.
The condensate drain
may be blocked.
Clean the condensate drain as
described in chapter „Main-
tenance and care“.
Condensate is
collecting on the
outside of the ap-
pliance.
The heat pump is dra-
wing heat from the
outdoor air to heat
the building. This can
cause the humidity
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.
