How to Reset a Bosch Dishwasher: All Methods

Updated · from manufacturer service documentation

A reset clears a displayed error code or an interrupted cycle and gives the control a fresh start — useful once you've already addressed (or ruled out) the underlying cause. It won't fix a genuine part failure on its own; if the same fault comes right back after a reset, that confirms the cause is still present.

Quick Reset: Cancel-Drain

To reset the dishwasher, push the Cancel-Drain (or Cancel-Reset, depending on model labeling) buttons at the same time. This is the standard everyday reset for a stuck or interrupted cycle.

Clearing Stored Error Codes: Customer Service Test Program

For a stored fault code rather than just an interrupted cycle:

  1. While pushing and holding any two wash cycle buttons, turn the dishwasher on with the on/off switch.
  2. After releasing the buttons, LED "B" lights and LED "C" flashes, confirming you're in the special programs menu.
  3. Push button "B" repeatedly until the digital display shows "P1" or until LED "C" is lit — this is the test program.
  4. Push button "C" to start the program; stored error codes will show on the digital display and LEDs.
  5. Run the customer service test program through to clear the stored codes.

Note: the test program can only be stopped or reset by pushing the on/off button — turning off the power directly does not exit it cleanly.

If the Code Comes Back

If the same error reappears right after a reset, the reset only cleared the display — it didn't fix the cause. Work through that specific error code's cause list rather than resetting repeatedly.

Frequently Asked Questions

What's the quickest way to reset a Bosch dishwasher?

Press Cancel-Drain (or Cancel-Reset) at the same time — this is the standard reset for a stuck cycle and doesn't require entering any special mode.

How do I clear a stored error code specifically?

Enter the customer service test program (hold two wash cycle buttons while powering on, then navigate to "P1") and run it through — this displays and clears stored fault codes, unlike the everyday Cancel-Drain reset.

Can I just turn the dishwasher off at the breaker to reset it?

Not cleanly if you're in the test program — the documentation specifically notes the test program can only be stopped by pushing the on/off button, not by cutting power.

Why does my display show a strange combination of letters/numbers?

Per the service documentation, this often happens when someone (a customer) held Cancel-Drain or Cancel-Reset while turning the dishwasher on, accidentally entering a test or special program mode — exit it with the on/off button rather than assuming it's a fault.
