Release time:

Check if the drainage valve core is stuck in a power-off state. You can see if the valve core rod is in place; otherwise, the internal spring may be stuck. At this time, the valve cover should be unscrewed to check for foreign objects that may be stuck or damaged, and repairs or replacements should be made.
If the drainage valve is normal, check if the traction rod of the puller is in place. Pulling and retracting the traction rod by hand should be flexible. If there is a sticking phenomenon, it indicates that the internal puller is damaged and should be repaired or replaced.
If the puller is normal, check if the puller has also moved when powered on in the water intake state. Shake the drainage valve core to drain; this indicates that the computer board program is disordered and the computer board should be replaced.
