VERIFIED
Bosch dishwasher Flashing Active Lights is associated with leakage protection activated after water was detected in the base. Review the operating signs and safe external checks before deciding on the next step.
If your Bosch dishwasher displays Flashing Active Lights, the verified reference for this record is leakage protection activated after water was detected in the base. Because Bosch platforms can differ by generation, keep the complete model number with the code before making repair decisions.
Start with external observations rather than parts guessing. The goal is to confirm the conditions around the warning without bypassing safety devices or turning a diagnostic code into an unsupported DIY repair procedure.

What Bosch is detecting
The technical anchor for Flashing Active Lights is leakage protection activated after water was detected in the base. That description should remain unchanged when the page is imported. What can vary is the hardware behind the condition, so the model/E-Nr and the observed behavior are necessary context.
For this reason, Flashing Active Lights should be used to narrow the troubleshooting path toward a water-protection or leakage condition, not as automatic proof that one specific component has failed.
What you may notice
Before changing settings or cycling power, note what the appliance is doing. Useful observations include:
- The dishwasher can stop the program.
- The drain pump might continue running.
- Normal control behavior can become limited.
- Water can or might not be visible outside the cabinet.
Systems and conditions to consider
Based on the source record, diagnosis may need to consider the following possibilities without assuming any one of them is confirmed:
- Water entering the base from an internal or external leak path.
- Overflow or unwanted water migration into the base.
- A leak-protection trigger that needs its source identified.
What you can verify without opening the appliance
- Write down or photograph the exact code.
- Record the complete Bosch model/E-Nr.
- Follow only owner-manual checks that do not require panel removal or access to live parts.
These steps are meant to gather useful information without exposing live wiring, bypassing an interlock, defeating a leak-protection device, or opening a system the owner documentation does not designate for user access.
Leave the appliance off if
If water is near an outlet, plug, or electrical connection, avoid the wet area and leave the appliance off.
When the next step is diagnosis
The source of the water in the base must be found before normal use resumes. A reset cannot correct a leak. When requesting service, include the complete Bosch model/E-Nr. Similar-looking dishwashers can use different controls, pumps, drying systems, and diagnostic logic.
A useful service request includes the exact display, what the appliance was doing immediately before the warning, and which external checks were already completed.
Model and platform note
Use the complete Bosch model/E-Nr when matching Flashing Active Lights to technical documentation. Similar-looking products can use different sensors, controls, pumps, motors, or diagnostic logic.
FAQ
For the source record used here, Flashing Active Lights is associated with leakage protection activated after water was detected in the base. The complete model/E-Nr still matters because Bosch can use different hardware and diagnostic logic across product families.
Do not continue if the warning is accompanied by the stop conditions listed above. Water near electrical parts, leaking, smoke, a burning odor, sparking, or repeated breaker trips are reasons to leave the appliance off and arrange service.
Where the Bosch documentation for the exact model allows a normal power reset, use it once after recording the code. A returning warning means the underlying condition still needs attention; repeated resets are not a repair.
Not necessarily. An error code narrows the detected condition or system. The model number, symptoms, and model-specific testing are still needed before selecting a component.
Have the full Bosch model/E-Nr, the exact Flashing Active Lights display, the cycle stage or operating state when it appears, the visible symptoms, and the safe checks already completed.
