Police said in a statement Thursday that officers stumbled upon the six-figure load while checking a house in western Amsterdam for unregistered residents on Monday.
The 24-year-old suspect was in the home at the time of the search.
A photo released by police shows the bundles of dirty bills — mainly 20- and 50-euro notes — packed into the laundry machine drum.
Officers also confiscated a money-counting machine, a gun, and several cell phones.
Police searched the house on the Oeverpad in Amsterdam Nieuw-West as part of a “ghost campaign” focused on unregistered people living in the city.
Properties are selected for ghost inspections based on signs of vacancy, crime, or strange habitation. Â
