I dont have a place to upload the photos.. however, to me the colours seem quite dull.. i'm not sure if it is the focus or not, but the color do seem abit old..
wash out = too much light loh.
compensate by either:
1. minus exposure value (the plus/minus sign; not to be mistaken wif the flash compensation)
note: did u accidentally set this value to + and forgot to change back??
2. use smaller aperture/faster shutter spd
3. use higher iso (not recommended)
4. are u taking in bright sunlight? use ND filter
5. are u metering at the wrong place?
P.S. u can't much post processing if u pics are washed. meaning u can't make a washed out pic look normal. there's no color info to adjust at all.
