Water Valves - Fisher & Paykel GWL03US Service Manual

5.1.7 WATER VALVES

The washer is fitted with an automatic water temperature fill system. The electronics control the
water valves so that a constant water temperature is achieved in the tub irrespective of the
temperatures and pressures of the household hot and cold water systems. This system will also
compensate for changes in pressure and temperature during the washer's fill cycle.
To achieve this the cold valve is a special type of valve called a proportional water valve. Unlike
conventional water valves which are either fully on or fully off, the proportional water valve can be
controlled so that it can turn on at any water flow rate between fully on and fully off. The hot water
is controlled by using a conventional type of water valve.
It is important that the correct water valve is fitted should they ever need replacement. The valves
can be identified by the following features:
Proportional Valve
Filter colour – White
Shape of water valve plunger.
Has no stand offs
Difference between Proportional and Standard Valve
