Blocked Filter
1. Static fill: the fill solenoid valve is piloted to open by the Main Module, and will admit
approximately 2.0 litres of water, measured by the Litre-count Turbine. When this threshold is
reached, the Wash Pump ("W-Sensor") runs at 1400 rpm with the bottom delivery outlet open,
to confirm whether or not the machine is in Full status.
If the Full condition is satisfied, the dynamic fill will start.
2. Dynamic fill: with the Wash Pump running (at 1400 rpm, bottom delivery outlet), the fill
solenoid valve is activated and held open by the main module until the water level increases to
around 3.5/3.8 litres.
At this point if a fault situation is confirmed, the machine continues to fill until:
> Full status is satisfied, in which case the wash proceeds as normal;
> It the Tub contains 5.5 litre's of water, or the dynamic fill timeout is exceeded; in both instances,
the program skips to the next step. (The programme will complete in a short period and the load
will be dirty at the end of the cycle.) No Fault code will display.
Detergent, Rinse Aid Dispenser and Oxygen Generator
Soap Dispenser / Oxygen Generator
The dispenser fitted to these models works
differently to dispensers previously found on
Hotpoint / Indesit Dishwashers.
Operation of Detergent Dispenser:
The dispenser incorporates a solenoid valve at
the rear which, when activated, opens the
dispenser to release the detergent and at the
same time releases the rinse aid.
The dispenser is activated:
1. The Solenoid is energised for one second, to release the detergent; the rinse aid will not be
released in this short space of time, because of its viscosity.
2. Once or repeatedly for a fixed duration of 10 seconds to release the rinse aid, depending on
the setting adopted by the user. Each time the dispenser is opened, 1.5 ml (1.5 cc) of rinse aid
will be released.
Possible settings:
0: Off (no rinse aid is released)
1. One pulse is generated, releasing 1.5 ml of rinse aid
2: Two pulses are generated, releasing 3 ml of rinse aid
3: Three pulses are generated, releasing 4.5 ml of rinse aid
4: Four pulses are generated, releasing 6 ml of rinse aid
