Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F12E5 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
