Adding rinse aid Adding rinse aid Rinse aid is necessary to ensure that water does not cling and leave marks on utensils during the drying phase. Rinse aid is poured into the storage reservoir and the amount set is dispensed automatically in the final rinse. The rinse aid reservoir holds approx. 125 ml. Adding rinse aid Inadvertently filling the rinse aid reservoir with powder detergent (or liquid detergent) always causes serious damage to the reservoir. Only use rinse aid formulated for this machine.
Adding rinse aid Add rinse aid only until the surface is visible in the opening. Close the flap firmly. The flap must audibly engage, otherwise water could get into the rinse aid reservoir during the programme. Mop up any spilt rinse aid. This prevents over-foaming occuring during the next programme. The flap should always remain closed. Only open it to add more rinse aid. Wait until the rinse aid indicator light H on the control panel lights up again before adding any more rinse aid.
Adding rinse aid Setting the dosage The dosage adjuster (see arrow) in the opening has settings adjustable from 1 to 6 (1-6 ml). It is set to “3” (3 ml) at the factory as the recommended dose. If there are flecks on utensils after drying use a higher setting. If clouding or smearing occurs on utensils after drying use a lower setting.
Adding cleaning agent Adding cleaning agent Only use cleaning agents formulated for specialist machines. Do not use detergents formulated for domestic dishwashers. Powder cleaning agent is dispensed via the dispenser for powder cleaning agents in the door or liquid cleaning agent via the DOS module (available as an optional extra - see “Note” on the next page).
Adding cleaning agent Note Dispensing system maintenance As a chargeable optional extra this machine can also be fitted with a “dispenser pump for liquid cleaning agent” (DOS module G 60). This is connected externally. See “Programming special functions” for information on venting the dispensing system and setting the dosage. To ensure safe functioning, maintenance work should be carried out at specified intervals.
