V.5 Boiling noise
Action to take
Solution
Cause
1. Check that the noise occurs when
the water heater is in the process of
heating.
If the noise occurs during heating,
descale the water heater (see Chap-
ter 7.3 maintenance p.30).
Water heater is scaled up.
If the noise does not occur during
heating or it consists of clicking
noises, or it occurs when the valve
is turned on, consult a plumber so
that they can find the cause of the
problem.
The water heater is not the cause.
