Good morning, Maple.
The first thing you should do is remove the belt between both pulleys that involve the main engine and the transmission case.
Then, and while the washing machine is in an upright position and with the back cover of the cabinet removed from its place, program the washing machine only with water at its lowest level to confirm that when taking only the washing stage, the pulley of that main motor turn both ways alternately. If it does, it is ruled out that the failure was the product of
* .- that the capacitor was deteriorated and replacing it would suffice;
* .- that the triac related to the direction of rotation that is not carried out is damaged and must be replaced on the programming card;
* .- that one of the cables involved with the main engine is broken and must be repaired;
Another possibility would involve the clutch area in the transmission case. For example:
* .- That the internal spring is having problems presenting some deformation in it.
* .- That the belt is subtly loose and skate between both pulleys. Look to see if that is the case.
* .- That the splines of the impeller or horizontal agitator are partially worn. Replacing the impeller would suffice if that were the case.
It would be necessary to review which of the above possibilities is the reason for the failure to which you mention.
Thanks and regards.

Maple approach:
Okay. Another thing I said that the engine tries to turn but something stops the internal spring that leads to any position or has its side

Greetings Maple. Then I leave you an image of how the spring of a guide inserted inside the plastic gear goes:

There is a hole a few millimeters at one end of the plastic gear as illustrated in the image where the spring guide fits and must remain there to prevent the spring from moving on its own axis without control . This hole is oriented towards the pulley of the transmission case while at the other end of the spring it is the one that is coupled to the final part of the transmission case housing.
In the same way I leave you the exploded view that corresponds to a Daewoo brand washing machine which has a transmission box based on the same design of the brand you have:
http://i.imgur.com/7Bpo1B5.png
It should be noted that any deformation by lower case that is present in the spring of a guide will suffice to cause certain irregularities in the correct operation in the area of the clutch. In the same way I leave an exaggerated image of a spring of a guide that is not appropriate for use due to deformation and presence of rust
http://i.imgur.com/3Aurr6c.png
Sometimes the spring of a guide undergoes a deformation at the level of a pair of its turns where the final part of the housing of the transmission case is in contact with the steel cylinder. These two pieces sometimes act as a clamp by hooking at least one of the turns of a guide spring when there is enough space for the loop to enter that place. The damage will be magnified if the spring of a guide is not replaced in time, to the point that the turn will break.
Now, if at the moment when the main motor rotor seeks to make the rotation counterclockwise and that is when you perceive that it is slowed down, what you should do is subtly adjust the clutch arm with the help of the adjustable screw located there.

There is also the possibility that the clutch arm would somehow deform from the way it came from the factory due to some forced labor or manipulation by someone who possibly modified its original position. Fortunately, if the clutch arm is metallic, it can be modified to solve the fault presented. Which will be impossible for the transmission boxes whose clutch arm is made of plastic.
To make sure that the fault is actually located in the clutch area due to some physical modification there, you can do the following test:
* .- Remove the plastic gear with the spring of a clutch area guide only and then program the washing stage only with water and with the water level either at the low level or at the medium level. The test should result in the impeller or agitator rotating alternately as the main motor rotor does without appreciating the fault you pose. If the same fault arises in these conditions, the problem would be in the main engine. However, and in general, the fault you raise is due to an abnormality in the clutch area as the clutch arm tooth is not positioned correctly between both teeth in the plastic gear. The aforementioned tooth of the clutch arm should not be very outward nor completely towards the end where two teeth of the gear make contact.
You should even confirm that the tooth of the clutch arm fits perfectly between both teeth of the plastic gear. If the clutch arm tooth enters diagonally between two gear teeth instead of parallel, there would be a possible error in the deformation of the clutch arm structure because the tooth depends on the clutch arm.
Pay close attention to those details to solve the fault you pose. Then comment on the results achieved.
Thanks and regards.

Greetings Maple.
My apologies for the information you provide on 02-08-2019. All this information is based on a transmission box design different from that of the glasses washing machine to which you mention. I decided not to delete that information that may be useful for the Phiclco, Ranser, Daewoo, Samsung, Lg, Atma brands for example.
Another possibility that the rotation can only be done in one direction can be the product of the 2 spring ears being in a single gear of the two that are present there
The following link illustrates the 2-ear spring that is inserted into the end of the clutch arm:
http://i.imgur.com/eLT63DU.png
The following link illustrates the same two-ear spring located above the transmission case pulley
http://i.imgur.com/4rmilVX.png
The following link illustrates exactly where the two-ear spring is placed:
http://i.imgur.com/PhRHIkk.jpg
And this link illustrates both plastic gears - one on top of the other - and where one of the ears of the spring goes in the lower gear while the other ear of the same spring is placed in the upper gear. If both ears are in a single gear - be the upper one or the lower one - it will result in the rotation being made in only one direction in the washing and rinsing stages respectively.

The other possibility would be the internal spring - very different from the spring of the two ears - that if there is a defect, it influences it. By replacing it by buying the kit that includes the new spring and the other parts that go there, the problem could be resolved.
You verified the capacitor. You can replace it respecting the values indicated in its legend when buying it. There have been cases where the current signal travels in one direction only due to internal damage to the capacitor and therefore the rotation is only carried out in one direction instead of both directions in the washing and rinsing stages.
Thanks and regards.
