Lower Cavity Overheated and Locked Itself: Bosch Oven E215

What E215 means

On a Bosch double oven, the bottom compartment climbed past its permitted temperature while the door was unlocked. The oven answered by stopping the heat and locking that door itself. When the temperature falls back within range, heating returns, the latch lets go and E215 clears. The checks named by the service list cover the element, the sensor resistance and stuck relays, all pointing to heat the controls never requested.

Common causes of E215

Lower cavity heating relay welded shut
Lower cavity sensor reading low, so the control keeps asking for heat
Element producing uncontrolled heat

✓ One safe check you can try

1. Turn the entire oven off at the breaker, not only with the controls. 2. If a relay has welded shut, the element stays live even with the display dark, and in a double oven that element is in the bottom compartment, out of easy view. 3. Leave it off, and do not try to open the locked door.

! Why to stop there

A relay that stays closed can keep an element glowing in a closed cavity.
Sensor, relay and element problems each lead to the same code and cost differently.
Working inside a double oven cabinet means reaching around live wiring.

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.

E215E215 questions

Why did the lower door lock itself?

Locking is part of the protection: when the cavity runs past its limit, the control closes the latch so the door cannot be opened onto extreme heat.

Is the upper oven also at risk?

They share a control module, so we check both cavities on a visit. Until then, we suggest leaving the whole unit switched off at the breaker.

Will you tell me the cost first?

Always. We find which part is involved, give you a written price, and begin only when you approve it. Our repairs carry a 30-day workmanship warranty.
