We have investigated the three vector boson production in electron-electron collisions in the framework of the left-right symmetric electroweak model. The process occurs due to lepton-number-violating interactions mediated by Majorana neutrinos and triplet Higgs scalars. We find that only the reactions with a heavy gauge boson pair in the final state, {ital e}{sup {minus}}{ital e}{sup {minus}}{r_arrow}{ital W}{sub 2}{sup {minus}}{ital W}{sub 2}{sup {minus}}{gamma} and {ital e}{sup {minus}}{ital e}{sup {minus}}{r_arrow}{ital W}{sub 2}{sup {minus}}{ital W}{sub 2}{sup {minus}}{ital Z}{sub 1}{sup 0}, are phenomenologically interesting from the point of view of the Next Linear Collider. If the mass of {ital W}{sub 2}{sup {minus}} is 0.5 TeV and the mass of the heavy Majorana neutrino is of the order of 1 TeV, the cross section of both reactions is in the range 1 to 10 fb at {radical}{ital s} =2 TeV, depending on the mass of the doubly charged Higgs triplet {delta}{sup {minus}{minus}} , yielding a 1% background for the pair produciton of {ital W}{sub 2}{sup {minus}}. At the {delta}{sup {minus}{minus}} resonance the cross section can be as large as 1 pb.
