Indesit dg6100w dishwasher, how do I take access and side panels off?

I have a leak on my indesit dg6100w dishwasher from underneath. The door gaskets look ok so I want to check to check inside and just cannot fathom out how to get the bottom access panel or side panels off. Treat me gently please, I am pretty handy, it wasn't working at all yesterday, cleaned the carbon inside micro switch and it worked except it now leaks!
