In short

A code points to a system (water, drain, heating, door, sensor, power), not necessarily a broken part. The same meaning can appear in different forms by model (4E vs 4C, for example). Some messages are reminders, not faults — like “OF OF” on a fridge. When a code appears: note it, do the safe checks, restart, and if it returns send the code and model to a technician.

Code logic: the system before the part

The control board constantly monitors sensors: did water arrive in time? Did temperature rise? Is the door locked? When an expected result doesn’t happen, it shows a code for the system that struggled.

A washer drain code, for example, means water didn’t leave within the set time — the cause may be a clogged filter or kinked hose before it’s a failed pump.

Why do codes differ between models?

Code families are similar, but the format varies with the display type and generation: you might see 4E, 4C or E1 for roughly the same idea. Some codes also exist only on specific models (such as ice-maker or heat-pump codes).

That’s why our code pages list “also shown as” and add a model note for every code.

The most common families

  • Water and filling: codes such as 4E on washers and 4C on dishwashers.
  • Draining: 5E on washers and 5C on dishwashers.
  • Door and lock: dE and LE/DC depending on the appliance.
  • Heating and temperature: HE, tE and tS.
  • Power and voltage: 9E on washers and dryers, 85E on fridges.
  • Electronics and communication: AE, bE and similar.

Messages that aren’t faults

  • “OF OF” on a fridge: demo mode that turns cooling off.
  • “Empty water” or “Clean filter” reminders on a dryer.
  • Child Lock and the lock icon.
  • The drum-clean reminder on a washer.

What to do when a code appears

  • Photograph the display and note the code exactly as shown.
  • Look it up on your appliance’s code page and do only the safe checks.
  • Unplug the appliance for a few minutes, then restart.
  • If the code returns, send the code, a photo of the model label and a short description to a technician.

Don’t try to open boards or covers — the code shows you where to look, but internal checks need tools and experience.

FAQ

If the code disappears after a restart, is the problem gone?

Not always — if the cause was temporary (like low water pressure) it may be, but if the code returns the cause is still there.

Why can’t I find my code online?

Some codes are model-specific. Send us a photo of the display and the model and we’ll help interpret it.

Can I clear the code from memory?

A restart usually clears the display, but what matters is fixing the cause, not hiding the code.
