i have not hear of any. But after the price of sending it back to korea and for servicing and all. It;s best to get a new pump. Recently there is a new pump which is cheap and effective. the Real Bubee. Available in shoppee
Promo terbesar expert care sudah dimulai, diskon hingga Rp.100.000 sedang berlangsung di shopee, ada juga voucher diskon 100% alias gratis bagi bunda yang beruntung. Buruan cek di https://shope.ee/9UfEMMqqTg (id-21517)
It maybe a wiser choice to get a new pump. You may end up saving some money.
thanks
