The warranty on new DEWALT pressure washers is as follows:

DEWALT pressure washers model year 2008 (black frames) have a 2 year all components covered warranty.

They can be returned to the retailer, with a receipt up to 30 days for an exchange or refund. After 30 days they would have to go to a DEWALT Factory service center for warranty repair. The DEWALT Factory service centers will not take anything back for an exchange, it would have to be repaired.
