and flow rate
The greater the flow rate of the hot water, the
cooler the water.

• Troubleshooting
1) Water flow becomes weaker:
see chapter Cleaning and maintenance –
The filter
18
the aerator
11
.
2) The water does not heat up
(no display):
the mains plug is not correctly seated in the
socket – correct the position of the mains
plug
3) The socket is faulty – try another socket:
there is no mains voltage –
Check the fuse in the fuse box
4) The water only reaches lukewarm temper-
ature
(despite the display):
reduce the water flow/flow rate in the hot
water range
5) Fuse in fuse box has tripped:
Too many devices in a circuit – reduce the
number of connected devices.
