Indesit Company
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.
Cycling Thermostat ( 120°C +/- 3°C )
The cycling thermostat is mounted adjacent to the one-shot (safety) and is designed to open at 120°C. It
limits the temperature of the heat entering the drum.
Heater Unit ( for Condenser models = 2.3 kW )
Consists of 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 5 - way and a 2 - Way connector
provided to interface with the electronic module.
The heater has upper and lower heater sections.
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. See page 12 for Heater Technical information.
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.
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.
Operation of the Float Switch (water container full)
When the water container becomes full, the excess water is diverted back into the pump reservoir, which
causes the float to rise and the operation of the micro switch signals the module, the container is full.
After 2 minutes the machine will stop with the Start/Pause LED Flashing and the Empty Water LED
illuminated.
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.
Drum Earthing
Drum Earthing is obtained by the teardrop bearing fixing
screw.
NOTE: - It is important that the correct screw is always
used to secure the teardrop bearing.
