Inlet valve
The inlet valve has an electrical connector
that is coded to ensure it is not mixed up. It is
fi tted with a fi lter, which can be removed for
cleaning. Both single and safety valves are used
as inlet valves. The inlet valve contains a fi lter
to stop particles then a fl ow limiter to limit
the fl ow to a maximum of 4 L (1 gallon)/min.
It opens when the water pressure exceeds 0.3
bar (4.3 psi) and provides full fl ow at about 2
bar (29 psi). It has a pressure range of 0.3 bar
(4.3 psi) to 10 bar (145 psi). The inlet valve is
fi tted to the air gap and can be replaced from
the rear of the machine.
Purpose: To ensure that the machine
is supplied with water for the different
dishwashing cycles.
Safety valve
The safety valve has two independent valve seats,
each controlled by a separate electromagnet.
The valve seats are connected in series. This
doubles the safety factor. The electromagnets
are also connected in series (electrically), which
means each magnet’s rated voltage is half the
line voltage (e.g., a 230 V valve = 2 x 115 V coils)
Single valve
The single valve comprises an electromagnet
and a valve seat.
Components and function description
Here we describe the function and
specifi cation of the most important
components. Certain components are found
only in more highly specifi ed machines or in
particular markets. See the
Troubleshooting
section for fault and information codes.
CU, Control Unit
The CU, or Control Unit, is a unit that functions
as both a control panel and a logic component.
The control panel is fi tted with a display and touch
buttons for selecting programs, options and Start/
Stop. The control panel is an integrated part of
the CU and cannot be replaced separately. The
logic component manages functions needed for
dishwashing programs and diagnosis. The CU
has an internal power supply for the logic. In the
event of a fault, the CU can diagnose a number of
components and functions and display fault codes.
To facilitate troubleshooting the service menu
includes a component diagnostics function, which
activates the outputs in a particular sequence.
Accelerometer
The control unit contains an accelerometer, a
sensor that senses position and acceleration. It
controls the touch buttons and the brightness
of the light. The accelerometer turns off at a
specifi c angle to avoid causing a distraction
when seen from the worktop. It is calibrated
when the door is closed.
If this symbol appears on the display
the door is not open enough. Open
the door until the display lights up.
