Never use vinegar, as this would cause damage to themachine!Warning. If the “Aqua prima” filter is installed, remove it from thewater tank before pouring in the descaling solution.Descaling serves to remove limescale deposits from surfaces and openings inthe water circuit, thereby keeping the valves, heating controls and other impor-tant elements in perfect working order.Important. Given the complexity of the machine water circuit, thedescaling procedure described below is not able to reach all com-ponents.In fact, components such as the brew unit and the plastic pin/valve con-necting it are excluded from the cycle.The descaling procedure must be carried out regularly, every 3 – 4 months.If the water used is particularly hard, it should be performed more frequently,preferably using the “Aqua prima” filter, which can be purchased separately.This machine is equipped with a special counter which, when enabled, signalsthe urgent need to perform descaling, according to water hardness.In such a case the display will show this message.¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼Saeco Office OneReadyPlease descaleWhen this message appears the machine does not stop, but it is advisable toperform the descaling procedure as soon as possible.Go to the service menu as directed in section 11.1 and display the descalingmenu.¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼2.4.DescalingUsing the appropriate controls, select “Do it now” to launch the descaling cy-cle.¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼2.4.3.Do it nowNote: it is recommended to interrupt the descaling cycle.The descaling solution is dispensed into the dreg drawer.The display will show:¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼Descalingin progressEmptydreg drawerEmpty the dreg drawer of the used capsules and liquids.During the emptying operation, the display will show:¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼Descalingin progressEmpty dregdrawerWait please...It is possible to insert the dreg drawer in the machine only when the displayshows:¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼¼Descalingin progressInsertdreg drawerThe machine heats the boiler to the correct temperature for carrying out thedescaling cycle properly.
