E11

NTC Sensor Fault

Severity

Medium

If your Bosch Dryer is displaying the error code E11, the control board has detected a fault identified as "NTC Sensor Fault". Understanding the root cause helps you avoid an unnecessary service call.

Owner's Summary

A temperature sensor inside your Bosch dryer is giving inconsistent readings. This can cause cycles to end too early or too late. The sensor itself is an inexpensive part to replace.

Symptoms

Bosch dryer temperature readings erratic, E11 error code

Common Causes

Faulty NTC temperature sensor
Corroded sensor connector
Wiring fault to sensor
Control board ADC failure

How to Fix

1 Test NTC sensor resistance at room temperature
2 Inspect and clean sensor connector
3 Test wiring harness continuity to sensor
4 Replace NTC sensor if out of specification

Tools You'll Need

Multimeter Electrical Contact Cleaner Flashlight

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

E11 is generated when the control board's NTC sensor input shows erratic or out-of-range values inconsistent with the expected resistance-temperature curve, suggesting a degraded or failing sensor rather than a complete open or short circuit.

Is It Safe to Keep Using?

No immediate safety risk. Fix within a couple of weeks.

Technician's Pro Tip

Erratic readings (rather than a constant open or short) often point to a cracked sensor housing letting in moisture. Inspect the sensor body for visible cracks before testing resistance values.
