Error 105 is a communication error between diplay module & control module. Can be caused by a number of things. 1. Faulty control module. 2. Faulty display module. 3. Faulty drain pump. 4. Faulty RPS board on motor. You would need to get a service person in to check & test all those parts & give you a price to repair before you decide if it is worth repairing or not.
