Quick answer

Balay links E23 to a drain pump fault and asks you to call its official service. Switch off and unplug the appliance and do not use it until the visit, even if water remains in the tub.

Safety first

Stop and check this first

  • Do not keep running programmes with E23 to empty the tub: Balay says to call its official service, and forcing a failed pump does not fix it.

Safe checks you can perform

  • That the code is E23 and not E24 or E25
  • Appliance off and unplugged until the visit
  • Code, model and serial number recorded

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Measure the drain pump
  • Do not attempt this professional task: Check power from the board

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. Measure the drain pump

    What they doThe technician measures the pump winding with a multimeter and checks whether it turns freely.

    They must show youthe measured value against the manufacturer's specification.

    In writingthe result and the pump part number if replaced.

  2. Check power from the board

    What they doIf the pump measures correctly, the technician checks whether it receives power when the programme calls for draining.

    They must show youa complete drain test after the repair.

    In writingthe part replaced and the reason.

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. That the code is E23 and not E24 or E25

    No special tools

    Who:
    you.
    How:
    read the code on the display: E24 and E25 have user checks on Balay's page.
    Result that matters:
    which code is shown exactly.
    If it says E24 or E25:
    follow those pages before calling.
    If it says E23:
    Balay refers you to its official service.
    Evidence to keep:
    photo of the code.

  2. Appliance off and unplugged until the visit

    No special tools

    Who:
    you.
    How:
    switch off and unplug the dishwasher; if water remains in the tub, do not bail it out by taking parts off.
    Result that matters:
    not straining the pump with more programmes.
    If the code returns when you plug it in another day:
    it confirms the fault for the technician.
    If it does not return:
    note when it appeared; the technician needs to know.
    Evidence to keep:
    time of the alert and whether water remained in the tub.

  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

According to Balay, E23 warns of a drain pump fault, and to get the appliance working again you need its official service. It differs from E24 and E25, which on the same page have causes you can check (hose, siphon, blocked pump or loose cover). The code points to the pump, but the fault may be in the pump itself, its connection or the electronics that power it: only the technician's measurements separate them.

Warnings and stop conditions
