Maytag Washer Error Code 25

Error code 25 means the main control board detected a failure in Rotary Switch 1, which sits to the left of the encoder, during startup. The board runs a self-check before each cycle, and if it cannot get a valid signal from this switch, it stops the machine and displays the code. The encoder assembly or its wiring harness are the most likely sources of the problem.

No, the washer will not run a cycle while error code 25 is active. The control board halts operation at startup when it cannot confirm a valid signal from Rotary Switch 1, so the machine will not progress past this fault. Continuing to try to force a cycle will not bypass the error.

Yes, directly. The encoder assembly contains multiple rotary switches, and code 25 specifically points to Rotary Switch 1 on the left side of the encoder failing during startup. The encoder tracks cycle and drum position data for the control board, so a fault in one of its switches prevents the machine from operating safely.

Start by unplugging the washer for a few minutes and plugging it back in to see if the code clears as a one-time glitch. If code 25 returns, inspect the wiring harness connected to the encoder assembly for loose connectors, broken wires, or corrosion. Reseat any loose connectors and retest. If the code persists, the encoder assembly likely needs replacement, and a technician can confirm this with a diagnostic check.

If the fix is a loose or damaged wiring harness connector, the repair may cost nothing beyond your time. If the encoder assembly needs replacement, parts typically range from $30 to $80 depending on the model, with professional labor adding $100 to $200. Diagnosing the fault yourself before calling a technician can help you avoid paying for unnecessary parts.
