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 board.
The flow rate is too low
for switching on the
heating output. The aer-
ator in the tap is scaled
up or dirty.
Clean and/or descale the
aerator.
