7.5 Inside of the tank
The storage of water at high temperatures and the characteristics
of the water itself can cause a layer of scale to build up on the
surface of the electric heater and/or the accumulation of detritus
in the interior of the tank, affecting mainly:
• water quality
•power consumption
• appliance functionality
•appliance service life
Amongst other things, the abovementioned consequences lead
to a lower thermal transfer between the heater and the water,
causing the thermostat to start/stop more frequently, higher
power consumption and potential safety activation if
temperature limits are breached (manual resetting of
thermostat necessary).
For optimal functioning, the following recommendations
are made:
Clean the interior of the tank.
Clean the electric heater (descale or replace).
Inspect the magnesium anode.
Replace the sealing collar of the flange.
The abovementioned interventions are not covered by the
appliance warranty.
7.6 Restarting after maintenance work
Tighten all water connections and check them for tightness.
Switch on the appliance.
