Ringer just goes around instead of backwards an forwards so clothes get tangeled around agitator

That does not sound good. New dogs sound great, but you must get to the bottom of why the clothes are becoming twisted on the agitator. Usually not enough WATER. Think loose flow of clothes submerged.
Long story short, you cannot jam pack this machine. Less clothes, more water, will equal long life.
Be sure that the mating teeth for the dogs, is not damaged. Slipping here would make loud noise.
More water, less clothes.

check to see if your machine is in buttonhole mode, one of the legs of the buttonholer will always be a reverse zigzag.

It should sew from the front to back so, from your description, it sounds as if it is working correctly. Perhaps you could explain more clearly if this is not the solution

When loading the machine, load towels, sheets or jeans with an accordion fold instead of putting the laundry in a circle around the agitator. It helps to put the clothes in at the twelve o'clock position, then six o'clock, then nine o'clock and then three o'clock. Repeat this sequence until the washer is full.
The laundry can circulate much better and get cleaner too.

sounds like a screw may have become missing to keep the reverse knob in its proper position so it is backwards inside the machine

Try leveling the washer... If the washer is level, then don't wrap the clothes around the agitator...drop the clothes straight in, on top of each other evenly around the agitator. The Ensignia washer has a Dual action agitator... That means the clothes roll over them selves, instead of moving side to side, as with a traditional agitator. wrapping the clothes around the agitator will cause the load to be un balanced and then cause the "banging" noise... this should take care of the problem...

Hi,
If this a whirlpool brand washer, there are sone parts bad in the agitator it's self. These parts are called dogs and they make the agitator rachet so that the top half only goes one direction. Does this sound like what you are experiencing? If so, let me know and I can assist you further.

Thanks
Vic

Click on Menu on the base
click on the forward >> or backward << keys until it says the day of the week
click on set/ringer soft key
use forward >> or backward << to adjust the time and AM/PM
when you are done either click menu or wait and it automatically goes back to normal.

If you have made no changes to the vacuum's setup and are using it on same carpet you have previously used it on with no problem, then the most likely cause is the agitator/beater bar's drive belt is worn or on some models may have a tension adjustment which is set too loosely. This can also be caused by having the vacuums height adjustment set to low for the carpet or flooring you are using it on, causing to much drag when the vacuum is pulled backwards for the agitator to overcome.

The vast majority of agitators turn in a forward direction, as if it would pull the vacuum forward, when you pull the vacuum backwards the drag is increased.

So...First check height adjustment (a no cost fix), then check out the tension adjustment (if present on you model, some engage when top of vacuum is tilted back after stepping on the release pedal) Lastly, consider changing belt especially if you have had the vacuum awhile or if it gets a fair amount of use or it you seem to need to use it on a low height setting all the time to vacuum up debris.

Hope this helps!
