9.6.17. FUNCTIONAL DESCRIPTION OF THE SELF-CLEANING
Each output interprets a sequence, which is shown on the diagram in the picture below.
During the self-cleaning programme, the level control is not performed in either the tank or the boiler. Similarly, the
tank and boiler resistors remain cancelled.

9.6.18. REGENERATION PROGRAMME
Programme for models: AD-125 SOFT, AD-125 SOFT HRS
There are two types of regeneration:
1. Short regeneration: When the stipulated cycles have been run, the control performs a short regeneration.
The number of cycles depends on the degree of water hardness that has been defined.
In this type of regeneration, the display does not show any different messages, i.e., if it is in wash cycle, the
messages corresponding to the wash cycles are displayed.
The short regeneration will begin as soon as the currently running wash cycle has ended (if the stipulated
number of cycles has been finished) and the boiler has been filled. If the user runs another cleaning
programme, the regeneration stops, but the rinse process will not be able to start until the regeneration
process has ended.
2. Long regeneration: Every 4 cycles of short regeneration, a long regeneration takes place. The long
regeneration takes place 15 minutes after the machine is switched off. If the machine is not switched off, it
continues running short regenerations as required, but a long regeneration will not take place until the
machine has been switched off and 15 minutes have elapsed.
The display shows the message “REGENERATION” during the operation.
9.6.19. FUNCTIONAL DESCRIPTION REGENERATION PROGRAMME
The sequences to be followed for the short regeneration (3 minutes) and the long regeneration (13 minutes) are
described below.
If the power supply is disconnected during any of the regeneration cycles, or the machine is switched off, when the
machine is switched on again, it should automatically start the short regeneration cycle (otherwise salt water will
enter the tank), displaying the message “REGENERATION” on the screen.
