15STATEMENT STATEMENTOFLIMITEDPRODUCTWARRANTY

LIMITED PRODUCT WARRANTY

STATEMENT OF LIMITED PRODUCT WARRANTY
THIS LIMITED WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM STATE TO STATE.

15.1What this warranty covers & Who it applies to

The limited warranty provided by BSH Home Appliances (“Bosch”) in this Statement of Limited Product Warranty applies only to the Bosch appliance (“Product”) sold to you provided that the Product was purchased: ¡ For your normal, household (non-
commercial) use (i.e., no more than 7,000 cups during the warranty period), and has in fact at all times only been used for normal, noncommercial household purposes. ¡ New at retail from a BSH authorized dealer or directly from BSH (not a display, floor, “As Is”, or “B” stock appliances), and not for resale, or commercial use. ¡ Within the United States or Canada, and has at all times remained within the country of original purchase.
The warranties stated herein apply to the original purchaser of the product warranted herein purchased for ordinary household use during the term of the warranty. Please make sure to register your product; failure to register will not affect your warranty rights. Registering

en-usSTATEMENT OF LIMITED PRODUCT WARRANTY

Your product is the best way for Bosch to notify you in the unlikely event of a safety notice or product recall. Upon purchase or receipt of the product, it is recommended to register it using the QR code on the side of the machine or at https://registerbosch.com/

15.2Obtaining warranty service

To obtain warranty service for your product, you should contact Bosch Customer Service at (800)701-5231 to arrange a repair.
15.3How long the warranty lasts
Bosch warrants that the Product is free from defects in materials and workmanship for a period of seven hundred thirty (730) days from the date of the original delivery. The foregoing timeline begins to run upon the date of the original delivery. The warranty shall only be extended for the time that elapsed between the date of your warranty claim and the date of the completed repair or replacement. This Product is also warranted to be free from cosmetic defects in material and workmanship (such as scratches of stainless steel, paint/porcelain blemishes, chips, dents, or other damage to the finish) of the Product, for a period of thirty (30) days from the date of delivery. This cosmetic warranty excludes slight color variations due to inherent differences in painted and porcelain parts, as well

as differences caused by kitchen lighting, product location, or other similar factors. This cosmetic warranty specifically excludes any display, floor, “As Is”, or “B” stock appliances. UNDER THIS SPECIFIC WARRANTY, A PROOF OF PURCHASE (E.G., RECEIPT) IS REQUIRED. If proof of purchase cannot be provided, date of production plus three months will be used as the purchase date. You may be required to provide clear images (e.g., pictures of the Product and/or including the data tag showing model and serial number), but failure to do so will not diminish your warranty rights.
15.4Repair/replace as your exclusive remedy
During this warranty period, Bosch or one of its authorized service providers will repair your Product without charge to you (subject to certain limitations stated herein) under a valid warranty claim under the terms of the applicable warranty. Bosch will cover the cost of returning the Bosch Product to Bosch via ground shipping, and the original Product (removed parts and components) shall become the property of Bosch. CONSUMERS MUST USE THE SHIPPING TOTE OR SPECIAL PACKAGING INSTRUCTIONS PROVIDED BY BOSCH. This warranty does not cover for shipping damage or loss of product during shipping. If reasonable attempts to repair the Product have been made without success, then Bosch will replace your

STATEMENT OF LIMITED PRODUCT WARRANTYen-us

Product with a new or factory certified (i.e., refurbished) replacement (upgraded models may be available to you, in Bosch’s sole discretion, for an additional charge). Bosch may repair a part of the original Product with a factory certified (i.e., refurbished) part. You have the right to reject a replacement Product that materially differs from the original Product. Bosch’s sole liability and responsibility hereunder is to repair the Product under a valid warranty claim, using a Bosch technician or one of its authorized service providers during normal business hours. For safety and property damage concerns, Bosch highly recommends that you do not attempt to repair the Product yourself, or use a non-authorized service provider; Bosch will have no responsibility or liability for damage resulting from repairs or work performed by a non-authorized service provider. Authorized service providers are those persons or companies that have been specially trained on Bosch products, and who possess, in Bosch’s opinion, a superior reputation for customer service and technical ability (note that they are independent entities and are not agents, partners, affiliates or representatives of Bosch). Nevertheless, having your roduct serviced by a repair shop that is not affiliated with or an authorized dealer of Bosch will not void this warranty. Also, using third-party parts will not void this warranty.

15.5Out of warranty product

¡ Service calls to correct the installation of your Product, to instruct you how to use your Product, to replace house fuses, or correct house wiring.

¡ Damage or defects caused by labor or parts installed by any nonauthorized service provider, unless approved by Bosch before service is performed.
In no event shall Bosch have any liability or responsibility whatsoever for damage to surrounding property, including cabinetry, floors, ceilings, and other structures or objects around the Product. Also excluded from this warranty are Products, on which the serial numbers have been altered, defaced, or removed; any type of service to teach you how to use the Product, or servicing where there is nothing wrong with the Product; correction of installation problems (you are solely responsible for any structure and setting for the Product, including all electrical, or other connecting facilities, for proper foundation/flooring, and for any alterations including without limitation cabinetry, walls, floors, shelving, etc.); and resetting of breakers or fuses. TO THE EXTENT ALLOWED BY LAW, THIS WARRANTY SETS OUT YOUR EXCLUSIVE REMEDIES WITH RESPECT TO PRODUCT, WHETHER THE CLAIM ARISES IN CONTRACT OR TORT (INCLUDING STRICT LIABILITY, OR NEGLIGENCE) OR OTHERWISE. THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED. ANY WARRANTY IMPLIED BY LAW, WHETHER FOR MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, OR OTHERWISE, SHALL BE EFFECTIVE ONLY FOR THE PERIOD THAT THIS

STATEMENT OF LIMITED PRODUCT WARRANTYen-us

EXPRESS LIMITED WARRANTY IS EFFECTIVE.

SOME STATES DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, AND SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED WARRANTY LASTS, SO THE ABOVE EXCLUSIONS OR LIMITATIONS MAY NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM STATE TO STATE. No attempt to alter, modify or amend this warranty shall be effective unless authorized in writing by an officer of BSH.
