Well, that depends. When we, Brabantia, replace the service part for you under warranty, the warranty period of the original purchase will continue to apply. This refers to the purchase of the complete product. Therefore, keep the original proof of purchase for as long as the warranty period runs, even after something has been replaced with the product.
Did you buy a service part yourself? Then a new warranty period starts. After purchasing a service part, you are entitled to a 2-year warranty on the relevant part. Always keep the proof of purchase, of a part too.
Brabantia service parts are not intended for resale.
