Noise
：
Under normal operation the system will hum due to the motor, impeller and cooling fan in operation.
Grinding noise
：
The stainless steel skirt is loose. Push the stainless skirt up into the guide groove and turn to the right until you hear a click. With the skirt secure, the noise will
go away. There also might be the chance the stirring shaft was inadvertently bent. If this is the case, unscrew the bottom pump disk and gently push the impeller
until it is centered.
Slurping noise
：
Your pump has formed a water vortex like when you are emptying out a bathroom sink or tub. Add more water or gently disturb water with a spoon. There
is no sure way to eliminate a vortex from forming due to the pump rotation but usually will go away on its own.
Gu Woosh noise
：
The pump is sucking air - add more water. You should also see small bubbles in your tank.
Food damage
：
The pump’s water jet is cracking eggs or damaging fish fillets: Turn the pump outlet to face the container wall; this will greatly temper the flow of the pump
output. It is also good practice to bag eggs to prevent them from being “blown” around in certain containers.
