When the motor is activated and begins to rotate, the piston rod is turned
upwards via the gear, the diaphragm is pressed upwards with the piston
and presses against the valve seat: the valve closes.
The connection for overfilling is connected to the upper part of the wash
drum, water and foam are diverted straight to the drain if the intake valves
or level control should malfunction.
On the riser for the wash drum are the connection for water filling and a
nipple for connecting the sensor line for the level control.
Instructions for repair
Deposits on the diaphragm can prevent the valve from opening or closing
properly. The valve should therefore be cleaned at certain intervals,
depending on operating conditions and water quality.
If the valve is not opening or closing properly:
• Check that the motor has the right input voltage.
• Check that the piston rod can move freely.
• Check whether the diaphragm is clogged with deposits.
To note if replacing the motor:
Brown cable: 60 Hz
