Why doesn't the pressure regulator valve work on my Tupperware 10117959000?

If the pressure regulator valve on your Tupperware Electric Pressure Cooker isn't working, it could be blocked. The pressure indicator valve is designed to release excess pressure as a safety feature. Inspect the regulator valve and cover to ensure they are clean and free from defects.
