What Does Error 41 Mean?

The Westinghouse water heater error code 41 indicates a malfunction related to the heating element, often due to an irregular fan speed or blocked vent. This can result in no hot water and clicking sounds during operation. It's crucial to check for obstructions in the venting system and ensure proper functionality of the fan and ventilation components to resolve this issue.

Common Symptoms:

  • Error code 41 displayed on the water heater control panel
  • Unit may shut down or fail to operate normally when the error appears
  • Potential ventilation or fan abnormalities

Possible Causes

  • Fan speed too high while flame is on (medium)
  • Blocked vent leading to vent shutoff system activation (medium)

How to Fix Error 41

DIY Fix Check for Vent Obstructions

  1. Turn off the water heater according to the user manual safety procedures.
  2. Inspect the external vent termination for any visible blockages (debris, nests, snow, etc.).
  3. Ensure vent piping is properly installed and not crushed or restricted.
  4. Restart the unit to see if the error clears.

Technician Only Inspect Fan and Ventilation Components

  1. Isolate power and gas supply to the unit.
  2. Verify that the combustion fan motor operates correctly and that its speed sensor feedback is within spec.
  3. Check venting connections and fan assembly for proper orientation, balance, and absence of obstruction.
  4. Test or replace the fan speed sensor or blower assembly if irregular feedback or mechanical fault is found.

Parts needed: Combustion fan/blower assembly, Fan speed sensor, Vent piping and connectors

🛑 When to Call a Pro:
  • If repeated attempts to clear the error code do not resolve the issue
  • If there are signs of venting issues that cannot be safely accessed (e.g., rooftop vents)
  • If the fan assembly appears to be malfunctioning or producing unusual noises
