Hotpoint Wt400 No Lights

Hello, I hope a kind soul can help with an issue I'm having with my washing machine as I'm a bit skint. The lights on my hotpoint wt 400 top loading hybrid washing machine no longer illuminate, it appears as there is no power. The washer came with the house I bought and worked a treat. It has a feed for hot and cold but I now only have cold supply so I put in a Y piece. The Y piece had a slight leak so I turned off the cold water supply until I found time to fix it. My cousin turned on the machine whilst I was out, when she came back the next morning it was dead, I've checked the fuse and outlet, but they are good. Another problem is I can't get access to the electrics or control panel at the back of the washer, the side panels come off easy, but this washer is a bit more complicated than any others I've opened before.

In a nutshell, please can you tell me....

1. What the most likely fault is?

2. How do I get access to the electrics and control board?

I've attached a picture

Thank you

Jay
