Adding rinsing agent Rinsing agent is necessary to ensure water does not cling and leave marks on items during the drying phase and to help items dry faster after they have been washed. Rinsing agent is poured into the storage reservoir and the amount set is dispensed automatically in the final rinse. The rinsing agent reservoir holds approx. 125 ml. Except: Rinsing agent is not dispensed in the final rinse in the BEER GLASS programme. The final rinse in this programme is carried out with cold water only.
Adding rinsing agent ^ Add rinsing agent only until it is visible on the surface of the filter in the opening. ^ Close the flap firmly. The flap must audibly engage, otherwise water could get into the rinsing agent reservoir during the programme. ^ Mop up any spilt rinsing agent. This prevents over-foaming occuring during the next programme. The flap should always remain closed. Only open it to add more rinsing agent.
Adding rinsing agent Setting the dosage The dosage adjuster in the opening has settings from 1 to 6 (1-6 ml). It is set to 3 (3 ml) at the factory as the recommended dosage for rinsing agent. ^ Use a higher setting if there are marks on the surface of utensils after drying. ^ Use a lower setting if the surface becomes cloudy and smeary.
Adding cleaning agent ,Only use cleaning agents suitable 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 Programme J SUPER SHORT: Maintenance of the dispensing system To ensure trouble-free operation, regular maintenance should be carried out at specified intervals by a Miele approved service technician. Every 12-18 months Replace the dispensing hoses in the DOS modules. ,Take great care when handling ^ If liquid cleaning agent is not being used for this programme, add powder cleaning agent directly to the inside of the door.

Cleaning the coarse filter ^ Press the two lugs together, remove and clean the filter. ^ Put the clean filter back in position and press it until it clicks into place.
Cleaning and care Cleaning the spray arms Waste particles can lodge in the spray arm jets. The spray arms should be inspected and cleaned regularly (approx. every 6 months). ^ Use a sharp pointed object to push particles into the spray arm jets and rinse well under running water. Remove the spray arms as follows: ^ Unscrew the upper spray arm. ^ Remove the middle spray arm (on the top basket) by unscrewing the toothed wheel mechanism.
Cleaning and care Cleaning the drain pump and non-return valve The drain pump is situated under the non-return valve (see arrow). If water has not been pumped away at the end of a programme the drain pump or the non-return valve might be blocked. They are however, easy to clean. ^ Take the filter combination out of the wash cabinet. ^ Before replacing the non-return valve check that the drain pump is free of obstructions. ^ Carefully replace the non-return valve and secure with the locking clamp.
Cleaning and care Cleaning the filters in the water inlet ^ Replace filters and the seal. Make sure they are sitting correctly. Filters are incorporated in the screw connection of the water inlet hose to protect the water inlet valve. If these filters get dirty they need to be cleaned, otherwise insufficient water flows into the wash cabinet. ^ Reconnect the hose to the water inlet, making sure that it goes back on straight. ,The plastic housing of the water connection contains an electrical component.
Correcting minor faults With the aid of the following explanatory notes, minor faults can be corrected without contacting the Miele Service Dept. The wash cycle finishes too early and the p / 6 indicator light flashes (fault code F A appears in the display) Any work on the electrical components of the machine should only be carried out by a suitably qualified and competent person in accordance with local and national safety regulations. Unauthorised repairs could be dangerous. – The drain hose is kinked.
Correcting minor faults Water in the wash cabinet is not heated; the programme sequence lasts too long This machine has a resettable heater limiter which will switch off the heaters if they over-heat. This could be caused for example, by large articles covering the heating elements or if the filters in the wash cabinet are blocked. ^ Remove the cause of the fault. ^ Take off the service panel (see "Electrical connection").
Installation Please refer to the installation diagram supplied with the machine. ^ Open the door. ,Furniture and fittings installed near the machine must be of a commercial standard able to withstand the effects of steam and condensation. The machine must be installed correctly and levelled. Any unevenness in the floor level can be compensated for and the height of the machine raised or lowered by adjusting the four screw feet. The machine can be installed in the following ways: ^ Free-standing.
Installation Position and secure the machine To ensure stability the machine must first be aligned and then screwed to the worktop. ^ Open the door. Secure the machine to the front edge of the worktop using screws through the holes on the left and right hand sides of the front trim. ^ Do not use silicone sealant to seal the gaps between the machine and any neighbouring units as this would hinder ventilation to the circulation pump.
Electrical connection ,All electrical work must be Removing the plinth panel and the protective plastic cover: carried out by a suitably qualified and competent person in accordance with local and national safety regulations. ^ Connection should be made via a suitable isolator, with an on-off switch which should be easily accessible for servicing work.
Plumbing Connection to the water inlet ,Water in the machine must not be used as drinking water. ^ The machine must be connected to the water supply in accordance with local and national water authority regulations. ^ This machine is constructed to comply with German water regulations (DVGW), and may be connected to a suitable supply without an extra non-return valve if national regulations permit.
Plumbing ,The inlet hoses must not be shortened or damaged in any way (see illustration). See also the installation diagram supplied.
Plumbing Drainage ^ The drainage system is fitted with a non-return valve which prevents dirty water from flowing back into the machine via the drain hose. ^ The machine should preferably be connected to a separate drainage system on-site. If separate drainage is not available contact your Miele application specialist for professional advice. The on-site drain connection point should be sited between 0.3 m and 1 m above the lower edge of the machine. If it is lower than 0.
