Plastic discoloured (appliance)

Plastic parts inside the appliance are discoloured - Normal wear or low wash temperature

Bosch · Dishwashers Series 6

What does Plastic discoloured (appliance) mean?

Plastic components inside the dishwasher have changed colour over time. This is often a normal part of the appliance's life, or can be influenced by wash temperature or intensive precleaning.

Common Causes

  • Plastic parts inside the appliance may become discoloured during the life of the dishwasher.
  • Washing temperature is too low.
  • Tableware has been precleaned too intensely, causing sensors to choose a weaker programme.

Repair Steps & Checklist

  1. 1

    Understand that some discolouration is normal and will not impair functioning.

  2. 2

    Select a programme with a higher washing temperature if previous cycles were too cool.

  3. 3

    Only remove large remnants of food and do not prerinse tableware to allow sensors to detect appropriate soiling, preventing selection of weaker programs.
