how do i replace the rear legs on a Hotpoint bfi 620?

How do I relace the legs on a hotpoint bfi 620 as i recently bought a property with an integrated appliance that was giving a no water alarm.On removing the plinth the rear legs were bent at 90 degrees and it was propped up on 3 pieces of timber, i want to get it back on 4 legs so i can investigate the problem further
