Troubleshooting
Noise:
A quiet electronic hum is normal
and when impeller and unit motor
are operating.
Grinding noise:
The stainless steel Skirt is loose.
Push the stainless steel Skirt up
into the guide groove and turn
to the right until you hear a click.
With the Skirt secure, the noise
should cease. In addition, the
stirring shaft might have been
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 it
will usually go away on its own.
Gurgling & wooshing 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 sh llets:
Turn the pump outlet to face the
container wall; this will greatly
temper the ow 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 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 uctuate 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 scientic platinum
primary standard, which is
far more accurate than store
thermometers.
Lights in house are slightly
ickering when system is on:
This is normal as the circulator is
modulating power.
