Figure 23 6.5 Cleaning / descaling the water boiler<br />
The water boiler 6 is a wearing part. To prolong its service life and for<br />
best possible appliance performance we recommend using lime-free/distilled<br />
water.<br />
The use of tap water may limit its life. Use a commercially available filter<br />
to treat hard tap water. Check the water boiler 6 for limescale deposits<br />
and descale at regular intervals depending on the degree of water hardness,<br />
as described below.<br />
ENGLISH<br />
The water boiler 6 contains small ceramic pieces 7. These ceramic<br />
pieces 7 considerably delay the development of limescale. They must<br />
therefore not be removed from the water boiler 6.<br />
1WARNING<br />
Danger of suffocation<br />
The ceramic pieces 7 could be swallowed or inhaled by children:<br />
• Do not remove the ceramic pieces 7 from the water boiler<br />
6.<br />
• Keep the water boiler 6 away from children.<br />
We recommend that the remaining water be emptied from the water boiler<br />
6 at the end of each working day and the water boiler 6 then be rinsed<br />
out with cold water.<br />
1. Comply with the safety instructions in “Section 6.1” page 70.<br />
2. Push the lock of the cover 5 forwards.<br />
➥ The cover 5 automatically opens upwards.<br />
3. Open / unlock the water boiler 6 with the handle 1 and lift it out of<br />
the compartment 2.<br />
NOTICE<br />
Damage to water boiler<br />
• Do not immerse the water boiler 6 in water or other<br />
liquids.<br />
• Do not put the water boiler 6 in the dishwasher.<br />
4. Clean the water boiler 6 outside with a moist (not wet) cloth.<br />
5. Clean the seal surfaces in the compartment 2 with a moist (not wet)<br />
cloth.<br />
1WARNING<br />
Caustic vapours<br />
• Do not descale the water boiler 6 in the appliance.<br />
Remove the water boiler from the appliance before descaling and then<br />
proceed as follows:<br />
6. Away from the appliance, fill the water boiler 6 with hot water, adding<br />
a commercial descaling product:<br />
• Follow the manufacturer's instructions for the descaling product.<br />
• Leave the descaling solution to work for several hours.<br />
• Repeat procedure if necessary.<br />
