Tools Needed:

• 15 mm Wrench
• Scouring pad or wire bristle brush

1. Remove the panels from the machine by following along with our guide: A53 Panel Removal

3. Remove the temp sensor with a 15 mm wrench.

4. Inspect the temperature sensor for scale build up or obvious wear. Clean or replace, then reinstall.
NOTE: It's a good idea to wrap the threads on the temperature sensor with a few layers of PTFE tape in order to ensure a good seal.
