E501 — Undocumented (Confirm for Your Model)
E501 is not in Bosch's official US oven/microwave error-code list (which documents only E11 — touch keys/condensation — plus generic 'E and a number' catch-alls). The 'meat probe jack' meaning below could not be confirmed and may reflect a temp-sensor vs. meat-probe mix-up. Verify the exact meaning in your model's manual or with Bosch service before acting.

How to fix it
- Unplug the meat probe — if E501 clears, the probe itself is the most likely cause.
- Inspect the probe tip and cable for damage; replace if any visible.
- Clean the jack with a dry cotton swab and a shot of contact cleaner; let dry fully before powering back on.
- Re-test with a known-good Bosch probe.
- If E501 persists with no probe inserted, the jack/harness or control input is bad.
