   Insufficient Water Temperature:

   • Proper water temperature is essential for effective cleaning in a dishwasher.
   • If the water temperature is too low, the detergent may not dissolve properly, and the cleaning action may be compromised.

2. Inadequate Water Pressure:

   • Low water pressure can prevent the spray arms from rotating effectively and distributing water evenly throughout the dishwasher.
   • Without sufficient water pressure, dishes may not be thoroughly cleaned, and food particles may remain stuck on surfaces.

3. Clogged Spray Arms:

   • Over time, food particles, mineral deposits, and other debris can accumulate in the spray arms, leading to clogs and reduced water flow.
   • Clogged spray arms can result in uneven cleaning and ineffective distribution of water across the dishes.

4. Improper Detergent Usage:

   • Using the wrong type or amount of detergent can affect cleaning performance in a Bosch dishwasher.
   • Too much detergent can lead to excessive sudsing, while too little detergent may not provide adequate cleaning power.

5. Hard Water Deposits:

   • Hard water contains minerals such as calcium and magnesium, which can leave behind deposits on dishes and interior surfaces of the dishwasher.
   • Over time, these mineral deposits can interfere with cleaning and result in cloudy or spotty dishes.

6. Blocked Filter or Drainage System:

   • A clogged filter or drainage system can impede water flow and prevent proper drainage, leading to poor cleaning results.
   • Food particles, debris, and mineral deposits can accumulate in the filter or drainage system over time, causing blockages.

7. Overloading or Improper Loading:

   • Overloading the dishwasher or improperly loading dishes can obstruct the spray arms and prevent water from reaching all surfaces.
   • Dishes should be arranged in the dishwasher according to the manufacturer’s recommendations to ensure proper water circulation and cleaning.

8. Solutions to Improve Cleaning Performance: a. Check Water Temperature:

   • Verify that the water temperature in your Bosch dishwasher is set to the recommended level (usually around 120°F or 49°C) for optimal cleaning.
   • Run the hot water tap at the sink before starting the dishwasher to ensure that hot water is available immediately.
