E2
Bosch Induction Hob
Severity: ModerateWhat Does This Error Mean?
E2 on a Bosch induction hob means the electronics overheated and thermal protection has shut the hob down. Allow 30 minutes to cool with the hob switched off, and check that nothing is blocking the underside ventilation.
Affected Models
- Bosch PUE611BB5E
- Bosch PVS775FB5E
- Bosch PIE631BB5E
- Bosch Serie 6 Induction
- Bosch Serie 8 Induction
Common Causes
- Cabinet ventilation slots beneath the hob blocked or inadequate
- Cooling fan failed or obstructed
- Simultaneous maximum-power use on multiple zones
- Hob installed without the required minimum air gap beneath
How to Fix It
-
Switch off at the cooker isolator and allow 30 minutes to cool.
Thermal protection requires a full cool-down before the hob will operate again.
-
Verify cabinet ventilation below the hob.
Bosch induction hobs require a minimum ventilation gap beneath the unit (specified in the installation manual). Check that no drawer, shelf, or liner is blocking the underside vents.
-
Listen for the cooling fan on restart.
After cooling, switch the hob back on and listen for the internal fan running. The fan should be audible within seconds. Silence or unusual noise from the fan indicates it may need service.
-
Reduce simultaneous zone usage.
Running all zones at maximum (especially Bosch PowerBoost zones) simultaneously generates significant internal heat. E2 under these conditions is a warning, not a fault — reduce the load.
Frequently Asked Questions
How do I clear E2 on a Bosch induction hob?
E2 clears automatically after the hob cools — switch off the hob, wait 30 minutes, then switch back on. If E2 returns within minutes of normal use, book a service to inspect the cooling fan.
Why does my Bosch hob show E2 even on low settings?
E2 on low settings is unusual and suggests either the cooling fan has failed (so even normal use causes overheating) or ventilation below the hob is severely restricted. Check fan operation and cabinet clearance.
