Servicing shall be carried out only by authorised personel.
Please contact Dometic Service Centre for service and repairs.
Biofilm, deposits and limescale must be removed using chemicals to
protect the unit from infestation by microorganisms. Only chloride-
free products must be used in order to prevent damage to the unit.
The effectiveness of the use of chemicals to combat microorganisms
in the unit can be increased by heating the water in the boiler to 70
°C at regular intervals.
– Select “Gas” mode.
– Set water temperature to 60 °C. –
Switch on device.
Once the water in the boiler has reached a temperature of 60
°C, the burner will switch off. The unit must stay
switched on for at least 30 minutes and no warm water may be
removed. The residual heat in the heat exchanger will heat the water
up to 70 °C.
Fuses
Fuse 12 V
The fuse is in the electronics beneath the connection cover. Replace
the unit’s fuse only with an identical fuse.
Device fuse: 10 A – slow – (T 10 A)
Fig. 4
Fuse 240 V
The fuse and the power supply lines must only be replaced by an
expert!
The unit must be disconnected from the mains (all poles)
before opening the electronic housing lid.
The fuse is in the power electronics (16) beneath the electronic
housing lid.
This fine fuse must always be replaced with a fuse of the same type:
10 A, slow, interrupting capacity “H”.

Overheating protection 240 V
The 240 V heating facility has a mechanical overheating switch. If the
12 V power supply is interrupted during operation or during the
after-run period, for example, the temperatures within the unit could
activate the overheating protection.
Fig. 6
To reset the overheating protection, allow heater to cool, remove
connection cover and press red reset button.
Faults
Faults – Heater
Descriptions of possible fault causes and a troubleshooting guide
can be found in the operating instructions for the control panel
that is installed.
Faults – Water supply
Possible fault causes and a troubleshooting guide – See
“Troubleshooting guide (water supply)”.
Troubleshooting guide (water supply)
Water taking an extremely long
time to heat up.
Water container furred. /
Descale water system (see
“Maintenance”).
Water running out, cannot fill
boiler.
Safety/drain valve open. / Close
safety/drain valve.
Cannot empty boiler, even though
safety/drain valve is open.
Safety/drain valve draining
connection blocked. / Inspect
opening for contamination (slush,
ice, leaves, etc.) and remove
contamination if necessary.
Water dripping/flowing from
draining socket of safety/ drain
valve.
Water pressure too high. / Check
pump pressure (max.
0.28 MPa). If connected to a
central water supply (rural or
urban connection), a pressure
reducer must be used, which will
prevent pressures higher than
0.28 MPa entering the boiler.
When opening the cold water
tap, hot water comes out.
Hot water flows back through
the cold water supply. / Fit a
non-return valve in the cold
water supply (refer to
installation instructions “Water
connection”).
If these measures do not remove the failure, please contact the
nearest Dometic Service.
