Water blockage on GSD2200D03

A recent well water plumbing problem clogged all my appliances with rust/iron and sediment on the pipes. My GE DW GSD2200D03 wont fill now. I need to clean the filter/trap/screen or whatever of mentioned debris. How is this done?
I have horrible well water…

Any help, pls?
Thanks Steve

Steve,

The water inlet valve is located under the dishwasher, on the left side behind the toe panel. It’s a good idea just to replace it instead of cleaning.
