Is the water supply turned fully on?
If the water supply is not fully opened, or turned all the way on it could cause a whooshing noise.
Is the drain cap on correctly?
The drain cap needs to fit securely onto the water pan to produce optimal ice. If the drain cap is loose; thin ice, no ice production or whooshing sounds may occur.
To check the drain cap:
Unscrew the drain cap from the bottom of the water pan located inside the storage bin. Allow water to drain completely. Replace drain cap. See the illustration below.
