Troubleshooting guide

Fault
Water not getting hot.
Water taking an extremely
long time to heat up.
Water running away – boiler
cannot be filled
Boiler cannot be drained,
even though the safety/drain
valve is open.
Water dripping out of drain-
age socket of safety/drain
valve.
If these actions do not remedy the problem, please contact Truma Service.

Start-up

The boiler must not be operated with a time switch.
230 V ~
Figure 2
c = Toggle switch "On"
d = Toggle switch "Off"
Switch on boiler at control panel (c). The indicator light indi-
cates that the device is operating.
Use of vehicle-specific switches: see operating instructions
from vehicle manufacturer.
The water temperature cannot be preselected, auto-
matic temperature limit at approx. 70 °C.
The electric heating element is equipped with overtem-
perature protection. If the device is operated without
water, the overtemperature protection switches it off at 90 °C.
In order to switch it on again, the device must cool to less
than 24 °C and be switched "Off" and "On" again (Reset).

Cause
– No operating voltage.
– Operation without water;
overtemperature protec-
tion switching heating ele-
ment off.
– Water container furred.
– Safety/drain valve is open.
– Drainage socket of safety/
drain valve closed.
– Venting hose closed off.
– Elbow fitting twisted at
boiler.
– Water pressure too high.

Remedy
– Restore power supply.
– Switch off, wait for 10 minutes, fill with water, switch on.
– Descale water system (see maintenance).
– Close safety/drain valve.
– Check opening for soiling (slush, ice, leaves etc.) and re-
move if necessary.
– Check opening (see above).
– Check hose for kinks and correct.
– The aeration valve on the elbow fitting must face to the side.
– Check pump pressure (max. 2.8 bar). If the boiler is con-
nected to a central water supply (rural or urban connection),
a pressure reducer must be used, which will prevent pres-
sures higher than 2.8 bar from occurring.

Maintenance

Only original Truma parts may be used for maintenance
and repair work.
We recommend the use of suitable commercially available
products to clean, sterilise and maintain the boiler. Products
containing chlorine are not suitable.
The boiler should be heated to 70 °C at regular intervals to
prevent infestation by microorganisms.

Disposal

The device must be disposed of in accordance with the ad-
ministrative regulations of the respective country in which it is
used. National regulations and laws (in Germany, for example,
the End-of-life Vehicle Regulation) must be observed.
In other countries, the relevant regulations must be observed.
