What does the Active light flashing mean on a Bosch dishwasher?

The Active light flashing on a Bosch dishwasher indicates that the machine has detected a fault and interrupted an ongoing wash cycle. The Active light distinguishes a mid-cycle fault from a completed cycle or standby state. Depending on the model, the flashing Active light may appear alone or alongside other indicator lights or an alphanumeric error code that identifies the specific fault, such as a door latch issue, water inlet problem, drain blockage, or control board error.

Why is the Active light flashing on my Bosch dishwasher?

The Active light flashes on a Bosch dishwasher when the machine detects a problem during a wash cycle and stops operation to prevent damage or unsafe conditions. Common reasons include a door that was opened mid-cycle and not properly re-latched, a water supply fault preventing the dishwasher from filling, a drain blockage or pump fault preventing water from emptying, a leak detected by the AquaStop system, or a control board fault that has caused the cycle to abort unexpectedly.

What causes the Active light to flash on a Bosch dishwasher?

The most common causes of the Active light flashing on a Bosch dishwasher include a faulty or misaligned door latch preventing the door from registering as fully closed, a blocked or kinked water inlet hose reducing water supply to the machine, a clogged drain filter or blocked drain hose preventing proper water drainage, a triggered AquaStop leak protection system detecting water in the base of the machine, a failed circulation pump or drain pump, or a control board fault generating a general cycle interruption signal.

How do I fix the Active light flashing on my Bosch dishwasher?

Begin by opening and firmly re-closing the dishwasher door to ensure it is fully latched, then attempt to restart the cycle. If the Active light continues flashing, perform a hard reset by disconnecting the dishwasher from power for at least 5 minutes. After the reset, check and clean the drain filter at the bottom of the dishwasher tub and inspect the drain hose for blockages or kinks. Verify that the water supply valve is fully open and the inlet hose is not restricted. If the flashing persists after these steps, the door latch, inlet valve, drain pump, or control board may require professional inspection and replacement.

Can the Active light flashing on a Bosch dishwasher appear with an error code?

Yes. On Bosch dishwasher models equipped with a digital display, the Active light flashing will typically be accompanied by an alphanumeric error code such as E09 for a heating fault, E15 for a water leak detected by the AquaStop system, E22 for a blocked filter, or E24 for a drain fault. The error code provides a more specific diagnosis of the underlying fault. On older models without a digital display, the Active light may flash alongside other LED indicators on the control panel to communicate the fault category.

Can I fix the Active light flashing fault on my Bosch dishwasher myself?

Basic checks such as re-latching the door, performing a hard reset, cleaning the drain filter, and inspecting the inlet and drain hoses can be carried out at home and may resolve the fault if it is caused by a temporary interruption or minor blockage. However, if the Active light continues flashing after these steps, faults such as a triggered AquaStop system, a failed pump, a faulty door latch mechanism, or a control board error require disassembly of internal components and work near electrical and water systems. These repairs are best handled by a certified appliance repair technician to ensure safety and accuracy.

Bosch Dishwasher Active Light Flashing — Cycle Paused, Not a Fault

Informational Also described as: Active LED blinking

Quick Answer

The Active light flashing on a Bosch dishwasher simply means the current wash cycle has been paused — most commonly because the door was opened mid-cycle. This is normal operation, not an error. Close the door firmly and the cycle will resume automatically, or press Start if it doesn't restart on its own within a few seconds. If the Active light keeps flashing even with the door fully closed, that's when it's worth investigating further.

What Active Light Flashing Means

Bosch dishwashers use the "Active" light to show that a wash program is currently running. When the light flashes instead of staying solid, the machine is telling you the cycle has been interrupted or paused — most commonly because the door latch was released mid-cycle, whether intentionally (checking on a dish) or because the door wasn't fully sealed to begin with.

This is a built-in safety behavior: Bosch dishwashers won't spray water or run the pump with the door open, so the moment the latch releases, the cycle pauses and the Active light starts blinking to reflect that paused state. As soon as the door is closed and latched again, the cycle should resume from where it left off within a few seconds.

If the flashing continues well after the door is confirmed closed, the door latch or its sensor switch may not be registering "closed" correctly, which is worth a quick check before assuming anything more serious.

What to Do

Close the door firmly

Push the door closed until you feel and hear the latch engage. A door that's pushed shut but not fully latched won't register as closed to the machine.

Wait a few seconds, then check if the cycle resumes

Most of the time the cycle picks back up automatically within a few seconds of the door closing. Listen for the pump or spray arm restarting.

Press Start if the cycle doesn't resume on its own

If nothing happens after 30 seconds, press the Start button once to prompt the machine to continue.

Check the door latch and gasket if flashing continues

With the door closed, inspect the rubber door gasket for anything caught in it (a utensil, food debris) preventing a full seal. Also check that nothing is obstructing the latch mechanism itself.

If it still won't clear: a hard reset (unplug for 1 minute) often resolves a latch sensor that's stuck in the wrong state.

When to Call a Technician

Active light flashing rarely needs a service call, but consider one if:

The light keeps flashing even with the door confirmed fully closed and latched
A hard reset doesn't clear the flashing
The door doesn't latch securely anymore, or feels loose when closed
The signal appears alongside another light (see the Combined Signals page)

Frequently Asked Questions

Is the Active light flashing an error?

No. It simply means the cycle is paused, most often because the door was opened. It's a normal status indicator, not a fault code.

Why did the cycle pause when I didn't open the door?

If you didn't touch the door, the latch sensor may be misreading the door's position, or the door isn't sealing fully due to something caught in the gasket. Check the gasket for debris and confirm the door clicks fully shut.

Will my dishes still get cleaned properly if the cycle was paused?

Yes — once the cycle resumes, it continues from where it paused. As long as it completes the full program, wash results should be normal.

How long can the dishwasher stay paused before it's a problem?

There's no strict time limit, but if it sits paused for an extended period, hot water inside may cool and detergent may not perform as expected. It's best to close the door and let the cycle finish within a few minutes of it pausing.
