12 Detergent

12.1 Suitable detergents

Only use detergents that are suitable for dishwashers. Both separate and combined detergents are suitable. For optimum washing and drying results, use separate detergent, adding Special salt → Page 22 and Rinse aid → Page 24 separately.

Modern, powerful detergents mainly use a low-alkaline formulation with enzymes. Enzymes break down starch and remove protein. Oxygen-based bleaching agents are generally used to remove coloured marks, e.g. tea or ketchup.

Note: Follow the manufacturer's instructions for each detergent.

Tip: Suitable detergents are available online via our website or from Customer Service → Page 48.

Tabs

Tabs are suitable for all cleaning functions and do not need to be measured out.

With shorter programmes tabs sometimes do not dissolve entirely and leave residues of detergent. This may impair the cleaning effect.

Powder detergent

Powder detergent is recommended for shorter programmes.

The dosage can be adjusted to the level of soiling.

Liquid detergent

Liquid detergent works faster and is recommended for shorter programmes without PreRinse.

Sometimes liquid detergent may leak out despite the detergent dispenser being closed. This is not a fault and is non-critical if you remember the following:

■ Only choose a programme without PreRinse.

■ Do not select timer programming for starting the programme.

The dosage can be adjusted to the level of soiling.

Separate detergents

Separate detergents are products that do not contain components other than detergent, e.g. powder detergent or liquid detergent.

With powder and liquid detergent the dosage can be individually adjusted to the level of soiling of the tableware.

For better washing and drying results and to avoid damage to the appliance, please additionally use Special salt → Page 22 and Rinse aid → Page 24.

Combined detergent

Besides conventional separate detergents, a number of products are available with additional functions. These products contain not only detergent but also rinse aid and salt replacement substances (3in1) and, depending on the combination (4in1, 5in1, ...), additional components such as glass protection or stainless steel cleaner.

According to the manufacturers, combined detergents generally only function up to a water hardness of 26 °E. With a water hardness above 26 °E you will need to add special salt and rinse aid. For the best washing and drying results we recommend using special salt and rinse aid from a water hardness of 17 °E. If you are using combined detergent, the washing programme is adjusted automatically to ensure the best possible washing and drying result.

12.2 Unsuitable detergents

Do not use detergent which could cause damage to the appliance or present a risk to health.

Hand washing-up liquid

Hand washing-up liquid can cause increased frothing and damage the appliance.

Detergent containing chlorine

Chlorine residue on tableware may present a risk to health.

12.3 Information on detergents

Follow the instructions on detergents in everyday use.

■ Detergents marked as "organic" or "ecological" (environmentally friendly) generally contain lower levels of active agents or completely dispense with certain substances. The cleaning effect may be restricted here. ■ Set the rinse aid and the water softening system to the separate detergent or combined detergent in use. - According to the manufacturers, combined detergents with salt replacement substances can only be used up to a certain water hardness, usually 26 °E, without adding special salt. For the best washing and drying results we recommend using special salt from a water hardness of 17 °E. ■ To prevent sticking, only touch detergents in a water-soluble pouch with dry hands and only ever place them in a dry detergent dispenser. ■ Even if the rinse aid and special salt refill indicators light up, washing programmes will run properly with combined detergents. ■ The function of rinse aid is limited with combined detergents. You will generally get better results using a separate rinse aid. ■ Use tablets with a special drying performance.

12.4 Adding detergent

  1. To open the detergent dispenser, press the locking latch.
  2. Add the detergent to the dry detergent dispenser.

50 ml 25 ml 15 ml

If you are using tablets, one is enough. Insert the tablets in a horizontal position.

If you are using powder or liquid detergent, follow the manufacturer's instructions and quantities for dosage in the detergent dispenser.

20 ml – 25 ml detergent is sufficient for normal soiling. If tableware is only lightly soiled, slightly less than the amount of detergent specified is usually sufficient.

Tableware

  1. Close the lid of the detergent dispenser.

CLICK

The lid clicks into position. The detergent dispenser will open automatically at the optimum time during the programme. Powder or liquid detergent will spread around the washing tank and dissolve there. Tablets will fall into the tablet collecting tray and dissolve in the right dosage. In order to ensure that tablets can dissolve evenly, do not place any other objects in the tablet collecting tray.

Tip: If you use powder detergent and select a program with pre-rinse, you can also add a little detergent to the interior door of the appliance.

13 Tableware

Only clean tableware that is suitable for dishwashers.

Note: Decorated glassware and parts made of aluminium or silver may fade or discolour with dishwashing. Delicate types of glass may turn cloudy after a few washing cycles.

13.1 Damage to glass and tableware

Only put glasses and china in the dishwasher if it is marked as dishwasher-safe by the manufacturer. Avoid damage to glass and tableware.

Cause Recommendation
The following tableware is not dishwasher-safe:■ Items of cutlery and tableware made from wood■ Decorated glassware, antique and hand-crafted tableware■ Plastic parts not resistant to heat■ Tableware made from copper or tin■ Tableware soiled with ash, wax, lubricating grease or paint■ Very small items of tablewareOnly put tableware in the dish-washer if it is marked as dish-washer-safe by the manufacturer.
The chemical composition of detergent causes damage.Use a detergent marked by the manufacturer as gentle on tableware.
Highly caustic alkaline or highly acidic cleaning solutions, in particular commercial or industrial cleaners, are not safe to use in the dishwasher with aluminium.If you are using highly caustic alkaline or highly acidic cleaning agents, in particular commercial or industrial cleaning agents, do not put aluminium parts in the dishwasher interior.
