Troubleshooting
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.
Gurgling + 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.
System will not turn on:
Check power plug and breakers.
Low water level alarm:
Add more water – the water level can be dropped during operation by the pump due to the water
turbulence.
Low water level alarm turns on after a few seconds of operation：
Add more water – The pump generates "waves" – sometimes these waves will cause the water level
at the sensors to fluctuate up and down. The waves sometimes drop the water level right under the
sensor and will cause a low water alarm. This is normal and you just need to add more water.
Temperature read does not match thermometer:
Sous Vide circulators are calibrated to a scientific platinum primary standard which is far more
accurate than store thermometers.
Lights in house are slightly flickering when system is on:
This is normal as the circulator is modulating power.
