replace the heating element
Electric heating element
noisy
Anomalous level of water
hardness.
Water causing scaling.
Scale on the heating element causes an uneven and violent heat
exchange in the places where it has come off. The definitive solution is
to install a water softener (A dispenser may not be sufficient).
Dripping from water safety
unit
Internal pressure greater than or
equal to 0.7 Mpa (7 bar). (Often
due to normal water expansion
during heating)
The system cannot “absorb” the water expansion in heating. To avoid
dripping install an expansion tank or connect the safety valve to a drain.
See the relevant section “Dripping from water safety unit” and
“Expansion tank”.

Dripping can occur if the water in the tank is cold. Always check for
leaks with the water hot.
