I haven't mowed for many months due to special circumstances so my yard's grass was pretty dense. Several time the motor stopped after grass formed a compact bulk completely blocking the blade. After the third time this happened, my Flymo Easimo Electric Wheeled Lawn Mower(Amazon link) doesn't start any more.
What is the likely cause and can I do something about it? I really don't feel like buying another one right now.
EDIT: There was no smell when opening the bonnet, and no disconnected wire or anything like that. Also I used the lowest setting (meaning the one to cut the grass as short as possible)
EDIT #2: I just tried again and the mower now works! Yet for 5 minutes trying an hour ago, nothing.
