VERIFIED
E:3 points toward condensate tank or base group full on the applicable Bosch dryer platform. Keep the model/E-Nr with the code for accurate diagnosis.
A Bosch dryer showing E:3 has detected a condition tied to condensate tank or base group full. Similar product families can use different hardware, so the full model number is essential before the warning is interpreted too narrowly.
The steps below stay at the owner-safe level. They are intended to document the condition and check accessible items without opening protected systems or turning the page into a risky repair tutorial.
At a glance
- Code: E:3
- Appliance: Bosch Dryer
- Verified meaning: condensate tank or base group full
- Primary diagnostic direction: the drain and water-removal path
- Service-area context: San Francisco; confirm coverage by ZIP code
Technical meaning of the code
The verified technical anchor for E:3 is condensate tank or base group full. That wording should remain intact in the imported factual layer. The code narrows the fault path toward the drain and water-removal path, but it does not automatically identify a single failed component.
What you may notice
Before changing settings or cycling power, note the behavior you can see or hear:
- Water might remain where the cycle should have removed it.
- The drain stage can run longer than normal.
- The program might stop before completion.
- The pump can sound different or repeatedly attempt to run.
Systems and conditions to consider
The source record supports considering the following possibilities without treating any one of them as confirmed:
- A user-accessible filter or pump area restricted by debris.
- A kinked or blocked external drain hose.
- A blocked household drain connection.
- A pump, sensor, wiring, or control fault condition.
Checks to make before service
- Switch the appliance off before any owner-manual drain maintenance.
- Verify the visible drain hose for a sharp kink or crushing.
- Clean only the filter or pump-access area that the owner manual identifies as user-serviceable.
- Avoid reach into a pump area with power connected.
These checks are for information gathering only. Do not expose live wiring, bypass a safety device, defeat a door interlock, open a sealed refrigeration circuit, or perform undocumented service-mode procedures.
Leave the appliance off if
Leave the appliance off if water is leaking onto the floor or reaching electrical parts.
If the warning returns
If the accessible drain path is clear and the code returns, the pump, sensing, installation, wiring, or internal water path needs model-specific testing. Do not choose the most expensive module from the code alone. The technician should verify the relevant circuit or mechanism before recommending a repair.
For a service request, include what the appliance was doing immediately before the warning and which safe checks were already completed.
Why the full Bosch model/E-Nr matters
Bosch can reuse similar display characters across different dryer generations. Confirm the full model/E-Nr before applying platform-specific repair information.
FAQ
For this record, E:3 is associated with condensate tank or base group full. The exact model/E-Nr still matters because Bosch can use different hardware and diagnostic logic across product families.
Only if no stop condition is present and the appliance is otherwise operating safely. If the code repeats, normal operation is affected, or there is leaking, smoke, electrical odor, sparking, overheating, or repeated breaker trips, leave the appliance off.
Use only a normal reset that Bosch documents for the exact model. If the warning returns, repeated resets are not a substitute for diagnosis.
No. The code identifies a detected system condition. Model information, symptoms, and model-specific testing are still needed before a component is selected.
Have the full Bosch model/E-Nr, the exact E:3 display, the cycle stage or operating state where it appears, the visible symptoms, and the external checks already completed.
Bosch service in the San Francisco area
Ready to have Bosch E:3 checked?
If E:3 remains active or comes back, request Bosch dryer diagnosis for the San Francisco service area. Include the complete model/E-Nr, exact code, symptom summary, and ZIP code so service coverage can be confirmed.
Model compatibility: Bosch reuses codes across series and model years, so Bosch Dryer E:3 Error Code may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
