6. MAINTENANCE
■ Clean the machine with a clean damp cloth.
■ Avoid using abrasive. It can cause scratches and dim spots.
■ Remove scale deposits by using scale remover.
6.1 Descaling
During operation scale will develop in the machine. Therefore the machine needs to be descaled
approx. once a month to guarantee the lowest energy consumption and proper functioning.
When to descale?
■ Depending on the frequency of use and hardness of water used, we advise to inspect the
unit regularly for scale formation.
■ Remove the cover of the storage water heater regularly. If there is loose scale on the bottom
or if there is severe scale formation on the walls, then the unit needs to be descaled.
■ In some cases it is sufficient to only remove the loose scale.
1. Switch off the machine and remove the plug from the wall socket.
2. Remove the cover from the storage water heater.
3. Turn the machine upside down over the sink. The loose scale will come out.
4. If there isn’t any scale in the machine anymore, it taken into use again.
Consult section 5 “Preparation before use”.
To remove remaining scale use Animo scale remover.
5. Carefully read the caution notice and the directions on the sachet Animo scale remover.
6. Dissolve 1 sachets of 50 gram Animo scale remover into 2 litres of warm water.
7. Fill the hot water reservoir with the solution. This will now undergo a reaction with the scale
deposits.
8. Allow the solution to soak in for about 10 minutes until the frothing has stopped.
9. Tap some of the acid off and pour it back into the reservoir.
10. Turn the machine upside down above the sink. Rinse the reservoir and the hot water tap, clean
with hot water.
11. If there is no scale left in the machine anymore, it taken into use again. Consult section
5 “FIRST TIME USE & USE”.
