Cause
coffeepaddrawer won't open (vacuum).
Solution
you can solve the vacuum yourself by decompressing
the appliance using the valve behind the small hole on
the back of the appliance.
Procedure: make sure the water reservoir is placed
on the appliance. at the back of the appliance you
will find a small hole in the housing. Put a thin, blunt
object inside the hole and press to activate the valve.
Keep pressing it during several seconds until the water
stops flowing back into the waterreservoir and both
pilot lamps (red and green) light up constantly.
careful: the water that is being pumped back, is hot.
you have succesfully decompressed the appliance.
after you can open the coffee pad drawer again, you
must clean the crema maker and the multi padholder.
If you do not clean the parts, the cause of the vacuum
will not be solved and when reusing the appliance it
will get locked again.
Cleaning the crema maker: remove the crema maker
by pushing it out, from below, with a blunt object like
a pen or the back of a teaspoon and rinse it with warm
water. One grain of coffee can cause it to be blocked.
Cause
the lock does not work - the pilot lamp 6 keeps
blinking.
Solution
• make sure the coffeepad(s) has (have) been placed
correctly.
• coffee pad drawer is not locked, open the drawer
and lock it again.
• check the multi padholder - at the back there should
be a protrusion sticking out, when this has broken off
the machine is not able to make coffee. Order a new
multi padholder at your supplier.
