LG WD 14440TDS Washer: Persistent Spin Program Hang & Drum Arrangement Issue

Hello, I saved the washing machine from scrapping LG DD WD 14440TDS, the problem is that, for example, I choose the spin program without rinsing, e.g. 1000 revolutions shows the time of 12 minutes. She turns the drum to arrange the load and begins to spin, slowly spinning to medium speed, then slows down and again as if she was trying to arrange the laundry, and arranges it constantly and "hangs" and time does not pass.

However, after turning off and on from the beginning of the same program, it does not even start to screw, only endlessly as if it tried to arrange and it freezes again. The pump turns on, sometimes it is quieter and louder, it is probably flown out, but it probably does not stop it from freezing. I tried empty and with some load, it looks a bit like in other washing machines as if there was a problem with the tacho.

I also have a similar LG DD washing machine, so I can replace something, I will add that sometimes when the drum is idling, it screams a little, but if it screwed in slightly, it does not, the bearing has no noticeable play, where to start looking?

I will add that I dealt with the repair of washing machines and I have already repaired a dozen thanks to this forum, without even creating a new topic or asking myself any questions, so I can do it, but LG DD is a bit new.

Have you checked if you can pump out the water without any problems? In my old Amica, contamination accumulates notoriously at the filter. I have a very small bathroom so removing the filter requires emptying the bathroom. Dishwasher tablets turned out to be quite an effective method. None of the manufacturers recommends it, but I decided that I had nothing to lose, 1 tablet a month is enough and something will always come off. There are also special tablets for washing machines, but they are weaker than dishwasher tablets. Sometimes it was able to work without a problem, other times when it was spinning (whether it was in the washing process or just spinning). If you want, try to put 1 tablet (any brand) at about 60 * C and a long wash. Pay attention to whether the washing machine makes any disturbing sounds during washing.

I did not wash with this washing machine, because if I do not want to spin, the laundry will not end either, the filter is clean, the pump looks like it is just flown out, and it should not affect, first let it spin normally, then it can run the laundry.

Try to do what I wrote earlier, here a lot depends on the quality of water and contamination of clothes, detergents used. Because if it's an electrical or mechanical fault, this tablet won't do you any good, if you have easy access to the filter, you can clean it yourself and try again. If the washing machine has water, spinning will not start, and you will not drain the water when your filter is blocked.

This washing machine does not contain any water, it is dry.

Are you sure that the pump is worn, not blocked, and hence the difference in comfort?

When the washing machine is "drained" of water, the condition of the pump does not matter, it may not even work.
My friend talbotsolara , to check the cleanliness of the hydrostatic impulse chamber, or if you have a donor, it is worth trying to replace the drum wheel positioner (after removing the drive wheel at the bottom, there is a positioner on the coils, probably 5 wires come to it).

And what brush motor? What condition of the brushes? As for the pump, it can work louder when dry. You also need to check the hydrostat, the patency of the hose, the patency of the lower cup, i.e. connecting the pump to the washing unit itself. It may also be that the hydrostat is jammed and does not give a signal that the washing assembly is empty of water and thus, consequently, there will be no spinning. Too short brushes also prevent spinning and may damage the rotor in the motor. Good luck, because if you do not detect anything in these operations, then you will have to take care of the control panel and the module, and there will be more work and more precise work. Let me know about the results of these reviews, then someone else will probably drop off something more. You do not know the washing machine (the point is that you were not its user), you need to review everything from the very beginning, including drainage patency.

I have just disassembled the pump unit (there are two), one pours water probably back into the powder hopper and one traditionally poured out of the washing machine, the pouring one is obviously more flushed, but both work. As for brushes, they are missing because it is a brushless motor on the drum. The cup and hose are free, the pressure switch I do not know how to check because it is stepless, it seems to me that it is something like a potentiometer that deflects the pressure from the cup, I will immediately replace the second washing machine if they are the same. I was already getting to the positioner, but I haven't pulled it out yet. I changed the hydrostat and the same thing, something is spinning for a moment and 15 minutes. only 2 minutes elapses. Is this drum whining at idle speed probably a bearing? The drum seems to resonate.

The bearing will be heard when you turn the drum with your hand when the washing machine is turned off, and when the positioner is damaged, the drive makes interesting sounds too ...

Since you have already checked a few things, it may be worth checking the heater for breakdown to ground, preferably with an inductor.

I will check with the meter has a range of 40M?.

So it can be ruled out because the results are okay.

The meter is up to 40Mohm;] I wrote wrong.

I replaced the entire drive and then the same. Together with a strange noise, I think I give up because a wheel with magnets fell down, and when two pieces broke off, sticking it on will not do anything, right? Because it seems that then the poles are formed there?

If you cut a bar magnet (any other magnet will do the same), you will get 2 smaller ones in half, neither of them will have only the North or only the negative pole. The cut lines will be opposite to those you have at the "primary" ends of a large magnet.

In short, is it sticking together or not?

I have just been struggling with the LG washing machine for three days. Model WD 14352 FD, although it does not matter because the pumps are the same or very similar in all LG and maybe other brands. Symptoms similar to the first post. It usually blocked around 10-12 minutes, i.e. before spinning, or 23-25 minutes, i.e. before pre-spinning. I tried switching between programs. Sometimes she went, sometimes she didn't. If not, it became as above again. Finally, I took the water pump assembly apart. And all clear. A hole has been punched in the impeller cover through which the pump impeller axis passes and sludge has entered the housing, which can often be seen in the filter. It was he who caused the pump to freeze. Quick clean, a little oil inside and the washing machine did a few washes without a hitch. Of course, this is an ad hoc repair only to verify the correctness of the diagnosis. Inexpensive item and goes to replace.
