Quick answer

Balay says E22 warns of a blocked or dirty filter. Switch off and unplug the dishwasher and clean the filter at the bottom of the tub following your model's manual.

Safety first

Stop and check this first

  • Wear gloves when cleaning the filter housing: there may be fragments of broken glassware.

Safe checks you can perform

  • Filter at the bottom of the tub
  • Residue in the filter housing
  • Code, model and serial number recorded

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Inspect the water circuit beyond the filter
  • Do not attempt this professional task: Test with a clean filter

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 circuit beyond the filter

    What they doThe technician checks for blockages around the pump and in the internal ducts.

    They must show youthe object or blocked area.

    In writingwhat was cleaned or replaced.

  2. Test with a clean filter

    What they doThe technician runs a full programme and confirms E22 does not return.

    They must show youthe programme completed without the code.

    In writingthe work carried out.

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. Filter at the bottom of the tub

    No special tools

    Who:
    you, with the appliance off and unplugged.
    How:
    remove the lower basket, take the filter out as the manual shows and rinse it under the tap until no residue remains; refit it firmly.
    Result that matters:
    that the filter is clean and correctly fitted.
    If it was dirty and the code does not return:
    that was the cause.
    If it was clean or the code returns:
    move on to the next check.
    Evidence to keep:
    photo of the filter before and after.

  2. Residue in the filter housing

    No special tools

    Who:
    you, with the appliance unplugged.
    How:
    with the filter out, look into its housing and remove visible residue such as glass fragments, with your hand protected.
    Result that matters:
    that nothing loose is left to block it again.
    If there was residue:
    remove it and run a programme.
    If there is nothing and the code remains:
    call Balay's official service.
    Evidence to keep:
    photo of the housing.

  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, E22 warns that the filter is blocked or dirty, and its fix is to clean it following the manual. The filter traps food residue so water can circulate and drain. If the code returns after a thorough cleaning, visible dirt no longer explains it and Balay's official service should check it: the code does not identify a failed part.

Warnings and stop conditions

  • Loweditorial warning

    Wear gloves when cleaning the filter housing: there may be fragments of broken glassware.

    The cause Balay gives. You see it when you take the filter out: residue, grease, or bits of glass or plastic.

  • Blockage that returns after cleaningPossible

    If the filter was clean or the code returns soon, the origin is elsewhere in the water circuit and needs inspection.
