What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Inspect the water-protection activation

    What they doContact Bosch service or a qualified appliance technician and provide the E15 code.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Close the water tap

    No special tools

    Close the dishwasher water-supply tap and leave the appliance out of use until it has been inspected.

    Do not tilt the appliance or bypass the protection system.
