Bosch Oven Error Code E122
E122 means the meat probe is reporting a temperature above its allowed limit — or shorting, which reads the same way. A probe accidentally left in through self-clean is the classic cause. The oven stops heating until the probe is removed.
Also shown as: E222
Common causes
- Meat probe failed or overheated
- Probe receptacle damaged or its contacts shorted
- Probe left in the cavity during self-clean
What to check, in order
- Remove the probe from the oven — heating stops until it is out — and let it cool fully.
- Inspect the probe and its plug for heat damage, and never leave the probe in during self-clean: it is not rated for cleaning temperatures.
- Try the probe once cool; if its reading is wildly wrong or E122 returns immediately, the probe has failed.
- If a new probe shows the same code, the receptacle is the fault and needs a technician. E222 is the second-cavity version.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E122, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
