Bosch Oven Error Code E1112: How to Fix It

Q: Is it safe to use my Bosch oven with error code E1112?

No, it's not safe to use the oven with error E1112. This error indicates the bake element relay is welded closed, meaning it cannot turn off properly, creating a fire hazard and potential for overheating.

Q: What causes a Bosch oven relay to weld closed?

Relay contacts can weld closed due to electrical arcing from power surges, age-related wear, moisture exposure, or excessive electrical load. High-use ovens or those in areas with unstable power are more prone to this issue.

Q: Can I replace just the relay or do I need the whole control board?

In most cases, you can replace just the individual relay if it's a plug-in type. However, if the relay is soldered to the control board or if there's damage to the board itself, the entire control board may need replacement.

Q: How much does it cost to fix Bosch oven error E1112?

A replacement relay typically costs $15-50, making this a relatively inexpensive DIY repair. Professional repair costs range from $150-300 including parts and labor, depending on your location and service provider.

Q: Will my oven warranty cover error code E1112 repairs?

Coverage depends on your oven's age and warranty terms. Relays are considered wear items, so they may not be covered under standard warranty after the first year. Check your warranty documentation or contact Bosch customer service for specific coverage details.
