How to set water-hardnes on 4 Led dishwashers:
First check to see that the dishwahser is not on and the door is open.
1.
Switch on the dishwasher on “Power On”.
2.
Soon after, press button “P” and keep pressed for about 6 seconds. As many leds as hardnss of water that has been set,
will come on(eg. A flashing led indicating water-hardness relating to one; for water-hardness set on two: one led will stay on and
the second will flash, water-hardness set on three: first two led will stay on and the third will flash etc.)
3.
By working on button “P”, the water-hardness may be modified: 1-2-3-4-5; and by keeping it pressed it will go back
repeating 1-2-3-4-5-1-2-3-...etc.
4.
Once the selection has been set, a further 10 seconds must be waited till the machine takes up the reading automatically
on the alternative that has been set or when the dishwasher has been switched off.
NB: Whereas on previous models, regenerating of resines is not done at the end of each washing-cycle, but only in
accordance to the water-hardness setting and the quantity of water charged into the dishwasher and only on
programmes where it has been envisaged (hence soaking-cycle). Should the quantity of water charged into the
dishwasher exceed the quantity prescribed by Editor (consult Table attached) the dishwasher, will, at the end of its
washing-cycle proceed to regenerate the resins.
THE “REGENERATING” PROCESS
1.
Fill up a certain quantity of water (about 90cc), which will activate the process and fill up electro-valve which will send the
water onto the salt. Consequently the salt-water will be sent onto the resines, and the electro-valves will then close.
2.
Wait for about 10 minutes.
3.
Fill up a second quantity of water into the machine (about 190cc) following the same procedures.
4.
Wait a further 5 minutes.
5.
Proceed to rinse the resines, allowing one to two litres water to flow over the resines by activating only the fillin-up
solenoid-valve and not the “regenerating” one.
6.
Finally discharge the water.
NB: Whenever the main-board is replaced, the litre-count important in the administering of water-hardness and
sparkling rinse-agent, will be lost and hence the dishwasher must be set again. It may be found that the quality of the
sweetener in some cycles has not quite reached optimum level.
Drying Cycle:
The drying-cycle is based on the same principle used on models EVO3. In the last stage the dishwasher will rinse up using hot
water obtained by activating the heating-element. The water will reach high temperatures, depending on the programme that has
been selected: eg it may reach 70°C on certain programmes or it may not even exceed 64°C as on “Baby Cycle”!
Following this, the plates will be allowed to drip-dry, with water still in the basins, waiting for the water-vapour on the sides to
condensate. The sparkling-rinse agent, introduced by the User has an important function in the drying-cycle, in allowing the
water-drops to drip away from the dishes.
The drying-cycle does also envisage a certain time-lapse without water in the basins.
NB: Optimum results may be obtained when using washing-powder soap and a liquid sparkling-rinse agent.
Blocked Filters:
Should the filters be blocked, or should the User introduce a pot having the opening facing upwards, the Pressostat could
indicate “empty” status. In this circumstance, the models EVO3 and LVS would move onto Filter-cleaning stage- However this
procedure is not available on this model, consequently, the machine will either continue filling up water till the pressostat has
reached full status or it will proceed to fill up to 5.5 litres. In the latter case, i.e. 5.5 litres, the LVS will discharge the water and
proceed onto the next washing-cycle. Should “blocked filters” still persist, the user could call up saying that the dishes were still
dirty at the end of the washing-cycle.
The Call-Center must be advised to recommend:
1.
Washing the filters
2.
Placing pots and pans facing downwards and starting the wash-cycle again.
