Generally speaking, credit cannot be added to vouchers. New vouchers are released regularly.
Vouchers or any remaining credit on them cannot be exchanged for cash. Any remaining credit will remain on the voucher until the next time it is redeemed, or at the latest until the 3-year validity period has expired.
You can check the value of your voucher on [PLACEHOLDER - URL]. Just enter the individual voucher code and PIN.
You can also check the value of your voucher at your Vorwerk Store or by contacting customer service.
