Quick answer

On a Zanussi washer, EH0 (or EHO) means a problem with the power supply. Plug another appliance into the same socket to test it, never use an extension lead and reset the washer by unplugging it for 30 to 60 seconds.

Safety first

Stop and check this first

  • Mains voltage is measured by an electrician: do not open the socket or the washer. If the socket is warm or blackened, stop using it.

Safe checks you can perform

  • Socket test with another appliance
  • Direct connection, no extension
  • Reset

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Voltage and frequency at the socket
  • Do not attempt this professional task: Washer power supply check

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. Voltage and frequency at the socket

    What they doAn electrician uses a multimeter to measure the voltage, frequency and earth at the washer socket.

    They must show youthe measured voltage, frequency and earth values.

    In writingthe values measured and the conclusion about the wiring.

  2. Washer power supply check

    What they doWith the wiring correct, Zanussi's technician checks the mains cable and power electronics with the diagnostic tool.

    They must show youthe diagnostic reading and the failing part.

    In writingthe cause, the part replaced with its part number and the result of a test wash.

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. Socket test with another appliance

    No special tools

    Who:
    you, no tools.
    How:
    unplug the washer and plug another appliance you know works, such as a lamp or kettle, into the same socket.
    Result that matters:
    whether the problem is the socket.
    If the other appliance also misbehaves:
    it is a wiring problem; call an electrician.
    If the other appliance works:
    go on to the extension lead and the reset.
    Evidence to keep:
    note of the appliance tried and the result.

  2. Direct connection, no extension

    No special tools

    Who:
    you.
    How:
    if the washer is on an extension lead or power strip, remove it and plug the washer straight into the wall.
    Result that matters:
    ruling out the extension.
    If it works without the extension:
    leave it like that.
    If it was already direct or EH0 continues:
    do the reset.
    Evidence to keep:
    note of the connection.

  3. Reset

    No special tools

    Who:
    you.
    How:
    unplug the washer, wait 30 to 60 seconds and plug it back in.
    Result that matters:
    whether it was a brief supply variation.
    If it washes without the code:
    it was a one-off; note the date and the variant (EH1, EH2 or EH3).
    If the code returns:
    contact Zanussi's service.
    Evidence to keep:
    photo of the code, including the variant.

What it means

Zanussi says EH0 indicates a problem with the power supply. Its UK page lists the variants: EH1, supply frequency out of range; EH2, supply voltage too high; EH3, supply voltage too low. The washer monitors the power it receives and stops if it is outside its range. The cause is usually the socket or the wiring, but it can also be the machine itself; the code does not tell them apart.

Warnings and stop conditions

  • Higheditorial warning

    Mains voltage is measured by an electrician: do not open the socket or the washer. If the socket is warm or blackened, stop using it.

Symptoms and causes

Probable causes · in order

  • Socket or household wiringCommon

    If another appliance also misbehaves on that socket, Zanussi puts it down to wiring and asks for an electrician.

  • Extension leadPossible

    Zanussi says never to use an extension cable; removing it is the first test.

    Evidence: Washing Machine Error Code EHO / EH0: Causes and Fixes

  • Brief supply variationPossible

    A short rise or drop in voltage or frequency (EH1 to EH3) clears with a reset if it does not repeat.

    Evidence: Washing Machine Error Code EHO / EH0: Causes and Fixes

  • Washer electronicsPossible

    With the socket tested and the reset done, if EH0 returns, Zanussi refers you to its service.
