Step-by-Step DIY Fix Guide
- SAFETY: Unplug the dryer from the wall outlet.
- Check the lint filter is clean — overheating from a blocked filter can damage the drum sensor.
- Reset by unplugging for 30 seconds, then restoring power.
- If E24 returns, call Bosch Customer Support at 1-800-944-2904.
If the warning comes back after restart
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- Any recurrence after lint filter check and power reset
What This Error Means
Error E24 on your Bosch dryer means: The dryer has detected a fault in the drum temperature sensor circuit. This sensor monitors heat inside the drum and regulates the heating cycle. The machine's self-diagnostic system has detected this condition and stopped the current cycle to prevent further damage or unsafe operation.
The most frequent cause is failed drum temperature sensor (thermistor). Work through the causes listed below in order — starting with the simplest and most accessible.
Bosch's official guidance classifies E24 as a technician-only fault. The components involved require electrical testing equipment and safe internal access. Contact Bosch Customer Support at 1-800-944-2904.
Electronics faults prevent the dryer from operating safely and the machine is right to stop. A 30-second power reset resolves occasional transient faults. If the code returns, the component needs physical diagnosis — there is no further DIY path.
Most Likely Cause by Symptom
The Bosch dryer may stop, pause, or refuse to complete the cycle normally.
Likely cause: Failed drum temperature sensor (thermistor)
Check first: SAFETY: Unplug the dryer from the wall outlet.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Wiring fault between drum sensor and control board
Check first: Check the lint filter is clean — overheating from a blocked filter can damage the drum sensor.
Common Causes
- Failed drum temperature sensor (thermistor)
- Wiring fault between drum sensor and control board
- Sensor damaged by prolonged overheating due to blocked lint filter
What Not to Do
- Do not run further cycles — uncontrolled temperatures may result from sensor failure
Model and Display Variation Notes
Model-family notes
- Bosch dryer display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Service option
Bosch service visit if the warning returns after the basic checks are complete.
Manual and model check
Check your exact model and manual before ordering any Bosch dryer parts.
Common parts
- Drum temperature sensor/thermistor ($15–$40)
- Wiring harness section if wiring is damaged ($20–$50)
This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
When Not to Keep Troubleshooting
Any recurrence after lint filter check and power reset
How to Prevent It Recurring
- Clean lint filter after every cycle — the primary cause of sensor damage is overheating from blocked airflow
- Check the exhaust vent duct annually for lint buildup
Related Error Codes
E08
The dryer has detected an electronics fault in the NTC (negative temperature coefficient) sensor circuit. The NTC sensor monitors drum or exhaust temperature to control the heating cycle.
E25
The dryer has detected a fault in the moisture sensor circuit. The moisture sensor detects when laundry is dry and signals the control board to end the cycle.
E06
A fault has been detected in the dryer's heating circuit. The dryer cannot generate the heat required to dry laundry.
