The appliance must be decalcified (refer to “Decalification”
on page 58).
Hot water
temperature too

Gas flow to the appliance is too
low (gas inlet pressure < 10.5 in.
wc).
Consult vehicle documentation to determine if the gas
supply is capable of providing the necessary volume of gas
for the appliance.
Contact a service technician to verify that the gas installation
is suitable
Volume flow of hot water is too
high and/or temperature of cold
water reaching the appliance is
too low
Turn down hot water at the faucet or in the shower in order
to reduce flow rate.
Potentially retrofit a flow rate throttle in the water system.
This must be performed by a certified service technician.
Too much lime scale in the
appliance.
The appliance must be decalcified (refer to “Decalcification”
on page 58).
Water escaping
at pressure relief
valve.
Water pressure in water system
too high
Adjust the water pump pressure to a maximum of 65 psi (4.5
bar). If the water system is connected to a central water
supply higher than 65 psi (4.5 bar) (rural or urban
connection), a pressure reducer must be used.
Install a pressure reducer (e.g. Truma pressure reducer) at the
fresh water supply.
Water cannot expand in the water
system.
Contact the vehicle manufacturer about retrofitting a pres
-
sure compensation element.
Lime or dirt under the pressure
relief valve seat.
Allow the appliance to cool and then slowly raise the test
lever (Fig. 3 – 4a) to flush the water system and attempt to
force dirt or foreign matter out of the pressure relief valve
seat.
Replace pressure relief valve. This must be performed by a
Truma certified service technician.
Water escaping at

Lime or dirt under the O-ring
seats.
Clean the O-rings and their corresponding sealing
