The drainage speed is slow

Analysis and maintenance: This fault is generally caused by the drainage valve is not fully opened or the drainage pipe is not smooth. The specific reasons and treatment methods are:

(1) There is debris blocked in the drainage valve or the drainage hose is bent and deformed. Just remove the debris in the drainage valve or replace the drainage hose to solve the problem.

(2) The gap between the drainage rod and the rubber valve becomes larger, as long as the gap between the drainage rod and the rubber valve is appropriately adjusted.

(3) The internal spring of the drainage valve is too long or loses elasticity. Just replace the inner spring.

(4) The drainage solenoid valve moving core damping is too large or the suction becomes small. Remove the corroded dirt in the electromagnet or replace the drainage solenoid valve.
