The easiest way to submit a Bosch dishwasher rebate is via the online claim form. If you wish to mail a rebate, fill out a printable mail-in form available through the Bosch appliance rebate page. The rebate form link is on the bottom right of the online landing page.
From the Bosch Appliance Rebate landing page, select the appropriate dishwasher tab. This opens up a page outlining the different rebates available and the valid dates for each one. Click on the Benchmark dishwasher tab to open the section on rebates for Benchmark dishwashers.
Check the expiration date on the offer before proceeding. Note that the offer is not available for machines purchased at certain sales outlets. As of March 2015, these outlets include Lowe's, Sears and Best Buy, as well as Pacific Kitchen and Home outlets outside of California.
Click on New Claim Entry to open up the online form. Click the Get Mail-in Form tab on the lower right to open the printable PDF form, if desired. The mail-in portion is on the last page of the PDF. Follow the instructions, and submit the purchase invoice or sales slip along with the completed form by the stated due date. Include model and serial numbers with the form.
