What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Switch off the dishwasher, close the water tap, and leave internal diagnosis to Bosch service.
- Note whether the display says E09 or F09 and record the complete code before contacting support.
- Locate the dishwasher model number before calling; Bosch asks for it to identify the appropriate support path.
Applicability
Regional guidance · Bosch dishwashers covered by the US support page · United States
This scope follows Bosch's US dishwasher support page; E09 display wording and permitted actions can differ by exact model and market.
Reset or retry steps
- For models covered by Bosch US guidance, one 30-second breaker reset is permitted. If the code remains, contact Bosch support.
- Bosch Qatar directs E09/F09 owners to switch off, close the water tap and arrange service. Follow the guidance for your model and market.
When to call a technician
- Arrange Bosch service when the applicable regional guidance requires it, or if E09 remains after one permitted reset.
- Give the model number and complete display code; do not attempt internal tests.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first

- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this

FAQ
What does Bosch Dishwasher code E09 usually mean?
Bosch documents dishwasher E09 as a heat-pump internal-heater fault/error. Model context matters: Bosch US labels E09 a heat-pump internal-heater fault/error and calls for a 30-second breaker reset, then support if it is not resolved.
Can I keep using the dishwasher with code E09?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Switch off the appliance and close the water tap before arranging service for E09 or F09.
When should I call a technician for Bosch E09?
Arrange Bosch service when the applicable regional guidance requires it, or if E09 remains after one permitted reset. A qualified technician may check Heat-pump internal heater (the code does not identify a replacement part) against the model's service information before treating any part as failed.
