One-Shot (Safety) Thermostat (White Spot)
This device is a disc type thermostat set to operate
at 143°C. It is used as a safety device.
It is positioned above the element. If this device fails
it cannot be reset.
Note:
The one-shot (safety) thermostat is wired
in the control module Neutral circuit.
If the one-shot fails open-circuit, the dryer will be
DEAD. No fault code will display.
Cycling Thermostat
The cycling thermostat is mounted adjacent to the one-shot (safety) and is designed to open at
106°C. It limits the temperature of the heat entering the drum.
Heater Unit
Consists of four coils wound on mica supports, which are supported by mica end insulators. These end
insulators fit into a steel pressing that also locates the rear thermal controls. This is fixed by screws to the
rear cover. This pressing also forms air guides. The heater elements, thermal controls, thermistors and
rear cover are supplied as an assembly and has a five-way connector provided to interface with the
electronic module. The heater has an upper and lower heater. The lower (static) heater is permanently
energised and the upper heater (dynamic) is cycled on and off by the control module during a programme
to maintain the correct temperature for the programme selected.
Pump & Float Switch
Mounted on the bottom right hand side of the rear panel, condensate water from the condenser
chamber is pumped via an external hose to the water container situated behind the console.
The pump runs continually throughout the programme.
Motor
A two pole P.S.C running at 2800 rpm with the impeller fitted to the rear end of the shaft and the drive
belt running directly in grooves in the front end of the shaft. It is protected from overload by a
self-resetting internal cut-out that interrupts the electrical supply to the windings.
It is used together with a capacitor that is mounted on the base of the dryer.
Drum Rear Seal
This unit comprises of a ring of foam with a webbing bearing face. Lubrication is applied to the drum
where the webbing surface runs, to reduce noise and wear. The seal reduces air losses at the rear
of the drum. The joints in the foam are sealed with glue and the joints in the webbing are stitched to
further reduce air leakage.
Operation of the Float Switch:
After continuing to tumble and dry for a further
one minute, the dryer will turn off the heater and
cool tumble for a further
10 minutes - before displaying the Fault Code
H20, with the Start/Pause button flashing orange
and the Empty Water light flashing.
