A dishwasher that fails 13 months in isn't automatically your problem — UK law gives you up to 6 years to claim a repair, replacement or refund if the fault was there from the start, not caused by wear and tear.
You're past the 6-month automatic-fault-assumption window, so you'll need to show the fault was inherent (present or developing from new) rather than wear and tear. A repair or replacement is the usual first remedy; a refund follows if that fails or isn't possible.
No — manufacturer warranty registration is separate from, and doesn't reduce, your statutory Consumer Rights Act protection against the retailer.
Limescale damage from not using the right settings, misuse, or damage from a known short-life part failing exactly when expected (with reasonable wear) generally isn't covered.
Yes — after one failed repair attempt you can choose a full refund (with a deduction for use, if you're well past 6 months) or a price reduction if you'd rather keep the appliance.
