Varying noise level

Noise level varies — Dishes not loaded securely

Bosch · Dishwashers

What does Varying noise level mean?

The noise level of the dishwasher changes during operation. This can be due to how dishes are loaded, items striking against each other, or water jets directly hitting the tub with a small load.

Common Causes

  • Dishes not loaded securely or resting on tines.
  • Dishes hitting each other.
  • Spray arm striking dishes.
  • Water jets directly striking against the tub with a small load.
  • Light items of dishware moving about during the wash cycle.

    Distribute the dishware evenly throughout the racks.

    Load the appliance with more dishware if you are running a very small load.
