    Flushing Issue

    Excessive water splashes during flushing

    The flushing may not operate properly under the following condition:

    1. If the water pressure in the bathroom is high:
    Please adjust the water pressure using the valve connected to the bidet's water supply hose.
    (Turn clockwise to adjust the water pressure.)

    (TCB-090SA, TCB-9100WA, TCB-9100GA, TCB-8200SAW, TCB-8200SAB, PB-707S)

    Flushing does not work

    The flushing may not operate properly under the following conditions:

    1. If the toilet bowl is clogged:
    Press the jet button on the manual flush button to check if the toilet bowl is clogged.
    (If clogged, there will be no water flow, only bubbles.)

    2. If the water pressure in the bathroom is low:
    2-1. Adjust the water pressure using the valve connected to the bidet's water supply hose.
    (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 often should the filter be replaced?

    The replacement cycle for the circular HEPA filter is one year, and for the cypress wood filter, it is two years.
    After turning on the power, the filter remaining indicator will display the remaining duration before the circular HEPA filter needs replacement for 5 seconds.

    (M-001W, M-001B, M-002W, M-002B, M-002R, M-003W, M-003B, M-003R)

    The shape of the cypress wood filter is changing.

    Our cypress wood filters are crafted from solid wood, which may exhibit scratches, dents, and knots.

    Wood naturally expands in the summer as it absorbs moisture and contracts in the winter as it releases moisture. Over time, this process may result in size variations of up to 5mm or the occurrence of cracks in the wood.

    Flushing Issue

    Excessive water splashes during flushing

    The flushing may not operate properly under the following condition:

    1. If the water pressure in the bathroom is high:
    Please adjust the water pressure using the valve connected to the bidet's water supply hose.
    (Turn clockwise to adjust the water pressure.)

    (TCB-090SA, TCB-9100WA, TCB-9100GA, TCB-8200SAW, TCB-8200SAB, PB-707S)

    Flushing does not work

    The flushing may not operate properly under the following conditions:

    1. If the toilet bowl is clogged:
    Press the jet button on the manual flush button to check if the toilet bowl is clogged.
    (If clogged, there will be no water flow, only bubbles.)

    2. If the water pressure in the bathroom is low:
    2-1. Adjust the water pressure using the valve connected to the bidet's water supply hose.
    (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.

    The shape of the cypress wood filter is changing.

    Our cypress wood filters are crafted from solid wood, which may exhibit scratches, dents, and knots.

    Wood naturally expands in the summer as it absorbs moisture and contracts in the winter as it releases moisture. Over time, this process may result in size variations of up to 1-2 mm or the occurrence of cracks in the wood.

    3. If the air purifier was previously used in the kitchen or a smoking area:
