    I already know what pot I have. I need to know how to fix it!!!!

    please post relevant answers only. Yes, I can pay $535 for service to replace two gaskets costing less that $3 each, but that is not economically feasible when a new machine is cheaper. I need to know how to replace the gaskets. Any other comment is a waste of time!
