Cleaning and care Cleaning the wash cabinet, tank and filters ,The dishwasher must not be used without all the filters in place. The tank and the filter combination should be inspected regularly and cleaned if necessary. How often they need to be cleaned will depend on the degree of soiling and the number of times the dishwasher is used. However, they should be cleaned at the end of every operating session.
Cleaning and care Cleaning the flat filters ,The water in the tank can be hot. The tank must be drained before removing the filters. Cleaning the fine filter ,The water in the tank can be hot. The tank must be drained before removing the filters. ^ Remove the flat filters. ^ First remove the flat filter at the front. To do this lift it up a little at the front. ^ Then remove the flat filter at the rear. To do this lift it up a little at the back. ^ Clean the filters thoroughly under running water.
Cleaning and care E-Cloth Cleaning the spray arms ^ A microfibre "E-Cloth" is available from the Miele UK Spare Parts Department, which is suitable for cleaning surfaces such as stainless steel, glass, plastic and chrome without the use of chemicals. Waste particles can lodge in the spray arm jets. It is therefore important to inspect the spray arms regularly (at least every six months).
Problem solving guide With the aid of the following guide, minor problems can be easily corrected without calling in a Miele service technician, saving you both time and money. The following guide may help you to find the reason for a fault, and to correct it. You should, however, note the following: ,Repairs should only be carried out by a suitably qualified and trained person in accordance with local and national safety regulations.
Problem solving guide Problem The wash cycle finishes early and the 6 indicator light flashes (fault code F..A appears in the display). Knocking noise in the wash cabinet. Rattling noise. Possible cause The filters in the wash cabinet are clogged. The drain pump or non-return valve may be blocked. Clean the filters, see "Cleaning and Care". Clean the drain pump and the non-return valve, see "Cleaning the drain pump and non-return valve". The drain hose is kinked. Remove any kink in the drain hose.
Problem solving guide Problem Possible cause Remedy The dishes are not clean. The dishes were not loaded correctly. Dishes were placed inside other pieces, water could not access all surfaces. The programme was not powerful enough. See "Loading the machine". The spray arm jets are blocked. Clean the spray arms, see "Cleaning and Care". The filters in the base of the wash cabinet are not clean or are not correctly fitted. This may cause the spray arm jets to get blocked.
Problem solving guide Problem Possible cause White residue is visible Not enough rinsing agent on cutlery and crockery, was used. clouding occurs on glassware; film can be wiped off. There is no salt in the salt reservoir. The salt reservoir cap has not been screwed on correctly. The rinsing agent dosage Smearing appears on glassware and cutlery, is set too high. there is a bluish sheen on the surface of glassware; film can be wiped off.
