Common faults and solutions of smart toilets (1)

Smart toilets have entered thousands of households, bringing comfortable improvements to our bathroom cleaning, followed by failures of smart toilets of various brands, which affect our mood of use. Today, let's take a look at the mommon faults and solutions of smart toilets.

First understand the basic composition of smart toilets. Smart toilets generally have the following 15 components:

1. Computer board

2.Water tank device

3. Cleaning device

4.Drying device

5. Supercharging device

6. Water release device

7. Remote control device

8. Deodorization device

9. Flip device

10. Solenoid valve device

11. Transformer

12. LED display

13. Music installation

14. Seat washer

15. Infrared device

Common faults of smart toilets and how to judge and troubleshoot:

1. No response

Fault inspection direction: power socket, leakage protection plug, power button, installation strip contact, first pole of transformer, panel, control panel

Troubleshooting method: whether the power socket is powered, see if the reset button of the leakage protection plug is pressed, whether the indicator light is displayed, wheter the power supply of the whole machine is pressed, the upper cover is displayed, and the installation strip is in good contact. Whether there is a 7V output panel on the secondary pole of the transformer, and whether it is short-circuited by water. If all the above are normal, the control board will be bad.

2. The water is not hot(other functions are normal)

Fault checking direction:

Remote control, water tank heating pipe, water temperature sensor, thermal fuse, control board

Troubleshooting method:

Whether the remote control temperature setting is at room temperature or not and wait for 10 minutes. If there is no heat, please unplug and measure the resistance at both ends of the heating line of the water tank is about 92 ohms, and then measure whether there is a resistance of about 92 ohms at both ends of the heating pipe. If not ,the fuse will be bad. Measure the temperature The resistance value(25k~80k) at both ends of the temperature sensor is normal, if it is normal, the control board will be broken. If the water tank is replaced, check whether it is normal after replacement. Ifthe water keeps heating, the control panel is bad.

3. The seat cushion is not heated (others are normal)

Fault checking direction:

Romote control, seat heating wire, temperature sensor, computer board, connector

Troubleshooting method:

There is a remote control to set the heating state (sit for 10 minutes). If there is no heating, please unplug the seat heating wire and measure the resistance value at both ends to be about 960+/50 ohms. If there is no open circuit of the heating wire, if the resistance value (5k~15k) at both ends of the temperature sensor is nromal, if the connector is in good contact, if it is normal ,the computer board will be broken. If the seat ring is replaced, check wheter it is normal after replacement. If the seat ring keeps heating, the control board will be replaced together.

4. The air temperature is not hot (others are normal)

Troubleshooting direction, drying unit, contorl panel

Troubleshooting method:

Measure whether the resisance at both ends of the drying heating wire frame is required by the regulations. If not, the drying device will be damaged. if so, after confirming the normal seating, press the dry button to measure whether there is 220V voltage at both ends of the heating wire frame socket. If ther is no voltage, the control board will be damaged. If the drying unit is replaced, the control panel should be carefully inspected.

NOTE: if a short circuit between motor slots sometimes slows down due to increased lod, causing the heating wire frame to open, it can also cause the control board to burn. Replace control board and drying unit.

5. Deodorization does not start(others are normal)

Fault inspection direction: deodorizing fan, control panel

Troubleshooting method:

After confirming the correst seating, use a multimeter DC20V to measure the 12V voltage at the socket of the deodorizing fan. If the fan is bad, if not the control board is bad
