VERIFIED
When a Bosch dishwasher shows E3100, the source record points to leakage protection activated after water was detected in the base. Use symptoms and model-specific checks to decide when service is needed.
If your Bosch dishwasher displays E3100, 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.
Treat the code as evidence, not a complete diagnosis. Record what the appliance does, complete only the safe checks that fit the exact model, and arrange testing if the warning remains active or comes back.
At a glance

What Bosch is detecting
The technical anchor for E3100 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, E3100 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 can continue running.
- Normal control response 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 E3100 to technical documentation. Similar-looking products can use different sensors, controls, pumps, motors, or diagnostic logic.
FAQ
For the source record used here, E3100 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 E3100 display, the cycle stage or operating state when it appears, the visible symptoms, and the safe checks already completed.
