Suggestions needed...

Hi All,

Am in the US and have been using dishwasher since 2 years.I use it for washing pressure cooker ,aluminium kadhais ,non stick cookware, steel utensils other than china and glassware.I intially clean the dishes with water to remove the residual food and then load them into the dishwasher.I get clean dishes.

Now my question is that is it right to wash pressure cooker in the dishwasher.What are the other utensils that should not be washed in it.

Thanks & Regards,
