Setup
Unpacking and Placement
- Remove all packaging materials and inspect the ice maker for any damage.
- Place the ice maker on a stable, level surface, away from direct sunlight and heat sources.
- Ensure there is at least 15 cm of clear space around the unit for proper ventilation.
- Allow the appliance to stand upright for at least 2 hours before plugging it in, especially if it was transported horizontally. This allows the refrigerant to settle.
Initial Cleaning
Before first use, clean the interior of the ice maker:
- Open the lid and remove the ice basket.
- Clean the interior with a soft cloth dampened with warm water and a mild detergent.
- Rinse thoroughly and wipe dry.
- Ensure the drain plug at the bottom is securely closed.
Filling the Water Reservoir

A composite image illustrating the four main steps for using the ice maker: 1. Filling the water reservoir, 2. Turning on the machine via the control panel, 3. Scooping out produced ice cubes, and 4. Cleaning the unit.
Refer to Step 1: Wasser einfüllen (Fill Water) in the image above.
- Open the lid of the ice maker.
- Pour clean, cold drinking water into the reservoir up to the MAX fill line. Do not overfill.
- Close the lid.
Operation
Starting the Machine
Refer to Schritt 2: Die Maschine anschieben (Turn on the Machine) in the image provided in the Setup section.
- Plug the ice maker into a grounded power outlet.
- Press the Power button on the control panel to turn on the appliance. The indicator light will illuminate.
Selecting Ice Size
Press the 'Select' button to choose your desired ice cube size:
- S (Small): For faster ice production, suitable for crushed ice or smaller drinks.
- L (Large): For slower melting ice, ideal for beverages that require longer cooling.
Ice Production Cycle
The ice maker will automatically begin the ice production cycle. The first batch of ice (9 cubes) will be ready in approximately 8-10 minutes, depending on the selected size and ambient temperature. Subsequent batches will be produced more quickly.
- The 'Add Water' indicator will light up if the water level is too low. Refill the reservoir to continue production.
- The 'Ice Full' indicator will light up when the ice basket is full, and the machine will pause production. Remove ice to resume.
Scooping Ice
Refer to Schritt 3: Die Eiswürfel herausschaufeln (Scoop out the Ice Cubes) in the image provided in the Setup section.
Use the provided ice scoop to remove ice cubes from the ice basket. For best results, transfer the ice to a freezer for storage, as the ice maker is not a freezer and will melt the ice over time.
Maintenance
Regular Cleaning
Refer to Schritt 4: Einfache Reinigung (Easy Cleaning) in the image provided in the Setup section.
Regular cleaning ensures optimal performance and hygiene:
- Unplug the ice maker from the power outlet.
- Remove the ice basket.
- Drain any remaining water from the reservoir by opening the drain plug located at the bottom of the unit.
- Clean the interior with a soft cloth, warm water, and a mild, non-abrasive detergent.
- Wipe all surfaces dry.
- Close the drain plug securely.
- For self-cleaning function (if available on your model), consult the specific instructions in your included manual.
Storage
If the ice maker will not be used for an extended period:
- Perform a thorough cleaning as described above.
- Ensure the unit is completely dry before storing.
- Store the ice maker in a cool, dry place, away from direct sunlight and extreme temperatures.
