All Echo Water® Machines and Qi Devices™ come with a warranty. If a replacement product is issued for any reason, the warranty continues from the original date of purchase. It does not restart.

All warranties are valid for the original purchaser only. The warranty covers defective parts, labor, and return shipping of the product to the customer. The cost of the shipping from the customer to Synergy Science™ is the responsibility of the customer (unless otherwise stated below). If the defective part(s) cannot be repaired or replaced, the purchase price paid for the machine will be put toward the price of a current, new, or refurbished machine.

Warranties do not cover improper use of the product, issues caused by a lack of basic maintenance (including timely filter changes and preventive cleaning with the Echo Cleaning Cartridge), any damage caused by misuse or abuse to the product or improper wiring in the home, acts of God (including storms, flooding, fire, electrical damage from power surges, power spikes, lightning, etc.), and any physical damage to the product by the owner.
