Questions and Answers

Before you call customer service

Water dripping out of the unit’s door

  • Door is not closed correctly.
    If the door is closed correctly, the door handle will point down on floor units.
  • Door seal is worn or damaged.
    Replace the door seal (see the „Maintenance” section of the manual).
    Care instructions for a maximum service life:
    - At the end of production, clean the door seal thoroughly with a damp cloth.
    - If lots of grilled products are cooked (considerable build-up of grease), then the door seal must also be cleaned with a damp cloth between cycles.
    - If the unit is to be operated for a long time without products, we recommend that the cooking cabinet temperature should not exceed 180 °C.
