Hi,
replacing the interlock is a easy procedure,its behind the front panel,
its the mechanism that holds the door closed,and it sounds like it failed on the drying cycle,hence the E10 error.
your primary error was the door interlock.Replacing the interlock is no guarantee of fixing this issue,
as I have mentioned it may have damaged the pcb,
if either yourself or partner doesn't feel confident undertaking such a repair,then maybe its time to call in a pro.
Take a look on youtube.espares have posted videos on wm repair,
replacing the interlock is one of those vids,similar model,but the exact same method,.
whatever you decide to do gud luck.
if you decide to diy and get stuck with any thing post back on here and someone will help.
