the cold water supply temperature
is too low.
The fuse in the house electrical in-
stallation has tripped/blown.
The appliance's automatic circuit
breaker has been tripped.
The power limit has been reached.
Water flow-rate is too high and/or
the cold water supply temperature

Remove the filter and either
clean it or descale it.
Set the temperature on the continu-
ous-flow heater to "max".
Reduce the flow-rate at the water
tap supply.
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.
Check the fuse in the house electri-
cal installation.
Get the appliance's automatic cir-

Check the flow-rate limiter or re-
place it with a smaller one.
Set the power selector switch to
suit the appliance.
After a few seconds, the continu-
ous-flow heater automatically goes
back into operation.
Reduce the water flow on the taps
until the desired water temperature
is reached.
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.
