E7
Bosch Induction Cooktop
Severity: ModerateWhat it means
Bosch induction hob E7 means the temperature sensor (NTC) for a specific cooking zone is reading out of range — either open circuit or shorted.
The hob disables that zone to prevent uncontrolled heating.
The sensor sits directly under the glass at the centre of the coil and is the part that tells the hob the pan is getting too hot.
Without it, the zone is unsafe to run.
Affected Models
- Bosch Series 4 PUE/PUG induction hobs
- Bosch Series 6/8 PXE and PXY flexInduction hobs
- Bosch Combi-hobs after impact or a dropped pot
Common Causes
- NTC sensor failed internally (most common on units over 5 years old)
- Sensor wire harness disconnected during a service call
- Sharp impact on the glass directly over the zone (heavy pot dropped) cracked the sensor body
- Moisture seeped under the glass to the sensor — typical on hobs near a steam-heavy cooking area
- Control board input has failed (rare — usually shows E1 or E6 as well)
How to Fix It
-
Power-cycle the hob.
Switch off at the breaker for 60 seconds, then back on.
If E7 came up after a single odd event (a sloshed pot, a steam burst), the sensor may have read a transient spike that the hob latched as a fault.
A clean restart clears these — if E7 returns within a few zones of cooking, the sensor itself is bad. -
Test the other zones.
E7 normally identifies which zone is at fault by the position of the indicator (front-left, rear-right, etc.).
Use the other zones for cooking in the meantime — they're unaffected.
The hob is safe to use on the unaffected zones until you arrange a repair. -
Book a service call.
Have the model number ready — it's on the rating plate under the hob or in the original paperwork.
Tell Bosch service which zone shows E7.
If the hob is over 8 years old and the sensor failure is on a less-used zone, weigh the repair cost (typically £150-£250 fitted) against replacing the hob.
When to Call a Professional
Accessing the NTC sensor means removing the hob from the worktop and lifting the glass top.
This is not a DIY job — the glass is bonded with adhesive that needs careful release to avoid cracking.
A Bosch-authorised technician swaps the sensor in 40-60 minutes; a parts cost is typically £30-£60 plus labour.
