As long as you're not damaging the exterior, there's no set standard around how often or how much to pressure wash a house, but if repeated cleanings aren't removing the dirt and grime like you expect, make sure you're using the right detergent and using it correctly.

Homeowners with vinyl, metal, or composite siding should pressure wash their homes once a year. If you have wood siding, we recommend you pressure wash only when you have dirt or mildew buildup, unless you use very gentle pressure to wash away pollen or cobwebs on an annual basis.
Vinyl siding can withstand a powerful gas pressure washer (2,500-3,000 psi). Aluminum, stucco or soft-grain wood homes will do better with a less powerful washer (about 1,200-1,500 psi).
On normal paint, you won't damage it with a pressure washer, of course you should never put the nozzle right onto the paint, however normal washing won't cause damage, if anything it's preferable over a normal hose due to using less water and being able to remove more dirt and debris.
Vinyl siding: Using high pressure on vinyl could strip the protective sealant, leaving an uneven appearance to the siding. Paint: Painted surfaces are prone to chip, peel or discolor with applied water pressure. Roof shingles: Shingles can lose their granules, detach or break if immense pressure is applied.
