Other Troubleshooting
No waterflow / “E3” Error: Press [Mode - second button] to restart water circulation cycle;
Check to ensure Chiller Hoses are connected properly and Tub Fitting Valves are in the open
(parallel) position; Check Water Filter condition- replace if discolored; Check to ensure Water
Inlet and Outlet fittings are not blocked.
Hose Connections Leaking: Check to ensure gasket is in place; Disconnect and reconnect
Chiller Hose, ensuring snug hand tight connection; Replace Hose O-Ring with new one.
Tub Deflates Immediately After Inflating: When inflating, ensure that the Inflation Valve Pin
is in the depressed (out) position prior to hooking up the Inflation Hose; if unsuccessful, Tub
Inflation Valve may be damaged and require replacement.
Tub Deflates Over Time: Temperature change may cause air pressure in Tub to change
slightly, re-inflate accordingly; If deflation continues regularly, an air leak may be present. Air
leaks can be found by using soapy water to locate the leak, and then the included repair kit
can be used to prevent further leaking.
Chiller Will Not Turn On: Ensure Chiller is plugged into an active power source; Check Chiller
Power Plug GFCI has not tripped by cycling Power Switch Off and then On. Test GFCI
functionality by pressing the “Test” button, and reset to On position. Press the Power On
button on the Control Panel to turn on the Chiller.
Water Is Dripping From Chiller: During heating mode, condensation may develop inside the
Chiller unit in certain high humidity conditions. A small amount of water drainage from the
Chiller is normal in this circumstance; Check Hose Connections are secure and that they are
tight and have O-Rings in place; Check Water Filter Housing connection and that it is tight and
has the Filter Housing O-Ring in place; Check Drain Plug Cap is in place and tight.
When Temperature Set Point is Increased, Chiller Does Not Stop Running: If changing
from a low set point to a higher one, or vice versa, the Chiller will switch from Cooling mode
to Heating mode to reach the new set point. The Chiller will also cool or heat to a
temperature just beyond the set point to ensure the Chiller does not cycle on and off
excessively, and will restart automatically when the water temperature gets outside of the set
range by a few degrees Fahrenheit.
Water Has Become Cloudy - Check filter element and replace if discolored;
Add 60cc (2oz) of Oxidizer to water to break down organics and allow to run
for 2 hours; Replace water if all above fail
Tub Is Difficult to Get Into Bag - It is important that the Tub be fully
deflated before folding. This is done by deflating with the Double Action Hand
Pump with Inflation Hose on the “Deflate” side. Ensure Tub is folded correctly
per Takedown instructions.
Cannot Connect Chiller to WiFi - Ensure that the WiFi network you are
trying to access is 2.4ghz. This product only works with a 2.4ghz wireless
network. Some networks can be configured to provide both frequencies if
they are dual-band; Ensure WiFi password is correct by testing with another
device; Ensure Chiller is in-range of WiFi signal; Ensure device with Tuya
Smart app has internet connection.
Error Code: E1/FL/FU - Too much air inside the water circulating loop.
Double check the Chiller Hoses, Hose Connectors, External Water Strainer, and
Water Filter Housing to see if any connections are not properly made. Review
Water Circulation Troubleshooting above for more detailed steps to resolve.
Error Code: E2/HH - Water temperature is too high.
Wait for the water temperature to cool down and then select “Mode” (second
button) to cancel this error code.
Error Code: E3/FU - Water flow is low.
See Water Circulation Troubleshooting instructions above for detailed steps
to resolve.
