personnel.

Water flow-rate is too low. The filter in either the water tap or
the showerhead is clogged Remove the filter and either

The desired water temperature is
not reached. The continuous-flow heater is
connected to a thermostatically-
controlled water tap. Set the temperature on the continu-
ous-flow heater to “max”. Customer
The power limit has been reached.
Water flow-rate is too high and/or
the cold water supply temperature
is too low. Reduce the flow-rate at the water
tap supply. Customer
By a qualified professional:
use the angle valve to regulate the
flow-rate.
Check the flow-rate limiter or re-
place it with a smaller one. Servicing
expert
The water is not sufficiently warm. The fuse in the house electrical in-
stallation has tripped/blown. Check the fuse in the house electri-
cal installation. Customer

off. After a few seconds, the continu-
ous-flow heater automatically goes
back into operation. Continu-

Winter operation:
The desired water temperature
leaving the tap is no longer
reached. The supply temperature has
reduced. Reduce the water flow on the taps
until the desired water temperature
is reached. Customer
The appliance does not start
(heat), no water flows Power failure or initial start-up. Starts rinsing:
Open the warm water tap and
allow water to flow for at least
1 minute (flow-rate at least 6 litres
per minute). Only then (for safety
reasons) will the appliance begin
to heat.
Should the appliance not start
because of a reduced flow-rate,
remove the perlator, shower head
or similar before start and repeat
the process.
