What Does Error E17 Mean?

The Bosch dryer error E17 indicates a malfunction in the lint screen temperature sensor (R3), causing the dryer to stop operation or fail to continue the cycle. This issue arises when the control board does not receive expected temperature or resistance readings from the sensor, resulting in a potential communication fault. You may notice the error during startup or mid-cycle without obvious overheating signs, indicating the need for further diagnosis or repair.

Common Symptoms:

  • Dryer stops operation or won’t continue cycle when E17 appears
  • Error occurs on display during startup or mid‑cycle
  • No obvious signs of overheating but sensor communication fault detected

Possible Causes

  • Faulty lint screen temperature sensor (R3 NTC) (medium)
  • Wiring harness/connectors damaged or loose for R3 sensor (medium)
  • Open or shorted circuit in sensor wiring (medium)

How to Fix Error E17

DIY Fix Basic inspection and reset

  1. Unplug the dryer from power.
  2. Visually inspect accessible wiring and connectors near the lint screen area for obvious damage or disconnections.
  3. Reconnect any loose connectors firmly.
  4. Plug the dryer back in and see if the error clears.

Technician Only Test/replace temperature sensor and repair wiring

  1. Disconnect power and access the internal NTC temperature sensor at the lint screen (R3).
  2. Use a multimeter to check wiring continuity and sensor resistance against expected values.
  3. Replace the temperature sensor if resistance is out of spec or wiring is damaged.
  4. Repair or replace damaged wire harness/connectors and reassemble.

Parts needed: NTC lint screen temperature sensor (R3), Wiring harness/connectors

🛑 When to Call a Pro:
  • If the error persists after basic inspection and reset attempts.
  • If there are signs of electrical damage, burning smell, or unclear wiring issues.
  • If unfamiliar with internal appliance diagnostics and handling.
