Top lid won't open

For some reason, my washing machine is permanently locked. The power won't turn on even when we unplug and replug. I think there might be a spill that happened in the circuit. I just want to get my cloth out of the machine.

The model of the machine is a Samsung wa56h9000ap.

we've had it for over 3 years.

We still have the warranty, but the shop that sold it to us, Futur shop, closed down and is not owned by best buy. We're unsure if the warranty still applies, a warranty of 5 years.

How do I open the top locked lid?

Thanks in advance.
