6. Pour the acid solution into the reservoir (fig. 14-1).
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 (fig. 14-2).
9. Put the plug in the socket again and turn on the
device so that the reservoir warms up.
10. Activate the BREWER cleaning programme
(fig. 14-3), so that the acid solution leaves the water
reservoir via the BREWER VALVES. Place a
drip tray under both outlets (fig. 14-4) and follow the
instructions on the display.
11. Activate the MIXER cleaning programme (fig. 14-5),
so that the acid solution leaves the water reservoir
via the MIXER VALVES. Place a drip tray under
both outlets (fig. 14-4) and follow the instructions on
the display.
12. Turn off the device and allow the reservoir to empty
completely using the tap (fig. 14-1).
13. Turn on the device again; the reservoir will refill with
clean water. Repeat instruction 10 one more time to
rinse the reservoir completely free of acid.
14. Turn on the device again; the reservoir will refill with
clean water. Allow the water reservoir to heat up.
15. Activate the BREWER cleaning programme
(fig. 14-3), so that valves and pipe systems are
rinsed clean. Place a drip tray under both outlets
(fig. 14-4).
16. Activate the MIXER programme (fig. 14-5), so that
valves and pipe systems are rinsed clean. Place the
measuring jug under the outlet (fig. 14-6).
17. Repeat the above descaling procedure if lime scale
is still present in the reservoir.
18. Screw the lid back onto the reservoir and replace
the rear plate.
19. Clear the service parameter counter in the Service
Menu 2.6 Descale / filter /2.6.2 Reset service
counter.
