What information do you need to know beyond what I have provided?
Okay so the F5-E1 is a door latch error. , You will need to order and replace the door lock/latch assembly to fix the error. The link below is to the part you will need from a highly recommended company rated A+ with the Better Business Bureau. They offer a 100% money back guarantee, EVEN ON INSTALLED ELECTRICAL PARTS, for an entire year! They are the only company to allow returns on installed parts for a refund and offer a FULL ONE YEAR WARRANTY!
