13. Drain
At the end of the drain phase, a control procedure is performed to check that the contact of the level
pressure switch is open on EMPTY. If this is the case, the appliance proceeds to the subsequent phase.
If, as a result of a problem in the drain phase, the pressure switch contact remains closed on FULL
(i.e. if there is water in the hydraulic circuit), the drain phase is repeated.
On completion of this second drain phase, the status of the pressure switch is again checked. If it is still
closed on FULL, alarm [i20] is generated (failure to drain). The time-out for each of these two phases is
120 seconds.
N.B. The washing programmes always begin with a drain phase.
11. Rinse out after regeneration
Recycling takes place after the rinsing
process, as the final step.
Rinsing out then follows automatically
with the start of the next wash program.
The pumping off stage usually takes
about 50 seconds.
12. Antisiphonic device
If the end of the take-off hose is below the level of
the water in the wash space, a siphon effect is
possible, that is, the machine runs empty. This is
avoided by the ventilation through the anti-siphon
valve.
