Hello everyone any idea how i can find the backplate seal from the Hoover electron 600?

What’s wrong with the current one? With my machines I try to remove as much of the corrosion I can from the seal and backplate and the use silicone to make it watertight, makes it very annoying to remove but doesn’t leak.
