What E0 means on a Bosch dishwasher

E0 on a Bosch dishwasher is not a fault code. It indicates that the control board has no errors stored in its memory. When the diagnostic or error recall mode is accessed and E0 appears, the board is reporting a clean slate: no faults have been logged since the last memory clear or since the unit was manufactured or serviced. This is the expected response on a machine that is operating normally or has had its fault history recently reset.

For homeowners, seeing E0 means your dishwasher has not detected any problems with its internal systems. If you entered diagnostic mode intentionally or accidentally and saw E0, you can exit the mode and continue using the appliance normally. The control board continuously monitors components like the wash pump, drain pump, water inlet valve, heating element, and sensors. E0 simply means none of those systems have triggered a fault condition.

If you are seeing E0 after clearing a previous fault code, that confirms the reset was successful. If the original symptom that led you to check fault codes is still present, the issue may be intermittent and may not yet have been captured by the board, or it may be mechanical rather than electronic.

Common causes of E0

  1. 01

    Normal operation with no faults logged

    Wiring / connection

    The control board has no error history stored. This is the intended result when the machine is functioning correctly and all monitored components are within normal parameters.

  2. 02

    Fault memory was recently cleared

    Wiring / connection

    A previous error code may have been present but was erased through a diagnostic reset or power cycle sequence. The board now reports E0 because the memory was wiped before a technician could read it.

  3. 03

    Intermittent fault not yet captured by the control board

    Wiring / connection

    Some failures, such as a loose wiring connection or a component that fails only under certain conditions, may produce symptoms without triggering a stored code. The board reports E0 because the fault has not occurred in a way that crossed the detection threshold.

Frequently asked questions about E0

What does E0 mean on a Bosch dishwasher?
E0 means no error codes are stored in the control board's memory. It is not a fault. If you accessed the diagnostic or error recall mode and saw E0, the dishwasher has not logged any problems with its monitored systems. You can exit diagnostic mode and use the appliance normally.
Can I still use my Bosch dishwasher when it shows E0?
Yes. E0 is not a malfunction indicator. It confirms the absence of stored faults, so there is no reason to stop using the dishwasher based on this code alone. If the machine is displaying E0 but still behaving abnormally, the underlying issue may be mechanical or intermittent and has not yet been captured as a fault code.
Why does my Bosch dishwasher show E0 after I cleared an error code?
After a fault code is cleared through a diagnostic reset or power cycle, the board resets its stored error memory to E0. This confirms the reset was successful. If the original problem returns, a new fault code will be logged. Run the dishwasher through a full cycle and check for any recurring codes if symptoms persist.
How do I exit diagnostic mode after seeing E0 on a Bosch dishwasher?
Press and hold the Start button or the On/Off button, depending on the model, to exit diagnostic mode. On many Bosch models, opening and closing the door or pressing Cancel/Drain will also exit the mode. Refer to your specific model's service manual if button combinations vary, as Bosch uses several control panel layouts across its dishwasher lineup.
Does E0 on a Bosch dishwasher require any repair or cost anything to fix?
No repair is needed for E0 and there is no associated repair cost. It is a status indicator, not a fault. If a technician is charging to diagnose E0 as the only finding, the machine had no stored faults at the time of inspection. The only expense would be if a service call was made before reading the code, which is standard diagnostic labor.
