Risk level

High

Professional inspection is recommended.

Urgency

High

Quick answer

The dishwasher has detected a problem in its water protection system. First close the dishwasher's water tap, as Balay instructs, then contact Balay's official service.

Safety first

Stop and check this first

  • Do not reopen the tap to see whether the code clears: Balay says to close it and call its official service, and a leak can damage floors and cabinets.

Safe checks you can perform

  • Dishwasher tap closed
  • Visible water around the appliance
  • Code, model and serial number recorded

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Find whether there is a leak
  • Do not attempt this professional task: Check the water protection system

What a technician must be able to justify

A technician is coming

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. Find whether there is a leak

    What they doThe technician opens the base of the unplugged appliance and looks for water and its origin (internal hoses, seals, sump).

    They must show youa photo of the leak point or of the dry base.

    In writingwhere the water came from, or that there was none.

  2. Check the water protection system

    What they doIf there is no leak, the technician tests the water-detection component and its connection to the board with instruments.

    They must show youthe failing measurement or test against the manufacturer's specification.

    In writingpart number replaced, the reason and a test run without the 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. Dishwasher tap closed

    No special tools

    Who:
    you.
    How:
    close the shut-off valve that feeds the dishwasher, usually under the sink.
    Result that matters:
    stopping the water supply, which is Balay's first instruction.
    If the code stays after closing the tap:
    that is normal; the alert stays recorded for the technician.
    If you cannot find the dishwasher's valve:
    close the home's main water valve until the visit.
    Evidence to keep:
    photo of the closed valve.

  2. Visible water around the appliance

    No special tools

    Who:
    you, with the dishwasher switched off and unplugged.
    How:
    look at the floor in front of and beside the dishwasher and inside the sink cabinet, without removing the kick plate.
    Result that matters:
    whether there is water outside the appliance.
    If there is water:
    dry it and do not reopen the tap; tell the technician where it was.
    If there is no water:
    the leak may be hidden or the fault may be in the monitoring system; do not open the appliance to check.
    Evidence to keep:
    photos of the floor and cabinet with the time.

  3. Code, model and serial number recorded

    No special tools

    Who:
    you.
    How:
    photograph the code on the display and the dishwasher's rating plate (model and serial number; on many models it is visible when the door is open).
    Result that matters:
    that the technician gets the exact code and model before the visit.
    If the same code returns after the previous check:
    you already have the proof for Balay's official service.
    If a different code appears:
    note it too; it points to a different page.
    Evidence to keep:
    dated photo of the code and photo of the rating plate.

What it means

Balay links E15 to a problem with the water protection system and gives two instructions: close the dishwasher's tap and contact its official service. Its job is to protect the home against water damage, so the alert can come from a real leak or from a fault in the system itself. Balay uses the same wording for E14 and E15. The code does not say which part has failed: the technician's inspection decides that.

Warnings and stop conditions

  • Highsource verified

    Do not reopen the tap to see whether the code clears: Balay says to close it and call its official service, and a leak can damage floors and cabinets.

Symptoms and causes

Probable causes · in order

  • Water leak inside or outside the appliancePossible

    If you see water on the floor or under the cabinet, the leak is real and closing the tap is urgent. If you see none, the leak may be hidden in the base.

    Evidence: Balay España códigos de error del lavavajillas

  • Fault in the protection system itselfPossible

    The alert can come from the component that monitors water even without a leak. Only the technician's internal inspection separates it from a leak.
