Inlet valve for W185
up to S/N 9508/011934
The water inlets have brass bodies with larger
cross section of the outlet in order to achieve a
shorter filling time for the machine.
Construction
The valve housing is made of pressed brass. The
spring-loaded plunger is made of stain-less steel
and located at its lower end is a rubber gasket for
the pilot valve.
Operation
The valve is automatically operated by means of
a rubber diaphragm and a pilot valve in exactly
the same way as the supply injector valve.
NOTE: To strip, clean, re-assemble and
troubleshoot the inlet valve, follow the
instructions outlined for the supply
injector valve.
Clean out
At water temperatures of more than 60°C/140°F,
the lime deposits are heavily increased. This can
cause function problems due to blocking up the
equalizing orifice of the valve.
The fault can be eliminated by cleaning the
equalizing orifice (marked A).
If there are much deposits the orifice can be
changed from 0.5 mm to 0.8 mm. The screwhead
of the orifice is marked with 1 ring for the size of
0.5 mm and 2 rings for the size of 0.8 mm.
Clean the orifice as follows:
1. Shut off the main supply.
2. Unscrew the orifice.
3. Clean the hole in the orifice carefully with a
pin or similar not thicker than 0.5 resp.
0.8 mm.
4. Mount the orifice, be careful with sealing and
tighten.
5. Open the main supply.
