What do the red and green indicators mean on the GRAEF DA 506 dehydrator?
Frequently Asked Questions - 06/04/2026
Response Notice-Facile

The GRAEF DA 506 dehydrator is equipped with indicator lights that allow you to monitor the operating status of the device during dehydration.

Green indicator: The green indicator lights up automatically after confirming all temperature and time settings and pressing the START button. This indicates that the device is operating normally and the dehydration process has begun. The heating element is active and maintains the set temperature between 30 and 70 °C according to your settings.

Red indicator: Depending on the model, a red indicator may signal the initial heating or temperature adjustment phase before the device reaches the target temperature. It may also indicate that the device is entering standby mode or preparing to start the dehydration process.

The digital display panel of the GRAEF DA 506 shows you in real-time the current temperature and the remaining dehydration time, which complements the information provided by the indicators. Once the timer reaches 00:00, the dehydration is complete and you can turn off the device.

These visual indicators simplify the use of your dehydrator and allow you to quickly check that the drying process is proceeding correctly.

How to check if the GRAEF DA 506 dehydrator reaches the set temperature?
Frequently Asked Questions - 06/04/2026
Response Notice-Facile

The GRAEF DA 506 dehydrator features a built-in digital display that shows the current temperature of the device in real-time. Unlike other models, you do not need an external thermometer to check if the temperature is correctly reached: the control screen immediately indicates whether the temperature matches the one you have set.

To check the temperature at startup, simply turn on the device and consult the digital display. After setting the desired temperature (between 30 and 70 °C), press the START button to confirm: the device will then activate and begin heating until it reaches the defined temperature. The green light will turn on, indicating the start of the dehydration process.

Thanks to the Dry Balance technology of the DA 506, you benefit from uniform heat with an accuracy of ±5 °C. This means that the temperature varies very little between the different zones of the device, ensuring even drying of your food. You can therefore trust the digital display: the actual temperature is reliable and corresponds to the one you have set.

If you want an additional check, you can place a food thermometer on one of the 6 trays a few minutes after starting. It will confirm that the digital display of the device is correct. However, note that Graef recommends trusting the built-in display, which is calibrated to ensure accuracy.

After use, always check that the drying cycle is complete (timer at 00:00) before turning off the device and removing your food.

REQUIREMENTS ON THE INSTALLATION LOCATION

For safe and fault free operation of the unit, the following requirements of the installation location have to be met:

  • The unit has to be placed on a solid, flat, horizontal, and non-slipping surface with a sufficient weight-carrying capacity.
  • Make sure that the unit cannot topple over and does not stand directly in front of a wall.
  • Do not place the appliance on hot surfaces, such as hotplates, or near them.
  • Never use the appliance outdoors, and always keep it in a dry place.
    The unit is not designed for installation in a wall or a built-in cupboard.
  • Do not set up the unit in a hot, wet or moist environment.
  • Do not place the unit on paper / newsprint paper or loose surfaces. They might be drawn in and clog the ventilation slots. Make sure that the ventilation slots are not covered up.
  • Place the unit at least 30~cm away from a wall.
  • The socket has to be easily accessible so that the power cable can be removed easily in case of emergency.

ELECTRICAL CONNECTION

For safe and fault-free operation of the unit, the following requirements have to be met during the electrical connection:

  • Before connecting the unit, compare the connecting data (voltage and frequency)

on the type plate with those of your energy network. These details must correspond so that no damage occurs to the unit. In case of doubt ask your trained electrician.

  • The socket has to be protected at least by a 10 amps circuit breaker.
  • Make sure that the power cable is not damaged and is not laid across hot surfaces or sharp edges.

  • The connecting cable must not be stretched tightly.

  • The electric safety of the unit is ensured only when it is connected to a socket with protective conductor installed correctly. Operation on a socket without protective conductor is forbidden. If in doubt, let the house installation checked by a trained electrician. The manufacturer shall not assume responsibility for damage which has been caused by absent or interrupted protective conductor.

PRIOR TO FIRST USE

Prior to first use, wipe out the unit using a damp cloth. Then let the unit run for 45 minutes at 32^ in order to remove the moisture inside the unit. Clean the trays in warm water.

PREPARING THE DRIED MATERIAL

Use fresh and washed foodstuffs only. Do without using overripe fruit or vegetables. Prior to dehydration, remove stems, stones and the core. In order to maintain the colour of the dried material, sprinkle the fruit with lemon juice. Foodstuffs with a high sugar contents, such as apples, pears, peaches and bananas, are prone to darkening due to oxidation of sugar. Vegetables with a firm texture should be blanched for about 2 minutes in hot water before dehydrating them. In a small distance, put the foodstuffs side by side on the slide compartment. Select a distance to allow sufficient air to circulate. Do not place the foodstuffs on top of each other.

OPERATION

Prepare the foodstuffs to be dried.

IMPORTANT!

The thinner the foodstuffs were cut, the better they can dry. We recommend that you cut foodstuffs such as apples, lemons, oranges et cetera using our universal cutter. That way you will get even and thin slices. For smaller and thinner foodstuffs, we additionally recommend that you use the MiniSlice attachment. Using that unit, you can cut open mushrooms, tomatoes, strawberries, cucumbers, carrots et cetera extremely thin and evenly.

  • Take the trays out of the unit using oven clothes and put the foodstuffs to be dried on the trays.
  • Use the entire space of the trays, but make sure that there is sufficient space between the individual foodstuffs for air circulation. Overlapping of the food-stuffs impedes the dehydrating process.
    Using both hands, slide the trays back into the unit.
  • Switch on the temperature and the timer.

  • After completion of the dehydrating process (timer shows 00.00), switch off the unit.

USING SILICONE MATS OR BAKING PAPER

For foodstuffs which are damp or stick easily (e.g. tomatoes) we recommend that you use a silicone mat or baking paper. Put the silicone mat or the baking paper on the tray.

IMPORTANT!

Make sure that the baking paper does not cover the entire space of the tray. It should be easy for the warm air to pass through.

Put the silicone mat or the baking paper on the tray. At mid-term of the dehydrating time, the silicone mat or the baking paper can be removed.

STORING FOODSTUFFS

Before you stow the dried foodstuffs in a vessel, make sure that the foodstuffs are really dry. Moist foodstuffs easily get mouldy. Dispose of mouldy foodstuffs immediately. For storing foodstuffs use clean, dry vessels that can be closed airtight, if possible. Do not fill the dried foodstuffs into the vessel until they have cooled down.

PREPARING FOODSTUFFS

The following tables contain guideline values for the preparation of various fruits, vegetables and meat. The drying times depend on the ambient temperature, the relative air humidity and the moisture content of the foodstuff to be dried. When the moisture content is low, the drying time is at the lower end of the range. When the moisture content is high, however, the drying time is at the upper end of the range.

Please bear in mind that the drying times are also influenced by the number of foodstuffs on the trays. When drying foodstuffs, it is important to check the dryness of the product. When the product has not thoroughly dried, mould can form during storage (see food storage). In order to check the dryness, remove a slice of the foodstuff from the dehydrator and let it cool down to ambient temperature. Bend and divide the slice in order to test it for interior moisture.

IMPORTANT!

Please note that the above-mentioned particulars are indicative only and thus subject to correction.

REPROCESSING

During drying, water is removed from the foodstuffs. In order to restore their natural condition, process them with water. If you want to reprocess your foodstuffs, soak them in unsalted water for 3 - 7 minutes. Then prepare them as usual. If

you cook them, use the same water which you have utilised for soaking in order to preserve the nutrients. If you want to soak foodstuffs more than 1 hour, you should put them into the refrigerator to prevent bacterial growth. One cup of dried vegetable is reprocessed to approx. 2 cups. One cup of dried fruit is reprocessed to approx. 112 cups. The reprocessing times vary depending on the thickness of the foodstuff and the water temperature used. Warm water accelerates the reprocessing, but might lead to a certain loss of aroma.

CLEANING

IMPORTANT!

Pull the mains plug before each cleaning process.

Clean the trays in warm water using washing-up liquid, subsequently you can rinse them with clear water. Clean the dehydrator with a damp cloth. Neither put the dehydrator nor the trays into a dishwasher.
