Fault finding
Gas operation
Symptom Cause
When switching on, the heat-
er does not operate.
– No 12 V supply voltage.
Check the power supply (operation voltage min. 10.5 V).
Check the Truma UltraRapid HWS fuse (refer to maintenance
“Fuses”).
When switching on, the heat-
er does not operate and the
red lamp lights up
after approx. 30 secs.
– Cowl cover fitted.
– Air in the gas supply.
– No gas supply.
– Incorrect gas pressure.
Remove cowl cover and / or clear any obstruction.
Check gas valves and gas cylinder.
To unlock (and purge air), switch off the appliance, wait
5minutes, and switch on again.
Heater operates for a pro-
longed time and then
the red lamp lights up.
– Excess temperature
thermostat has responded.
Check water level, refill if required (close drain valve).
To unlock, switch off the appliance, wait 5 minutes, and
switch on again.
Electrical operation
Symptom Cause
When switching on, the
heater does not operate.
– No 240 V supply voltage.
– Excess temperature
thermostat has responded.
Connect the caravan to the site supply and / or check residual
current circuit breaker.
Check water level, refill if required (close drain valve).
The electrical heating element is fitted with an excess tem-
perature cut-out. In the event of a fault, switch off at the
control panel, wait 10 minutes, then switch on again.
Water supply
Symptom Cause
Water drips from the
P&T safety valve.
– Water pressure to high.
– Lime or dirt under the
P&T safety valve seat.
Check water pressure (max. 400 kPa), use a pressure reduc-
er when connected to central water supply.
Allow the appliance to cool and then slowly raise the test
lever (Fig. 2a – 4a) to flush the water system and attempt to
force dirt or foreign matter out of the P&T safety valve seat.
Replace P&T safety valve. This must be performed only by a
certified service technician.
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 instal-
lation instructions “Water connection”).
If fault persists, please contact the nearest Dometic Service.
