E20 error - what 3 screws are holding the pump and electrical dashboard?

hi,
I've read the many responses about cleaning the bottom right drain area of the washing machine and done that. thanks.
However a few of the responses talk about taking out the pump - i cant see how to do that - where are the '3 screws' that people have mentioned.
also when resetting the FJDR 1466 washing machine, the indicator light just seems to flash in order through each of the options on the dashboard. is this normal and how long does it go on for?
