8.4. Heater
It is used to heat the water inside the drum.
Since it is an electronically controlled machine, there is a double thermocouple at
each of the heater inlets.
When the heater operates dry, the overheated thermocouple open circuits the heater.
Open circuited heater cannot be used again. In order to prevent the heater to
operate without water “during heating”, heater safety water level is defined to the
microprocessor (Psafety). When the water level which is measured by the water level
sensor comes under the defined Psafety level, heater is disabled.
When the water temperature which is read by NTC reaches to the “selected
temperature”, heater is disabled by the microprocessor.

8.5. Valve
There is 2-way valve in the models which have a single water inlet and there is 2-way
valve and extra single valve in the hot-water inlet machines. Valves are driven by the
triacs on the electronic board; and they are driven with both valves in the softener
step by use of crashed water directing system and the water is directed to the
medium compartment of the detergent dispenser.
Rated Voltage
220-240 V 50/60 Hz
Rated Power 5-8 W
Winding Resistance 3400-4500 ohm
Flow 10 l/min
8.6. Drain Pump
It is a synchronous motor equipped with a mono-phase bipolar magnet rotor. At the
draining step, electronic control card is activated by the triac on it. It is protected by
impedance for continuous operation and blocking situation of the rotor.
Drain pump drains the water inside the drum.
