I have a 2 yrs old front load washer does not start but F5E02 and E08 shows up when I press the start button.
What I should do or what is the problem?

Buy a good digital multimeter and learn how to use it. Here are the manuals you need to repair the machine: https://dl.dropboxusercontent.com/u/...e%20Manual.pdf
