The water is not hot
When the smart toilet lid does not heat up, you can check the remote control, water temperature sensor, water tank heating tube, thermal fuse, and computer board of the toilet lid one by one. First check whether the remote control temperature is set to normal temperature, wait for 10 minutes after setting the temperature, if it is still not hot, unplug the water tank heating wire and measure whether the resistance at both ends and the heating tube is normal (the normal value is about 92Ω) If the thermal fuse is damaged, continue to measure whether the resistance at both ends of the temperature sensor is normal (25KΩ—80KΩ). If the above is normal, the computer board is damaged. For example, if the water tank is changed, check whether it is normal after replacement. If the water is always heating The computer board is damaged and needs to be replaced together.
The seat ring is not heated
In this regard, check whether the remote control, seat ring heating wire, temperature sensor, computer board and connectors are damaged one by one. Use the remote control to set the heating state. If it is not heated after 10 minutes, unplug the heating wire of the seat ring and measure whether the resistance value at both ends is about 960+/-50Ω. 5K—15KΩ is normal), and whether the connectors are in good contact. If all are normal, the computer board is damaged. If you change the seat ring, check whether it is normal after the replacement. If the seat ring keeps heating, the computer board must be replaced together if the computer board is broken.
The wind is not hot
Check the drying device and the computer board, and measure whether the resistance of the two ends of the drying heating wireframe is 89＋/－4Ω. If there is no resistance, the drying device is broken. If so, press the dry button after being seated correctly to measure the two ends of the heating wireframe socket Whether the voltage is 220V, if there is no voltage, the computer board will be broken. If you change the drying device, check the computer board carefully. If the motor slots are short-circuited, sometimes the heating wireframe will open due to increased load and slower speed, which may also cause damage to the computer board.
The above are the common failure causes and solutions for the smart toilet lid not heating. The replacement parts are highly professional, and it is recommended to ask professionals for repairs.
