Unox WF17

What does Unox WF17 mean?

WF17 is a partial breaking of the multipoint core probe. One or more sensing points within the multi-point probe have failed while others still work, so the oven warns that the probe is degraded. It continues to operate but multi-point core cooking accuracy is compromised.

Symptoms

• WF17 warning on the control panel
• Inconsistent core temperature across probe points
• Reduced reliability of multi-point cooking
• Warning recurs with the probe connected

Common causes

• One or more sensing points in the multipoint probe failed
• Damaged probe cable at a flex point
• Connector fault at the probe socket
• Probe nearing end of life

Diagnostic steps

1. 01

   Inspect the probe

   With power off, inspect the multipoint core probe and cable for damage, especially near the handle and bends.

2. 02

   Reseat the connector

   Disconnect and reconnect the probe at its socket to rule out a connection fault.

3. 03

   Measure the points

   Measure the probe to confirm individual sensing points are out of range, indicating partial failure.

4. 04

   Replace the probe

   Replace the multipoint core probe with the correct Unox part and retest multi-point cooking.

When to call a professional

WF17 indicates a degraded multi-point probe that should be replaced for accurate core cooking. If reseating the connector does not clear it, have a qualified Unox technician confirm the partial failure and fit the correct replacement probe.
