No, You are wrong, I'm afraid. You have 30 days where you can get an automatic refund after that you have numerous options but the main one is that they get one chance to repair it. You have a six month period where it is generally accepted that any fault was there when the product was bought unless there is obvious damage. Basically for the first 6 months the onus is on the retailer to prove that there was no defect. After that you have 6 years to make a claim - however this is the same for the 6 month part in that the fault has to have been present at the time of purchase. This is the same for all claims, i.e. you can't have introduced that fault through wear and tear/outright damage etc.
The difference after 6 months is that the liability shifts to you to prove it. However if many others are having the same problem, or there is an actual bug in the system which was present at the time then it will not be too difficult to prove.
On top of that you have the 2 year EU warranty and a manufacturers standard warranty - you can use and and all of those to get recourse.
If using the 6 year UK consumer rights act then you will not be entitled to a full refund if it can't be repaired, you will be refunded based upon the use made of the item in that period (for cars you can lose money for use after 30 days).
