The most common failures of the dehydrator are 5:1 clothing being entangled in the dewatering bucket to entangle the shaft; 2 short circuit of the motor coil caused by water leakage and humidity; 3 bearing bushing rust; 4 capacitor failure or capacity drop; 5 brake spring brake disc Hold tight.

The most troublesome clothing problem is to unpack it and take it out. The fault of the capacitor has been ruled out. Then I will only talk about the remaining three situations.

First, open the brake tension spring and Dehydrator Motor let it off the brake disc to see if it can start smoothly and work normally. If you can, just stretch the spring to the brake disc forever (and of course it can be replaced). Just wait a while after the dehydration is complete to stop.

If the brakes are normal, use one hand to open the brakes. The other hand rotates the dewatering drum shaft. The resistance should be small at this time. If the resistance is large or large, it means that the copper bushing of the motor bearing is dry or rust-free. In this case, remove the motor, remove the rear cover, remove the rotor, and then clean and fill with the oil.

If the first few fault conditions do not exist, it is definitely a problem with the motor coil windings. Most of this fault is the phase-to-phase short circuit of the motor, so it is generally not easy to see on the surface. But in any case, you have to rewind the coil. But because the new motor is easy to buy and cheaper, most of them choose to replace it.


From what you said, I think the possibility of a motor short circuit is the greatest. So I suggest you buy a new one. The price is about 60 yuan.
