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.

Restarting after maintenance work

▶ Switch on the appliance.
