Lower Probe Reads Colder Than Allowed (Bosch Oven E223)

What E223 means

Your bottom oven goes cold mid-bake and E223 appears: the probe there is reporting less than the control accepts, and heating waits until the probe is unplugged. The manual starts with the food, because a probe stuck in something frozen reads low for an honest reason. Only after that does it move on to the probe's internal resistance, loose plugs and a pinched cable.

Common causes of E223

Probe stuck in food that is frozen or only part thawed
Probe sensing element worn out and reading too low
Slack plug or squeezed cable in the bottom oven probe circuit

✓ One safe check you can try

1. Take the probe out of the food and leave it to warm up to room temperature. 2. Try again with food that has completely thawed. 3. Frozen food is the first suspect and the only one you can rule out without tools. 4. If the code returns with thawed food, stop using the probe and call us.

! Why to stop there

The probe wiring passes through the cavity wall beside heating parts.
A loose connection and a dead probe give identical codes, and the wrong part wastes money.
Tugging on a pinched lead can snap it at the socket.

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.

E223E223 questions

Can I use the lower probe in frozen meat?

Not reliably, because a frozen center reads below what the control accepts. Thaw the food first, or leave the probe out and use a separate thermometer to check doneness.

Will the upper oven's probe still work?

Yes. Each cavity has its own probe and circuit, so a problem in the lower one does not normally disable the upper oven, and you can keep using it meanwhile.

How do I know if the probe is bad?

If E223 shows with thawed food and the probe is seated properly, the probe or circuit is the likely cause. We test both and give you a written price first.
