The repair methods for common faults of smart toilets are as follows:
Water is not hot: Check the controller, thermal fuse, water temperature sensor, water tank heating tube, computer version.
First, check whether the temperature setting of the controller is at room temperature. After sitting down, wait for 10 minutes, if there is no heat, unplug the measurement tank plus the resistance on both sides of the ** is about 92 ohms, and then measure whether there is a resistance of 92 ohms on both sides of the heating tube. If not, it means that the fuse wire is broken. If the tests are normal, it means that the computer board is broken and needs to be repaired or replaced with a new one.
Seat temperature is not heated:
Check the controller, PC version, seat heating wire, temperature sensor, connectors.
Use the remote control to set the heating state and sit for 10 minutes, if there is no normal heating, unplug the seat ring and add **, measure the resistance on both sides 960+ -50 ohms up and down, if it is not reached, the heating wire is open, if the resistance value on both sides of the measurement temperature sensor (5k 15k) is normal, you need to check whether the connector is in good contact. If it's normal, the computer board is broken. If the seat is replaced, check whether it is normal after replacement. If the seat is always heated, the PC version should be replaced together.
The indicator light is on but not working:
Check the remote control, drain motor, hall plate.
First check whether the remote control is turned on for automatic water discharge, and observe whether the status indicator lights up after opening, if it is set or cannot automatically discharge water, you need to detect whether the motor and hall plate are faulty.
Does not automatically drain water:
Check the stepper motor, optocoupler board, and PC version.
a.The stepper motor rotates all the way and the optocoupler plug is unplugged. If it stops rotating, the optocoupler board is damaged or damp, and if it is still rotating, the computer board is damaged.
b.The stepper motor does not rotate, and the resistance value of the unplug of the stepper motor 1 and other wires should be about 30 ohms. If it is normal, then it depends on whether the secondary pole of the multimeter transformer has AC 9V output, if it is normal, it is the computer board is damaged.
