4 PREPARATION

Tips for energy saving

Following information will help you use the product in an ecological and energy-efficient manner.

Wipe away any coarse food remnants on the dishes before putting them in the product.

Operate the product after filling it completely.

When selecting a programme, consider the table of "Programme data and average consumption values".

Do not put more detergent than suggested on the detergent package.

Water softening system

GRUNDIG GNF 41820 - Water softening system - 1

Your dishwasher requires soft water. If the hardness of the water is above 6^ dH, the water must be softened and descaled. Otherwise, ions that create the hardness will accumulate on the surfaces of the dishes and may adversely affect the washing, shining and drying performances of the product.

The product is equipped with a water softening system which reduces the hardness of incoming water. This system softens the supply water that enters into the product to a level that will allow washing the dishes with the required quality.

Adjusting the water softening system

Cleaning, rinsing and drying performance of your dishwasher will increase when water softening system is adjusted properly.

Adjust the new water hardness level according to the Water hardness level instruction in this booklet.

Use the test strip supplied with the product according to the steps given below to determine hardness level of your supply water.

GRUNDIG GNF 41820 - Preparation - 7112 345

Preparation

If the hardness level of the supply water is above 90 °dF or if you are using well water, then it is recommended to use water purification devices and special filters. If the hardness level of the supply water is below 13°dF, there is no need to use salt in your dishwasher. If this is the case, "No Salt Warning Indicator" (if any) illuminates continuously on the panel of your machine. If the water hardness level adjustment is set to level 1, the "No salt warning indicator" will illuminate continuously although it is not necessary to use salt. If you use salt under this condition, salt will not be consumed and the Salt indicator will not illuminate.

GRUNDIG GNF 41820 - Preparation - 1

If you move your house, it is necessary to readjust water hardness level of your machine by considering the information given above according to the hardness level of the supply water in your new location. Your machine will display the most recently adjusted water hardness level.

Adding salt

Water softening system needs to be regenerated in order for the product operates with the same performance continuously. Dishwasher salt is used for this purpose.

GRUNDIG GNF 41820 - Adding salt - 1

Use only special softening salts produced particularly for the dishwashers in your machine.

GRUNDIG GNF 41820 - Adding salt - 2

We recommend using granular or powder softening salts. Do not use salts that are insoluble in water such as table salt or common salt. Performance of water softening system may get worse in time.

GRUNDIG GNF 41820 - Adding salt - 3

Salt reservoir will fill with water when you start the product. Therefore, add the softening salt before starting the machine.

natural_image Illustration of a hand pouring liquid into a funnel on a stove (no text or symbols visible)

GRUNDIG GNF 41820 - Preparation - 3

You can put about 2 kg of softening salt into the salt reservoir.

  1. Replace the lid and tighten it securely when the reservoir is full.
  2. If you will not start a washing programme immediately after adding the salt, run the machine empty in the shortest programme to dissolve and wash away the scattered salt in the machine.

GRUNDIG GNF 41820 - Preparation - 4

Since different salt brands in the market have different particle sizes and since the water hardness may vary, dissolution of the salt in water may take a couple of hours. Therefore, Salt Indicator remains on for a while after adding salt into the machine.

Detergent

You can use powder, liquid/gel and tablet detergents in the machine.

GRUNDIG GNF 41820 - Detergent - 1

Only use in the detergents produced particularly for use with dishwashers. Never use washing up liquids. We recommend you not to use detergents that contain chlorine and phosphate as they are harmful for the environment.

GRUNDIG GNF 41820 - Adding detergent - 8

natural_image Hand placing a component into a device casing (no text or symbols visible)

GRUNDIG GNF 41820 - Adding detergent - 9

Use powder detergent in short programmes without prewash since the solubility of the tablet detergent changes depending on the temperature and time.

GRUNDIG GNF 41820 - Adding detergent - 10

Excessive usage of powder detergents will cause the detergent not dissolve completely and will also cause scratches on the glassware.

Combined tablet detergents

Combined tablet detergents exhibit water softening and / or rinse aid effect in addition to detergent effect. Some types of these detergents also contain special-purpose washing chemicals such as glass and stainless steel protectors.

GRUNDIG GNF 41820 - Combined tablet detergents - 1

The best washing performance in dishwashers is obtained by using detergent, rinse aid and water softening salt individually.

Combined tablet detergents are available as 3in1, 5in1, Allin1 etc. They function only up to a specific degree of water hardness.

Above this limit regeneration salt and rinse aid must be added. Refer to the instructions on the packaging of the combined detergent whether it is suitable for the hardness level of the water supply.

GRUNDIG GNF 41820 - Combined tablet detergents - 2

While using combined tablet detergents, contact with the detergent producers if your dishes are wet and/or if you notice limescale spots particularly on your glasses after the washing programme is over.

When you switch to powder, liquid/gel or tablet detergent from a combined tablet detergent:

  1. Make sure that salt and rinse aid reservoirs are full.
  2. Set the water hardness to the highest level and perform an empty run.
  3. After the empty washing cycle, review the user manual and readjust the water hardness level so as to suit the water supply.

  4. Make the appropriate rinse aid settings.

GRUNDIG GNF 41820 - When you switch to powder, liquid/gel or tablet detergent from a combined tablet detergent: - 1

Depending on the model, salt indicator and/or rinse aid indicator should be enabled again if they are disabled before.

Rinse aid

GRUNDIG GNF 41820 - Rinse aid - 1

The rinse aid used in dishwashers is a special combination that aims to increase drying efficiency and prevent water or lime stains on the washed items. For this reason, care must be paid to have rinse aid in the rinse aid reservoir and to use rinse aids produced specially for dishwashers only.

Please check the rinse aid indicator on the display to see whether there is adequate amount of rinse aid in the dishwasher or not. You need to refill the rinse aid reservoir with rinse aid whenever rinse aid warning indicator appears on the display of your machine.

  1. Open the lid of the rinse aid reservoir by pulling the latch in the direction of the arrow (B).

Decorative prints of chinaware as well as aluminum and silver items may get discoloured or tarnished after washing in the dishwasher just as it happens in handwashing as well. Some delicate glass types and crystals may become dull in time. We strongly recommend you to check if the tableware you are going to purchase is suitable for washing especially in the dishwasher.

Placing the dishes into the dishwasher

You can use your dishwasher in the optimum way with respect to energy consumption and washing and drying performance only if you place the dishes in an orderly way.

  • Wipe away any coarse food remnants (bones, seeds, etc.) on the dishes before placing them in the dishwasher.
  • Place thin, narrow pieces in the middle sections of baskets if possible.
  • There are two separate baskets in which you can place your dishes in the dishwasher. Place the heavily soiled and bigger items in the lower basket and smaller, delicate and light items in the upper basket.
  • Place the hollowed dishes such as bowls, glasses and pans upside down in the dishwasher. Thus, accumulation of water in deep hollows is prevented.

GRUNDIG GNF 41820 - Placing the dishes into the dishwasher - 1

To prevent possible injuries, always place the sharp and pointed dishes such as service fork, bread knife, etc. upside down so as their pointed ends will face down or they will lie horizontally in the dish basket.

Unload dishes in the lower basket first and then the dishes in the upper basket.
