Fisher & Paykel notes

                                FISHER & PAYKEL WASHER

This washer has no tranny. The motor resembles an old propeller motor in a P52 Mustang.

The rotor is attached directly to the agitator. The stator is bolted to the base of the tub. It has an electric pump simular to ge and frigidaire electric washer pumps. In order to wash, the basket is floated upwards. The onboard computer senses the basket is a floating and commences agitation. The exact position of the basket is always checked by the motor control module and pickup. The main computer is water cooled! I kid you not. water is diverted around the computer module to keep it cool. And if it over heats it waters itself down to cool off.

This module contains the circuits

needed to control the water valves,

pump, water level and rotation of

the motor.

The Pressure Sensor, used to

detect the water level, is part of

the Motor Controller Module and

cannot be removed.

The motor is a 3-phase DC

brushless motor. The Motor

Controller Module controls rotation

of the motor. Fitted to the Stator

(stationary part) is the Rotor

Position Sensor. This detects the

position of the Rotor (moving part)

and feeds a signal back to the

Motor Controller Module.

FLOATING BASKET

During spin, the agitator and the

basket have to be coupled together

and turn as a single unit. In

agitate the agitator and basket has

to be free to rotate independently.

At the base of the basket is a

flotation chamber. As the water

level rises the basket will float.

This action disconnects a clutch

between the agitator and basket.

The agitator and basket can now

move independently.

When the water is pumped out,

the basket sinks down and reengages,

allowing the agitator and

basket to turn as one unit.

PUMP

The drain pump motor is attached

to the base of the tub. The pump

housing is an integral part of the

tub. The pump can be accessed

from the top, if the agitator and

basket are removed, or from

underneath the machine.

Note. If the pump is open circuit

or the wiring is disconnected the

machine will not function.

A diverter valve is located

underneath the tub. This directs

the tub water to the drain hose or

to the re-circulation hose. The

valve is on whilst the machine is

filling and re-circulating the wash

water. It is also turned on briefly

at the beginning of the rinse cycle

to allow the re-circulation hose to

empty.

MOTOR CONTROLLER MODULE

This module contains the circuits

needed to control the water valves,

pump, water level and rotation of

the motor.

The Pressure Sensor, used to

detect the water level, is part of

the Motor Controller Module and

cannot be removed.

DISPLAY MODULE

This receives the inputs from the

front panel (i.e. User settings) and

sends the appropriate command to

the Motor Controller Module.

Facinating ain't it?
