When the nozzle is stuck and cannot be fully extended, press the flush button or self-cleaning button on the control panel, forcibly pull out the nozzle by hand, then turn off the power supply of the toilet cover, brush out the extended nozzle with a toothbrush, and then push and pull the nozzle back and forth until it is smooth.

Finally, turn on the power supply of the toilet cover, turn on the flush or self-cleaning button, and determine whether the nozzle can extend normally. When the nozzle cannot be fully extended, contact after-sales or professional maintenance personnel for maintenance.
