Meat Probe Reads Too Hot and Heating Stops, Bosch Oven E122

What E122 means

Partway through a roast, the oven quits heating and E122 comes up. The meat probe is sending back a number above anything the control will tolerate, so the elements stay off until the probe is unplugged. The usual story is simple: the probe was plugged in but left sitting on a rack or in the cavity, not pushed into the meat. In open air it climbs to oven temperature within minutes and trips the limit.

Common causes of E122

Probe connected but lying in hot air rather than inserted in the food
Probe sensing element worn out and reading too high
Damaged probe cable, or grime on the socket contacts

✓ One safe check you can try

1. Put on an oven glove, pull the probe plug from its socket and take the probe out of the cavity. 2. Run a regular bake with no probe attached. 3. If the oven heats as it should, then the probe, or the way it was being used, is the explanation and you may well be done.

! Why to stop there

The probe and cavity are hot, and handling them without protection causes burns.
A failed probe element and a misused probe give the same code, so replacing the socket wiring is a costly guess.
Forcing the probe plug into a dirty or damaged socket can bend its contacts.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E122E122 questions

Did I use the probe wrong?

Possibly. If it was plugged in but not inserted into the meat, it heats to oven temperature and trips this code. Always push the tip into the thickest part of the food.

Can I carry on baking without it?

Yes. Once the probe is unplugged the oven heats normally. An instant-read thermometer works fine for checking doneness while the probe stays out of service.

When does the probe itself need replacing?

If E122 returns even with the probe inserted correctly in food, the element or lead has likely failed. We confirm that and give a written price before replacing it.
