Group valves
Figure M 20. The left hand side group solenoid valve seen from aside (left) and above (right) showing
the steps to remove a 3-way valve. Start with plug (1), then hose clamp (2), then loosen the tubes on
both sides (3), then remove the copper tubing (4), remove from frame (5) and finally pull from hose (6).
1. Remove electrical plug from coil.
2. Remove flat nut retaining coil to valve with spanner 14 mm, remove coil.
3. Loosen hose clamp on bottom side (discharge) of group valve with 7 mm socket wrench or Phillips
screw driver, slide the clamp down over the hose. The hose clamp on the middle group valve of a
Triplette is difficult to access, it may be useful to completely loosen the valve first such that you
can twist it a little.
4. Loosen 16 mm nuts on both sides of the valve, retain the fittings with a 14 mm spanner (see
5. To get extra space, remove the copper tube that leads water from the upper group duct to the
valve completely, again retain the fitting with a spanner.
6. Remove the two bolts (7 mm) that hold the valve to the frame (Phillips no. 2 for middle group valve
on Triplette).
7. Pull the valve from the drain hose.
Note!
Try to keep the drain hoses attached to the drain pipe. These hoses are difficult to remount once the
machine is assembled.
8. Remove fittings from old valves.
9. Clean fittings, check particle screen and restrictor (normally 0.6 mm, some machines are ordered
with 1.0 mm group valve restrictors), clean or replace when necessary.
10. Mount fittings on replacement valves with drop of Loctite, use new copper O-rings.
Caution!
The entrance to the valve is indicated by a little arrow pointing inwards, the fitting with particle screen
and flow restrictor must be on this side.
