Cleaning, care and maintenance
4. Cleaning, care and maintenance
- Have the function of the safety assembly and electrical safe-
ty of the fitted accessories regularly checked by a qualified
contractor.
- We recommend having the protective anode initially checked
by a qualified contractor after 2 years. The qualified contrac-
tor will then determine the intervals at which repeat checks
should be performed.
- Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
4.1 Scaling
Almost every type of water will deposit limescale at high tem-
peratures. This settles inside the appliance and affects both per-
formance and service life. If a threaded immersion heater is in-
stalled, the heating elements must be descaled from time to time.
A qualified contractor who knows the local water quality will tell
you when the next service is due.
f Check the taps regularly. Limescale deposits at the tap out-
lets can be removed using commercially available descaling
agents.
5. Troubleshooting
Problem Cause
The flow rate is low. The aerator in the tap
or the shower head is
scaled up or dirty.
If you cannot remedy the fault, contact your qualified contractor.
To facilitate and speed up your enquiry, please provide the serial
number from the type plate (000000-0000-000000).
