Indication Cause Measure
Water leakage There is a leakage from a threaded
water connection. Tighten the threaded connection.
There is a condensate leakage Make sure that the condensation water
discharge is working properly.
If necessary, correct the water discharge.
There is a leakage from another nearby
water heater or pipe segment. Trace the leakage.
There is a leakage from the water heater
tank. Contact the supplier of your water heater.
Explosive ignition The gas supply pressure is incorrect. Check the gas supply pressure, refer to Gas
supply pressure (see 8.9.3).
The CO
2
value is incorrect. Check the CO
2
value, refer to CO
2
value
(see 8.9.4).
The burner is contaminated. Clean the burner, refer to Gas-side
maintenance (see 11.4).
There is an air leakage between the
venturi and the flexible air connector. Make sure that:

230 V
AC
(-15%, +10%).
