The short answer
The short answer: F3 E4 says the control raised a reading the documentation answers by pointing at a technician instead of naming a part. Treat it as out of service until somebody with the service documentation has read it, and the cheapest of the likely causes is a one-off latch after a supply event, which a single power-down rules out.
This code, as the manufacturer publishes it
Reference| Code | Documented meaning |
|---|---|
| F3 E4 | The manufacturer publishes this code for this appliance without an owner-level meaning; it is documented for service diagnosis on the model lines that use it. |
What an owner observes
- The cycle stops and the display holds the code — It stays until the power is taken away.
- Nothing will start while the code stands — The control is refusing to commit rather than failing to respond.
- NEAR MISS - the code clears and never comes back — Then it was a latch, and there is nothing to repair.
What triggers this code, most likely first
- A one-off latch from a supply event — Ranked first because it is the only cause an owner can do anything about, and one power-down settles it.
- A connection inside the machine rather than a failed part — Second: connectors and harnesses account for a large share of codes that look like component failures from the outside.
The order to work through it
- Take the power away once and bring it back — Free, and it is the only owner-side test that tells you anything about this code.
- Resist the urge to keep restarting — Repeated attempts on an unknown fault add wear and tell you nothing new.
- Call with the code and the model details — The code is the most useful thing you have, and it is the reason the visit can be prepared for.
What you can do without tools
- Power the machine down at the breaker, then bring it back — One attempt, not five.
About 5 min
- Leave the machine unused if it involves heat or water — An unknown fault on a heating or filling appliance is not one to leave running unattended.
- STOP HERE - do not open the machine — Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off.
The safety line on this appliance
Safety
Isolate the appliance first. Unplug it or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Keep the wiring exactly as it was fitted, and if you find discoloured insulation or a browned connector, that is the fault to report rather than something to tidy up and carry on with.
When a reset is not the answer
Call immediately, and leave the appliance switched off at the breaker, if there is a burning smell, visible scorching, or a breaker that will not hold. In the ordinary case, this is a call rather than a repair: the manufacturer publishes no owner-level meaning for this code, and the diagnosis needs the service documentation for the model line and a meter.

How far this page applies
What this page covers is the code as documented for the model lines for which the manufacturer publishes this code without an owner-level meaning. It is general information about one reading, not a service manual for your unit: torque figures, connector pinouts and part numbers vary by family and are not printed here for that reason. Where a family-specific or model-specific page exists, it is the closer answer - start there, and use the index below to find it.
