Abstract (en)
[origin: EP1723889A1] Method and device (10) to indicate the need for reintegration of a regenerating substance of the anti-calcium function in a washer machine (16), which comprises a containing tank (17) for a regenerating substance, a discharge pan (20) and a command unit (26) suitable to activate, after a defined number of washing cycles, a regeneration cycle that uses the regenerating substance. The method provides the following steps: a meter in the command unit (26) is zeroed at the moment a performed reintegration of the regenerating substance is detected in the tank (17); the quantity of regenerating substance unloaded into the tank (17) is measured, by measuring the quantity of water that flows into the pan (20) following the reintegration; the number of regeneration cycles performed is progressively counted, starting from the last reintegration performed, and the quantity removed with every regeneration cycle is deducted from the measured quantity of regenerating substance introduced into the tank (17); and the need for reintegration is indicated after a number of regeneration cycles such that the regenerating substance remaining in the tank (17) has reached a preestablished minimum level.
