If your Bosch dishwasher displays E9001, the verified reference for this record is incoming household power supply is too low. 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.

What Bosch is detecting
The technical anchor for E9001 is incoming household power supply is too low. 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, E9001 should be used to narrow the troubleshooting path toward a model-specific operating system, 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 fail to start normally.
- A cycle can stop or reset.
- The display might show the code after power-up.
- Other household electrical symptoms can occur at the same time.
Systems and conditions to consider
- Low or unstable incoming supply.
- House wiring or connection problem.
- Supply condition outside the dishwasher’s expected range.
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
Leave the dishwasher off for repeated breaker trips, sparking, burning odor, or visible wiring damage.
When the next step is diagnosis
If the warning comes back, the incoming supply should be checked by a qualified electrician before appliance parts are replaced. 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 E9001 to technical documentation. Similar-looking products can use different sensors, controls, pumps, motors, or diagnostic logic.
FAQ
For the source record used here, E9001 is associated with incoming household power supply is too low. 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 E9001 display, the cycle stage or operating state when it appears, the visible symptoms, and the safe checks already completed.
