2.5 Water

Valves

The Phase 7 machines use a new dual valve
block assembly. Independent coils control the
hot and cold water supply, which feeds the
water through a common outlet.

The valve block has a location feature for the
thermistor.

2.6

Water Level Measurement

The machine is fitted with a pressure sensor, which can control the fill to any water level. The
pressure sensor is incorporated within the Motor Control Module and cannot be removed. The
pressure tube connects from the Motor Control Module to the air bell at the bottom of the outer
basket, and is part of the harness assembly. Care must be taken when removing or refitting the
pressure tube to the pressure sensor as too much force can damage this device.
