Ducts
• Dirt and lime deposits in the ejection
mechanism may cause bad ejecting function
or none at all.
Clean all ducts with a soft iron wire or the like.
Remove deposits on other surfaces with steel
wool.
Rechecking water flow:
When the solenoid valve for make-up water is
open, there should be weak water jets.
At operation the make-up water consumption is
zero when the water pressure is less than 50 kPa
(0,5 bar).
At discharge the water jets should be
strong
(1,5 - 3 litres / discharge).
Finally, when the machine is completely
assembled, make a test run to make sure that the
discharge function is in order.
Assembly
Assembly takes place by reversing the sequence
of operations for dismantling. Observe the
following:
The distributing cover is angularly positioned by a
guide pin.
If it is difficult to press down the control paring
disc in position by hand, knock it down cautiously
by means of a plastic hammer.
Check that the uppermost O-ring (locking the
paring disc) lies properly in its groove without
being twisted.
In order to ensure a good sealing between the
paring disc and the 0-rings, jerk a few times in
the distributing ring after assembly.
