> Refunding is one possible remediation, see section 32 (cancellation) and section 26 (The consumer's rights in the event of defects). That option cancels the purchase contract, meaning you as the consumer give the item back, while the seller gives you the money you paid for the item.

Only if the manufacturer fails to fix it per section 31: "If the defect is not rectified and no redelivery takes place pursuant to sections 29 and 30"

Correct. They get one shot at correction, and if the fault isn't gone by then, refund it is (or the seller can just jump straight to a refund if they want to). You'd be surprised how often this happens.
