Good night Arturo. You can buy any spare that closely resembles the electrical characteristics of the original pump. Among other things, there are mainly 2 reasons why it is not recommended to buy spare parts other than the original, one because if you buy a pump of less than the original power, you probably cannot drain the volume of water in the estimated time for the washing machine, and runs the risk of taking this pump to life, eventually damaging it quickly. And the other reason is that if you buy a power pump greater than the original, if it is an electronic card washer, you run the risk of damaging the card element that controls the drain pump. Those are the reasons why, as far as possible you should buy the original spare part, you run less risk at the end of it all. In the case that you cannot buy the original, just make sure that the replacement you buy is of electrical characteristics almost identical to the original, not to mention the hose adaptations you may have to do. Regards!!!!
