What Does Error E03 Mean?

The Siemens dryer error E03 indicates a malfunction in the heating system, typically caused by a full condensate tank in condenser or heat pump models. If the condensate tank is full, the dryer will stop and display the E03 error, preventing it from heating properly. Additionally, heating circuit faults, such as issues with the heating element, thermostat, or NTC sensor, can also trigger this error, affecting the drying performance.

Common Symptoms:

  • Dryer stops and displays E03
  • Condensation reservoir full icon or message
  • Dryer fails to heat or achieve proper drying

Possible Causes

  • Full condensate (water) tank (medium)
  • Heating circuit fault (element/thermostat/NTC) (low)

How to Fix Error E03

DIY Fix Empty condensate tank (if applicable)

  1. Locate the condensate water tank on your condenser or heat pump dryer.
  2. Carefully remove the tank and pour out collected water.
  3. Reinsert the tank securely before restarting the cycle.

DIY Fix Check basic airflow and filters

  1. Remove and clean the lint filter after every cycle.
  2. Ensure condenser unit (if present) is clean and free of lint.
  3. Verify that air inlets/outlets are not blocked.

Technician Only Inspect heating components

  1. Disconnect power and access heater housing.
  2. Test heater element for continuity and physical damage.
  3. Check high‑limit thermostat and safety thermostat continuity.
  4. Test NTC temperature sensors per service specifications.

Parts needed: heater element assembly, high‑limit thermostat, safety thermostat, NTC temperature sensor

🛑 When to Call a Pro:
  • If E03 persists after condensate tank emptying and basic maintenance.
  • If unusual noises or burning smells occur during operation.
  • If heating faults are suspected but technical testing is not possible.
