The F5 E3 alert indicates there is an issue with the lid lock. Do not force the lid open, as permanent damage could occur. Remove any objects from the lid and clear any obstructions. Touch POWER to exit the cycle, then touch POWER again to release the lid.
Hi @appliancedummy,
Please confirm the model number of the washer?
Just in case the reset below doesn't fix the problem.
