The invention concerns a method for washing the drying wire in a paper or board machine, in which method the drying wire is washed and/or dried by mea ns of a liquid and/or air jet (V, I) when the drying wire (F) runs in a dryer grou p in the dryer section of a paper machine while guided by drying cylinders (10), reversing rolls (11) or equivalent and by guide rolls (12). In the method, a washing liquid jet (V) is applied to the drying win (F) when the drying wire (F) runs substantially downwards from a drying cylinder (10) and/or when the drying wire (F) runs towards the next reversing roll (11) of equivalent or towards a guide roll (12). Further, the invention concerns a device for washing the drying wire in a paper machine, which devi ce (14, 16, 17, 18, 20, 21, 22, 23, 24, 25) is placed in a dryer group in the dryer section in the paper machine and which device comprises means for producing a liquid jet and/or an air jet (V, I) so as to wash and/or to dry the drying wire (F), respectively . The device is placed in the dryer section in the paper machine in the vicinity of the drying wire (F) so that the means for producing the liquid jet (V) direct the liquid jet towards the drying wire (F) when the wire runs substantially downwards from a drying cylinder and/or substantially before the dryingwire (F) runs onto the next reversing roll (11) or guide roll (12) or equivalent
