WHAT TO DO IF ...
6 What to do if ...
6.1 ... there is no hot water
The tap is fully opened. In this case it could be that the water
heater has not heated the water because there is no power. Check
the MCB/fuse and residual current device in your fuse box.
6.2 ... the water fl ow rate is weak
It could be that the jet controller in the tap is contaminated or
scaled up. In this case clean the jet controller or descale it. You
can order the jet controller from us as a replacement part with
part number 279932.
6.3 ... the shower is performing poorly
In this situation it could be that the hand shower is scaled up or
contaminated. If so clean the hand shower or descale it. You can
order the hand shower from us as a replacement part with part
number 279482.
6.4 ... water is dripping from the tap
When water expands in the water heater expansion water drips
from the tap. This is a normal process.
