2.2
Safeguards
The appliance is fitted with the following safeguards:
2.2.1
Dry-boil protection (14)
This application is equipped with two dry-boil protection on the back. The protector on
the left (21) is that of the water boiler. On the right (20) is the one of the coffee making
section.
These protectors trigger if the heating element overheats owing to a fault. Once the fault
has been resolved, the dry-boil protection can be reset at the back of the appliance. The
most common cause of the dry-boil protection being triggered is not descaling the heating
system in time.
If the heating system does not switch back on, proceed as follows:
•
•
•
Allow the appliance to cool down.
Unscrew the protective cap, which can be found on the back of the appliance.
Press the button which is now visible and firmly screw the protective cap back on.
If the dry-boil protection triggers owing to increased scale deposits, descale the appliance.
Consult your dealer if the fault was caused by a problem other than the dry-boil protection
being triggered.
2.2.2
On/off switch (1+13)
Each appliance is switched on/off separately through the on/off switch (1+13). Remember
that the appliance can still be live after switching it off! For this reason you should always
remove the plug from the socket to render the appliance voltage-free.

Observe the descaling intervals indicated by the descale indicator light. Overdue maintenance to the heating system can result in high repair costs and annulment of the guarantee.
It is recommended to descale the coffee making section and the water boiler in succession.
Scale deposits are left in the heating system when the appliance is used. The amount of
scaling depends on the hardness of the water being used. The appliance is fitted with a
descale indicator light (5.2), which lights up when the heating system has processed a certain quantity of water and has to be descaled. The appliance continues to work so that it
can be descaled when it is not being used.

Before descaling the water boiler, carefully read the instructions for use on the descaling agent.
Switch the water boiler off when the temperature ok indicator light (12.2) is on.
Leave the water boiler switched off during the whole descaling process.
Draw off approx. 1.5 litres of hot water using the no-drip tap (11) and dissolve 2
sachets of 50 grams of descaling agent in it.
Pour the solution into the water boiler. This will start a (fizzy) reaction on the scale
deposits.
Leave this solution during 10 minutes to soak in.
Regularly spread the solution over the scaled parts in the hot water boiler using a
brush. Draw off some solution and pour it back immediately.
The entire water boiler can be emptied by using the water drain (22) on the back
of the appliance.
Make sure that the end of the tap hose is in the sink.
Pull the tap plug together with approx. 20 cm hose out of its compartment. Remove
the plug by squeezing the hose just before the seal plug. Warning: The water is still
hot.
Draw the water boiler completely empty and rinse well using clean warm water.
Rinse away all the solution.
Close the tap hose and push it back into its compartment.
Switch the water boiler on/off (13). The water boiler will fill up again.
If there is still scale in the water boiler, repeat steps 3 to 9.
Before use, rinse the no-drip tap once more by drawing off approx. 1 litre of hot
water.
The water boiler is now ready for use.
