VERIFIED
When a Bosch dishwasher shows Flashing Active + Clean Lights, the source record points to drainage restriction involving the pump area, hose, or external drain path. Use symptoms and model-specific checks to decide when service is needed.
When Flashing Active + Clean Lights appears on a Bosch dishwasher, the control has registered drainage restriction involving the pump area, hose, or external drain path. That points the diagnostic process toward the drain path or water-removal system, but the display alone is not enough to choose a replacement part.
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.
At a glance
- Code: Flashing Active + Clean Lights
- Appliance: Bosch Dishwasher
- Verified meaning: drainage restriction involving the pump area, hose, or external drain path
- Diagnostic direction: the drain path or water-removal system
- Service area context: San Francisco; confirm coverage by ZIP code
What the code is pointing to
The technical anchor for Flashing Active + Clean Lights is drainage restriction involving the pump area, hose, or external drain path. 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 + Clean Lights should be used to narrow the troubleshooting path toward the drain path or water-removal system, not as automatic proof that one specific component has failed.
Operating signs to record
Before changing settings or cycling power, note what the appliance is doing. Useful observations include:
- Standing water can remain in the tub.
- Draining can sound slower or different.
- The program might stop before completion.
- The code can return at the drain stage.
Possible causes from the source record
Based on the source record, diagnosis may need to consider the following possibilities without assuming any one of them is confirmed:
- Blocked filter or pump area.
- Kinked or obstructed drain hose.
- Blocked air gap or disposal connection.
- Drain-pump or sensing fault.
First checks to make safely
- Turn the dishwasher off before user-accessible drain maintenance.
- Clean the removable filter if the model manual identifies it as a user-maintenance part.
- Verify the accessible pump-cover area only as described in the owner instructions.
- Look over the external drain hose for a sharp kink and check the air gap or disposal connection for an obvious blockage.
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.
When to stop using the appliance
If the accessible drain path is clear and the code returns, the pump, sensing, wiring, installation, or internal drain path requires model-specific diagnosis. When requesting service, include the complete Bosch model/E-Nr. Similar-looking dishwashers can use different controls, pumps, drying systems, and diagnostic logic.
If the code comes back
If the accessible drain path is clear and the code returns, the pump, sensing, wiring, installation, or internal drain path requires model-specific diagnosis. 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.
Use the complete Bosch E-Nr
Use the complete Bosch model/E-Nr when matching Flashing Active + Clean 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 + Clean Lights is associated with drainage restriction involving the pump area, hose, or external drain path. 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 + Clean Lights display, the cycle stage or operating state when it appears, the visible symptoms, and the safe checks already completed.
