Question

I have a Black & Decker steam iron. I use filtered water when filling it. Often while I'm ironing the water seems to leak out of the bottom plate and the ironing board pad is soaked. I have even been burned when lifting the iron and having hot water drip on my feet. Is it time for a new iron or is there a solution?
