6. Pour the acid solution into the reservoir ( g. 8-1).
The acid solution will now react with the lime scale.
7. Leave the solution to soak for a minimum of 10
minutes, until the foaming has stopped.
8. Use a brush to spread the acid over the level
electrodes during the soaking time ( g. 8-2).
9. Put the plug in the socket again and turn on the
device so that the reservoir warms up.
10. Activate the MIXER cleaning programme ( g. 8-3),
so that the acid solution leaves the water reservoir
via the MIXER VALVES. Place a drip tray under
both outlets ( g. 8-4) and follow the instructions on
the
display.
11. Turn off the device and allow the reservoir to empty
completely using the tap ( g. 8-5).
12. Turn on the device again; the reservoir will re ll with
clean water. Repeat instruction 10 one more time to
rinse the reservoir completely free of acid.
13. Turn on the device again; the reservoir will re ll with
clean water. Allow the water reservoir to heat up.
14. Activate the MIXER programme ( g. 8-3) three
times (3x), so the valves and pipe systems are
rinsed clean. Place the measuring jug under the
outlet ( g. 8-4).
15. Repeat the above descaling procedure if lime scale
is still present in the reservoir.
16. Screw the lid back onto the reservoir and replace
the rear plate.
17. Clear the service parameter counter in the Service
Menu
2.6 Descale / lter /2.6.2 Reset service
counter.
18. The device is now ready for use again.
