Following an interruption of the water supply
!
Material losses
Following an interruption of the water supply, the
appliance must be recommissioned by carrying out the
following steps:
Disconnect the appliance from the power supply by
removing the fuses/tripping the MCBs.
Open the tap for one minute until the appliance and
its upstream cold water inlet line are free of air.
Switch the mains power back ON again.
5. Cleaning, care and maintenance
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Check the taps regularly. Limescale deposits at the spouts
can be removed using commercially available descaling
agents.
6. Troubleshooting
Problem Cause Remedy
The appliance will not
start despite the DHW
valve being fully open.
There is no power.
Check the fuses/MCBs in
your fuse box/distribu-
tion panel.
The flow rate is too low
for the appliance to start
heating at the selected
output. The aerator in
the tap or the shower
head is scaled up or con-
taminated.
Clean and/or descale the
aerator or shower head.
If you cannot remedy the fault, notify your qualified contractor.
