OTHER FAILURES

Actions to perform
• The valve construction in the (yellow
tube) thermo heater became defect.
• Check if the holes of the spout are not
clogged.
• Check if the mobile drawer inside the
service door is blocked and cannot swing.
• The coffee is not running out of the
brewing unit spout but is leaking through
the brewing unit.
• Mostly the problem is caused by the fact
people use big not pre-heated mugs for
small amounts of Coffee.
• Increase the coffee temperature in the
menu.
• Measure the Coffee temperature see
instruction "Temperature measurement".
• The coffee is ground too coarsely.
Turn the grinding coarseness knob one
setting anticlockwise while the mill is
grinding coffee beans.

Turn the grinding coarseness knob
one setting clockwise while the mill is
grinding coffee beans.

Turn the grinding coarseness knob one

grinding the coffee beans.
• Change the coffee strength with the
coffee strength button.
• Clean the appliance with the 'cleaning'
function in the menu.

function in the menu.
If the water system has been frozen, most
probably the appliance is not able to make
Coffee any more.
The water cannot reach the Coffee powder
any more or water is leaking out of the
brewing unit.
The valve used in the brewing unit (yellow
tube) is mostly the part that has to be
replaced.
