Electrolux Dryer H2 / B2 Error Code

H2 / B2 is a power-supply warning. Record the code and involve the electric utility or a qualified electrician rather than probing the outlet, terminal block, or dryer electronics.

Applies to Electrolux dryer using H2 or B2 for a power-supply condition

What the appliance detected

Detected condition

The dryer detected a power-supply condition outside normal operation.

What may contribute

Possible causes

  • The incoming electrical supply may be outside the expected condition.
  • A utility-side voltage problem or household electrical issue may exist.
  • An electric dryer can sometimes tumble with a partial supply problem while heating or other functions fail.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record H2 or B2

    • Photograph the display and note whether there was a recent outage, flicker, utility event, or electrical work.
    • Note any accompanying no-heat, no-start, or breaker-tripping symptom.

  2. Check only safe household indicators

    • Confirm whether other circuits or large appliances show a power problem.
    • If the breaker has tripped once and there is no heat damage, follow the home electrical panel labeling and local safety guidance; do not repeatedly reset a breaker that trips again.

  3. Use the right professional

    • Electrolux directs owners to the electric company for this code.
    • Use a qualified electrician if the problem appears limited to the dryer branch circuit, receptacle, cord, or home wiring.

Actions not recommended

  • Do not measure 240-volt supply voltage unless you are qualified to perform that work.
  • Do not open the receptacle, terminal block, dryer cabinet, or breaker panel to diagnose the code yourself.
  • Do not keep resetting a breaker that repeatedly trips.

When to stop and request service

  • The utility reports normal service but H2 / B2 remains.
  • There is a hot plug, scorched receptacle, loose connection, arcing, or repeated breaker tripping.
  • A qualified electrician has not yet verified the branch circuit and supply.
