Water Valve-Open

The armature spring is compressed by this action.

When the armature moves up, it allows the water on the

top of the diaphragm to drain through the main orifice.

The diaphragm bleed orifice is much smaller than the

main orifice and will not admit enough water to maintain

pressure on the top side of the diaphragm. Thus, as the

pressure on the top of the diaphragm is reduced to

almost zero, the pressure on the bottom lifts the

diaphragm off the valve seat, allowing a full flow of

water.

Figure

Water Valve- Diaphragm Up

When the solenoid is de-energized, the armature drops

down, closing the diaphragm main orifice. Water contin-

ues to flow through the diaphragm bleed orifice,

equalizing  the pressure and allowing the spring to push

the diaphragm down against the valve seat.

Water Valve-Closing

To Test Water Valve:

1. Disconnect the washer from electrical supply.

2. Make a continuity check of the valve harness to

determine whether or not a circuit exists.

3. Use an ohmmeter. Resistance of the solenoid

should be approximately 880 ohms ±10% @ 77°F.

4. If harness and solenoid test OK, simulate a normal

valve operation by testing solenoid coil, using a

separate 115 volt power source directly, with a

properly fused and grounded service cord.

5. If water valve operates on both solenoids, check

timer, water level control, and water temperature

selector switch circuits. If water valve fails to

operate, check valve inlet screens for debris and/

or replace water valve.

To Remove or Replace Water Valve:

The water valve is mounted on the cabinet at the left

rear of the washer. The valve may be replaced by

removing either the top or rear service panel.

1. Disconnect washer from electrical supply and turn

off the water supply.

2. Remove hot and cold fill hoses from water valve.

3. Remove top or rear service panel.

4. Remove two screws securing water valve to cabi-

net brace.

5. Remove the wiring harness connector plugs.

6. Remove clamp securing water valve to air gap

hose.

7. Reverse procedure to install the new water valve.

Check for operation.
