Four vertical LEDs steady

Four vertical LEDs (cycle duration and clean indicators) all light up — Not an appliance error

Bosch · Dishwashers

What does Four vertical LEDs steady mean?

This is a status indicator, not an appliance error, suggesting an issue with drainage, water supply, or pump. The cycle duration indicators and the clean indicator LEDs will all be lit simultaneously.

Common Causes

  • Garbage disposal plug is still inserted or the drain hose is kinked.
  • Drain pump cover is loose or a foreign object is blocking the pump.
  • Filters in the water connection of the supply or AquaStop hose are blocked.
  • Inlet hose is kinked.
  • Water faucet is turned off.
