Step2: Open the access panel and locate the existing thermometer probe and capillary line inside the wash or rinse section.
Step3: Carefully remove the old thermometer by loosening the flange mount and disconnecting the probe without bending the capillary tube.
Step4: Position the new thermometer, secure the flange tightly, and route the capillary away from moving parts or heat sources.
Step5: Restore power, run a short cycle, and verify correct temperature readings and leak-free installation.
