Sometimes, an air pocket develops in the pump or a wire becomes loose in shipping. In this case, it sounds like an air pocket as it makes a loud sound. If it was a hum or no sound, then a wire probably came loose.
Please let machine cool down for 4 hours. Upon depressing the power switch, quickly elevate and lower the reservoir 1" up and down repeatedly until you hear a different noise. Do not perform for more than a minute. If this does not work, please email us your invoice number and phone number so we can call you to resolve. You will also need a turkey baster with water so the air pocket can be forced out.
