Bosch dishwasher leaves residue after every wash cycle, how can I fix this?

To address this problem, the following is recommended:

- Cleaning the filter: The filter traps food debris and, if clogged, can prevent effective washing. It is advisable to remove the filter once a month and wash it with hot, soapy water to remove accumulated debris.

- Checking the spray arms: The holes in the spray arms can become blocked with food debris or limescale, making it difficult to distribute water properly. It is important to inspect and clean them regularly to ensure proper operation.

- Use of adequate detergent: Choosing a detergent of poor quality or in insufficient quantities can result in poor cleaning, leaving sand-like residue on the dishes. It is essential to use a quality detergent and in the dosage recommended by the manufacturer.

- Water hardness control: Hard water contains high levels of minerals that can leave residues on the dishes and build up inside the dishwasher. To counteract this effect, it is recommended to use dishwasher-specific salt, which helps soften the water and improve washing efficiency.
