Bosch Oven E222 Where the Lower Probe Reads Hotter Than Allowed

What E222 means

A roast in the bottom oven of a Bosch double unit suddenly goes cold, with E222 on the screen. The probe there is reporting a number above what the control will take, so that oven stops heating until the probe is unplugged. Start with the simplest explanation: the probe sat in the cavity without being pushed into food. Hanging in hot air, it reaches oven temperature in minutes.

Common causes of E222

Probe connected and resting in the cavity, not in the food
Probe sensing element worn out and reading too high
Worn probe cable, or grime on the lower socket contacts

✓ One safe check you can try

1. Put on an oven glove, since the probe will be hot, then unplug it from the lower socket and take it out. 2. Start the bake again with no probe. 3. If that cavity heats as normal, the probe, or how it was being used, explains the whole thing.

! Why to stop there

Both the probe and the cavity are hot, and handling them bare causes burns.
A failed probe and a misused one look the same until the bake is repeated.
Forcing a plug into a dirty 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.

E222E222 questions

Is this a lower oven problem only?

The code identifies the lower cavity's probe. The upper cavity has its own code and its own probe, so the upper oven can keep working normally.

What is the easiest fix?

Make sure the probe tip is pushed into the thickest part of the food. A probe left in open air heats to oven temperature and trips this error.

Does the probe need replacing?

Only if E222 returns while it is correctly inserted in food. We then test the element and the cable, and quote the repair in writing.
