We discuss the problem of classification of indecomposable representations for extended Dynkin quivers of type 𝔼̃₈, with a fixed orientation. We describe a method for an explicit determination of all indecomposable preprojective and preinjective representations for those quivers over an arbitrary field and for all indecomposable representations in case the field is algebraically closed. This method uses tilting theory and results about indecomposable modules for a canonical algebra of type (5,3,2) obtained by Kussin and Meltzer and by Komoda and Meltzer. Using these techniques we calculate all series of preprojective indecomposable representations of rank 6. The same method has been used by Kussin and Meltzer to determine indecomposable representations for extended Dynkin quivers of type 𝔻̃ₙ and 𝔼̃₆. Moreover, our techniques can be applied to calculate indecomposable representations of extended Dynkin quivers of type 𝔼̃₇. The indecomposable representations for extended Dynkin quivers of type 𝔸̃ₙ are known.
