VERIFIED
E:9002 points toward power-supply fault on the applicable Bosch dryer platform. Keep the model/E-Nr with the code for accurate diagnosis.
When a Bosch dryer displays E:9002, the control has logged power-supply fault. That directs attention toward the electronic control path, but the code still needs to be read together with the exact model and what the appliance was doing at the time.
Treat the warning as a way to narrow the system involved. Do not bypass interlocks, protection devices, electrical safeguards, or sealed systems simply to make the code disappear.
At a glance
- Code: E:9002
- Appliance: Bosch Dryer
- Verified meaning: power-supply fault
- Primary diagnostic direction: the electronic control path
- Service-area context: San Francisco; confirm coverage by ZIP code
What the warning means
The verified technical anchor for E:9002 is power-supply fault. That wording should remain intact in the imported factual layer. The code narrows the fault path toward the electronic control path, but it does not automatically identify a single failed component.
Symptoms worth recording
Before changing settings or cycling power, note the behavior you can see or hear:
- The appliance can fail to start normally.
- A cycle might reset or stop.
- Other controls can behave intermittently.
- The code might appear after a supply interruption.
Possible causes from the source record
The source record supports considering the following possibilities without treating any one of them as confirmed:
- Incoming voltage outside the expected range.
- A loose or damaged electrical connection.
- An internal power-supply or conversion fault condition.
- A control board detecting unstable power.
First steps that stay outside the appliance
- Write down whether other household lights or appliances are behaving abnormally.
- Reset a tripped breaker only once and only when there is no sign of damage.
- Avoid measure or modify household wiring unless you are qualified to perform electrical work.
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.
When to stop using the appliance
Leave the appliance off for repeated breaker trips, sparking, burning odor, or visible wiring damage.
When diagnosis becomes the next step
If E:9002 remains active or comes back after the allowed external checks, move to model-specific diagnosis of the system associated with power-supply fault. Repeated resets or parts guessing will not identify the real failure path.
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
Use the exact Bosch model number when booking. It is the safest way to connect E:9002 with the correct technical documentation and related parts.
FAQ
For this record, E:9002 is associated with power-supply fault. 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:9002 display, the cycle stage or operating state where it appears, the visible symptoms, and the external checks already completed.
