HEATER ELEMENT
The element comprises of front and rear pressings spaced apart with Mica type insulating material.
Through the insulating pieces are 4 runs of coiled resistance wire supported from end to end by
insulating material. High temperature insulated wires are crimped to the ends of the resistance strips to
complete the circuit.
Note: Heater assemblies manufactured by Blasi and DBK are interchangeable if replaced as an
assembly. Both types are used in production. The service replacement type is a DBK heater.
The thermostats are NOT interchangeable - DBK uses a 120°C, and Blasi uses a 106°C device.
The correct thermostat kit MUST ALWAYS be fitted - depending on the heater fitted.
The heaters can be identified by the appearance of the indentations in the rear cover - refer to the
photos below.
Blasi Heater Cover - with 2 pips
DBK Heater Cover - with 4 pips
SAFETY CUT-OUT (BLUE SPOT)
This device is a disc type thermostat set to operate at 150°C it is used as a safety device. It is positioned
above the element, to the right of the cycling thermostat on the element housing. If this device fails it
cannot be reset.
IF THIS DEVICE OPERATES, IT SHOULD ALWAYS BE REPLACED TOGETHER WITH THE
CYCLING THERMOSTAT (see next paragraph).
CYCLING THERMOSTAT
The cycling thermostat is mounted adjacent to the safety cut-out, is designed to open at 120°C (DBK)
or 106°C (Blasi). It limits the temperature of the heat entering the drum.
ECO THERMOSTATS
These are of self-resetting closed disc construction, mounted in the front air duct. They control the timer
motor on timer 1. When the load is dry, the selected thermostat operates and powers the timer motor;
this allows the timer to advance to cool run. The Full load thermostat (E) is designed to open at 55°C
and the half load (e) is designed to open at 60°C.
