Inlet System / Overfilling/Leakage Protection (Old Version) - Electrolux Compact Service Manual

Inlet system - old version
A The inlet hose is a rubber hose with plastic cover.
The coupling nuts are made of plastic (which reduces
the risk of crossedhreads) . The inlet hose is inside the
washing chamber when the machine is delivered, and the
consumer must fit the hose when installing the machine.
He must then also decide whether the hose is to run to the
right or to the left.
B On the machine, the inlet hose is connected to the
inlet valve (also known as solenoid valve). When the
inlet valve is energized (via the programmer) the valve will
open and water will flow into the machine. When the level
controller has sensed that the water has reached the
correct level, it will open the power supply circuit to the inlet
valvet and the valve will close.
The valve is designed to open and close slowly. It is
important to ensure that no harmful pressure surges will be
caused in the water supply mains.
D Flooding. If a component or seal should start to leak,
the water will collect on the base plate and will
activate the floating body. To some extent, the wall along
which the water flows serves as a brake,so that spillage of
a few drops will not cause the moisture sensor to trip.
C Overfilling protection. If the level sensor should fail to
operate and the inlet valve should remain open after
the water has reached the correct level, the water will run
across an overflow baffle down into the base plate, where
the floating body of the flooding protection system will
close the inlet valve and will prevent water damage.
Overfilling/leakage protection - old version
E The inlet valve also incorporates a mechanical tripping
actuator. The tripping actuator is operated by a floating
body .
If water should leak into the base plate for reason,
the floating body will close the inlet valve mechanically.
The leakage protection will operate even if the
power supply cable is disconnected.
Reverse flow protection.
F This prevents contaminated water from the dishwasher
from being drawn back into the water mains, even if a
vacuum should occur in the water mains.
