      Several reasons may prevent your Gram Dishwasher from starting. First, ensure the dishwasher is properly plugged in and switched on using the On/Off button. Check your indoor fuses and ensure the water inlet tap is open. Also, make sure the dishwasher door is fully closed and that the water inlet hose and machine filters are not clogged.

      To prevent food waste from remaining on dishes, avoid overloading the baskets and ensure dishes aren't leaning against each other; refer to the loading instructions. Use the correct amount of detergent as indicated in the programme table, and select the most appropriate wash programme. Clean the spray arms with thin objects to remove any food waste clogging them, and verify that the drain hose and filters are correctly fitted.

    Why are there whitish stains on my dishes after using Gram OM 6640-90 RT/1 Dishwasher?
    • A
      April GreerSep 2, 2025
      Whitish stains on dishes can result from several factors. Ensure you are using the correct amount of detergent as instructed in the programme table. Also, your rinse aid dosage and/or water softener setting may be too low; increase these levels. If you have hard water, increase the water softener level and add salt. Finally, check that the salt compartment cap is closed properly.

    How to remove rust stains on dishes from Gram OM 6640-90 RT/1 Dishwasher?
    • R
      rodriguezjosephSep 4, 2025
      Rust stains may appear if the stainless-steel quality of your dishes is insufficient, so use only dishwasher-proof sets. Adjust the water hardness level using the water hardness table if there's a high level of salt in the wash water. Ensure the salt compartment cap is properly closed and use a funnel when filling with salt to avoid spillage. For a poor mains grounding, consult a qualified electrician immediately.
