A search for charged Higgs bosons decaying into W±W±W^pm W^pmW±W± or W±ZW^pm ZW±Z bosons is performed, involving experimental signatures with two leptons of the same charge, or three or four leptons with a variety of charge combinations, missing transverse momentum and jets. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider between 2015 and 2018 is used. The data correspond to a total integrated luminosity of 139 fb−1^{-1}−1. The search is guided by a type-II seesaw model that extends the scalar sector of the Standard Model with a scalar triplet, leading to a phenomenology that includes doubly and singly charged Higgs bosons. Two scenarios are explored, corresponding to the pair production of doubly charged H±±H^{pmpm}H±± bosons, or the associated production of a doubly charged H±±H^{pmpm}H±± boson and a singly charged H±H^pmH± boson.
