5. After using the Turbo wash function, if the water pressure is weak when using the posterior/feminine function;
It may be because the Turbo wash function operates at the lowest pressure setting regardless of the set pressure level (to avoid discomfort in the area). Therefore, please reset the water pressure when reusing the posterior/feminine function.
The posterior/feminine/turbo wash function is not working.
Problems may arise under the following circumstances:

(Turn counterclockwise to fully open the valve.)
2-2. Remove the pressure reduction valve for flushing.
(Pressure reduction valve removal guide)
3. If water is being used elsewhere simultaneously:
Our bidet operates directly from the customer's water pressure. When water is being used elsewhere (washing machine, sink, shower), it may result in reduced water pressure, affecting drainage.
4. If the original water pressure is low:
Check the water pressure at your home.
(If the pressure is less than 1.5kgf/㎠, drainage may not be efficient.)
(To confirm the minimum required water pressure: Open the water supply valve fully and collect water in a container for 10 seconds, then check the quantity (3.5 liters).)
5. If a dual valve is installed:
Remove the dual valve and use our bidet's water supply hose.
How to clean the nozzle
The nozzle cleaning method is as follows:
External Nozzle Cleaning (Manual):
Press the nozzle cleaning button on the remote control or control bar to extend the nozzle.
Clean the exposed nozzle with a brush.
After cleaning, press the nozzle cleaning button again to retract the nozzle.
