Bosch Dishwasher Lights Flashing? What Each Pattern Means

Quick Answer

Bosch dishwasher lights flash for different reasons depending on which lights are flashing and how. All lights flashing together usually means a door latch issue or a power reset is needed.

Bosch dishwasher lights flash for different reasons depending on which lights are flashing and how. All lights flashing together usually means a door latch issue or a power reset is needed. The Start button blinking alone means the cycle was paused or interrupted. The Clean light flashing repeatedly on older models indicates an error code being communicated through a blink sequence. On newer models with a digital display, flashing lights supplement the error code shown on screen.

What Does the SYMPTOM Code Mean?

Bosch dishwashers use LED indicators in two ways: as status lights (normal operation feedback) and as error communication on models without a full digital display. Models with alphanumeric displays (most 300, 500, and 800 series from 2015 onward) show error codes directly as text. Older models and some current 100 series units use blink counts to communicate errors. Understanding which type of panel you have determines how to interpret the flashing pattern.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Door not fully latched triggering all-light flash40%
Cycle interrupted by accidental door opening24%
Error code being communicated via blink pattern (older models)14%
Child lock active causing specific button lights to illuminate solid12%
Water supply or drain issue triggering warning flash10%

Symptoms You May Notice

  • All control panel lights flashing simultaneously
  • Start button blinking but cycle not running
  • Single indicator light flashing repeatedly
  • Clean light flashing 7 times with pause, repeating

Can you reset a Bosch dishwasher to clear the SYMPTOM code?

Hold Start/Reset for 3-5 seconds to cancel any active cycle and clear most flashing states. If the flashing represents an error code, the code will return if the underlying issue is not fixed.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Identify which lights are flashing and the pattern

Note which specific lights are flashing: all lights together, just the Start button, specific cycle lights, or the Clean/Sanitized indicator. Also note the pattern: constant fast flash, slow regular blink, or a counted sequence with pauses. This determines the cause.

2

Check the door latch (all lights flashing)

3

Count blink sequences on older models

Frequently Asked Questions

All the lights on my Bosch dishwasher are flashing - is it dead?
No. All lights flashing simultaneously is almost always a communication error between the door latch sensor and the control board, not a sign of a failed unit. Open the door, close it firmly until you hear a click, and press Start. If all lights continue to flash after a solid door close, hold Start/Reset for 5 seconds to perform a soft reset. The unit is rarely dead when all lights are flashing.
The Clean light on my Bosch won't stop blinking - what does it mean?
On older Bosch dishwashers (pre-2015, especially those without a digital display), the Clean light blinking repeatedly after a cycle is the machine's way of signaling an error code. Count the blinks before each pause - that number corresponds to an error code (7 blinks = E7, for example). Newer models with digital displays show the code as text instead.
Lights are flashing but my Bosch dishwasher won't start
If flashing lights accompany a failure to start, the most common culprits are: door not latching fully (try pushing harder), child lock active (look for CL on display - hold the child lock button 3-5 seconds to clear), or an error code that must be resolved first (hold Start/Reset to drain and clear, then diagnose the error). See the Won't Start guide for a complete checklist.
How do I figure out which error code the flashing pattern matches?
On display-equipped models (300, 500, 800 series from approximately 2015 onward), the error code appears as text directly on the display (E15, E24, etc.). On older models or the 100 series, count the blink repetitions in one complete sequence before the pause restarts. That number is the error code number. The full error code list is in the Bosch Dishwasher Error Codes guide.
The Start button blinks after I opened the door mid-cycle - is that normal?
Yes, this is normal behavior. Opening the door during a cycle pauses the cycle and causes the Start button to blink, waiting for you to press Start again to resume. If you do not press Start within a few minutes, some models will time out and cancel the cycle. Press Start once to resume from where the cycle paused.
