Problem Potential Cause Resolution
No hot water at
the faucet Gas supply is turned off or
interrupted. Check and/or turn on gas supply.
Gas tank is empty Refill/replace the gas tank.
The appliance is switched off. Switch on the appliance according to instructions (refer to
“Operating procedures” on page 53).
Fresh water supply is turned off. Open the fresh water supply.
Power supply to the appliance is
switched off. Switch on power supply to the appliance.
Defect in the appliance. LED 2 flashes red (refer to “APPENDIX A - Error Codes”
on page 67) and contact a certified service technician if
necessary.
Boiling noises Too much lime scale in the AquaGo
instant water heater. The appliance must be decalcified (refer to “Decalification”
on page 61).
Hot water
temperature too
low 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 61).
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
pressure 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
water inlet filter Lime or dirt under the O-ring
seats. Clean the O-rings and their corresponding sealing surfaces
with clean water.
