What Does Error Code AE Mean on a Samsung Washing Machine?
Communication error — main and sub control boards not talking.
The AE code (also shown as AE6 or AC) fires when the main control board and the sub display/UI board fail to exchange data reliably over their communication harness. The board that detects the dropout halts the cycle, since neither can coordinate wash steps without a confirmed handshake. Unlike sensor or drainage faults, AE points to the boards' interconnection itself — most often a loose or corroded ribbon/harness rather than a mechanical or plumbing problem.
