What does Electrolux Professional H2OC mean?

H2OC is a SkyLine oven warning that the appliance is rechecking the water supply. The oven retries the water check three times every ten minutes; if water is still not detected, the EH2O alarm is shown. It is an early water-supply warning, typically caused by a closed tap, very low flow, or no signal from the flow meter.

Symptoms

  • H2OC warning displayed
  • Oven retries the water check periodically
  • Escalates to EH2O if unresolved
  • Weak or absent water flow

Common causes

  • Water tap is closed
  • Water flow rate less than 1 litre per minute
  • No signal feedback from the flow meter

Diagnostic steps

  1. Check the water tap

    Confirm the water tap is open.

  2. Check water pressure and flow

    Verify the water pressure is good and flow is above 1 litre per minute.

  3. Let the oven retry

    The oven rechecks three times every ten minutes; restoring supply may clear the warning.

  4. Call Service if EH2O rises

    If the problem persists for 30 minutes and EH2O appears, call Service.

When to call a professional

H2OC is a warning staff can often resolve by restoring the water supply. Call an Electrolux Professional engineer if it persists for around 30 minutes and escalates to EH2O, since the flow meter may be giving no feedback or there is a deeper supply fault. A flow-meter failure is an internal component, so professional diagnosis is needed once basic supply checks are exhausted.
