What Does Error E15 Mean?

The Thermador refrigerator E15 error code indicates a water leakage detection issue, often accompanied by a continuous beeping sound and a flashing display. It may suggest that the refrigerator compartment is too warm due to a fault in the temperature sensor or control board. Ensure that the refrigerator doors are fully closed and that vents are not blocked. If the issue persists, further diagnosis and potential replacement of the temperature sensor or control board may be necessary.

Common Symptoms:

  • Refrigerator internal temperature above setpoint
  • E15 code displayed on control panel
  • Potential cooling system not maintaining cold temperatures

Possible Causes

  • Temperature sensor fault (medium)
  • Control board / temperature regulation circuitry issue (medium)

How to Fix Error E15

DIY Fix Basic temperature checks and power reset

  1. Verify that the refrigerator doors are fully closed.
  2. Check that vents inside the refrigerator are not blocked by food items.
  3. Temporarily adjust the thermostat to the coldest setting and monitor if the temperature drops over several hours.
  4. Unplug the refrigerator for 5–10 minutes to reset electronics, then restore power and see if the E15 clears.

Technician Only Sensor and control board diagnosis/replacement

  1. Measure the temperature sensor resistance with a multimeter to confirm whether it matches expected values for the specific model.
  2. Inspect wiring harness and connectors between the temperature sensor and control board for loose or damaged connections.
  3. If sensor tests out of specification, replace with manufacturer‑approved part.
  4. If sensor is good but E15 persists with actual over‑temperature condition, evaluate the main control board and replace if necessary.

Parts needed: Temperature sensor / thermistor, Control board

🛑 When to Call a Pro:
  • If the refrigerator internal temperature rises dangerously high and food safety is at risk
  • If error persists after basic resetting steps and user cannot safely access internal components
