Bosch fridge-freezer E1 error code
E1 means fridge sensor fault. The fridge compartment temperature sensor is faulty or disconnected. The freezer may keep working but cooling control is degraded..
Often fixable at home · Fault type: Electrical/hardware
Safe checks, in order of likelihood
- Unplug the fridge for 10 minutes, then plug it back in — a transient sensor error often clears.
- Check nothing has knocked the display cable or wiring near the door hinge.
- If the code returns, the sensor or its wiring needs replacing.
Call a professional when…
Reset first; then the fridge temperature sensor (thermistor) usually needs replacing — a straightforward part swap behind the inner fridge panel. If the code returns after these checks, book a qualified engineer.
Parts usually involved
- Fridge thermistor / NTC sensor matching your model (E-number on the rating plate).
