You can do a power wash on a DPF filter, and this is more commonly found done in Europe. They pre-soak the DPF in a bucket with a DPF cleaning solvent for up to 4 hours, and then spend about an hour powerwashing debris out of the ceramic filter elements. I have read this is only good for removal of 40% of the Diesel Particulates and ash.
I recommend bringing the DPF canister to a diesel shop which can do an 18 -24 hour Thermal baking process. This removes upto 95% of the Diesel Particulates plus the ash, and you get an included power wash of the DPF.
If you don't have any local DPF cleaning service doing the thermal baking, you can find some shops actually encourage you to box up your DPF and do a 2-day express shipping to their office, they do a professional cleaning, and ship it back to you.
I might add, this is most likely what a Kioti dealer would do.....they would ship a DPF to Kioti Corporate in North Carolina, who will use a local DPF cleaning service, they will then return it back to the Kioti dealer for install on your tractor. If you get it back within 6-8 weeks your doing great. So I recommend just doing this process your self.
