Maytag Washer Error Code E551

E551 means the internal traceability memory on your washer's control board is completely full. The traceability function is a built-in logging system that records operational events and fault history over the life of the machine. When that memory reaches its capacity, the control board triggers E551. The washer may still operate, but it can no longer write new log data.

E551 is not a safety-critical fault in the same way that codes related to overheating, flooding, or motor failure are. The code reflects a memory management condition in the control board rather than a dangerous mechanical or electrical failure. However, you should have the error diagnosed promptly, as a full traceability log may interfere with the board's ability to log future faults that could indicate real problems.

If the error can be resolved by clearing the traceability log through a diagnostic procedure, service call costs typically range from around $75 to $150 depending on your location and the technician. If the main control board requires replacement, total repair costs including parts and labor can range from $200 to $500 or more, depending on the specific model and board pricing.

Possibly, depending on whether your control board's firmware supports a diagnostic mode that allows the traceability log to be cleared. If such a mode is accessible, clearing the log may resolve the error without replacing any parts. If the firmware does not support log clearing, the repair typically requires professional service or control board replacement.

A standard power reset, such as unplugging the washer for a few minutes, is unlikely to clear E551 permanently because the underlying traceability memory remains full after a reboot. The error may temporarily disappear but will return. Clearing the log through a service diagnostic mode, if available, is the more effective approach.
