From Old Spanish enxuto, from Latin exsūctus, past participle of exsūgō, from ex + sūgō. Compare Portuguese enxuto, Catalan eixut, Italian asciutto. In pre-literary Spanish, the word likely had the form *eissuito (compare also Old Portuguese enxoyto, Galician enxoito), and then underwent a change of prefix through influence from enjugar (the same process affecting other Ibero-Romance languages), with the ending being influenced by past participles such as roto, escrito, frito, etc. (as normally the Latin consonant cluster -ct- yields -ch- in Spanish; a form ensucho was attested, and ensuchu is used in Asturian, where it became the irregular past participle of ensugar).
