What does Electrolux Professional Epr6 mean?
Epr6 indicates a failure of the SkyLine oven's six-point core (food) probe. As with the single-point probe, probe-based cycles stop while time-based cycles remain available. The multi-point probe cannot read food temperature, usually because of probe misuse, a connector fault, or a failed probe element.
Symptoms
- Epr6 displayed
- Core-probe cooking cycles stop
- Time-based cycles still available
- Multi-point probe temperature not read
Common causes
- Food probe misuse, for example wire pulled or squeezed
- Connector failure
- Probe failure
- ACU failure

Diagnostic steps
Switch to time-based cooking
Run cycles based on time without the food probe to keep production going.
Inspect the probe and wire
Check for a pulled or squeezed probe wire, a common cause of this failure.
Use the USB probe if available
If available, use the accessory USB food probe as a temporary alternative.
Check the connector
A failed connector can cause the alarm; this is a service inspection point.
Call Service to restore the probe
Call Service to restore full probe functionality.
When to call a professional
Call an Electrolux Professional service centre to restore the six-point core probe after Epr6. The multi-point probe, its connector and the ACU require trained diagnosis to isolate the failed element or wiring. Because the probe drives precise core-temperature cooking and food-safety verification, do not rely on time-based cycles as a permanent substitute; schedule professional repair.
