No observable diff as such.
No stiffness in the clothes?
Not much. Quite the contrary, increasing the quantity leads to sudsing. I am still trying to figure what is the right quantity for my regular load. The sudsing isn't visible during wash cycle, but it becomes apparent during rinse cycle. Even the drain water despite 3 rinses, machine still has some sudsing left baffles me. As a last step, I am forced to run a rinse cycle so that the machine and the drum is rid of the residue.
Hard water is harder to wash with but should be easier to rinse the detergent out than soft water. So you will see more suds with soft water than with hard water. I'm surprised with the hardness you have that you see much suds at all
Amount of detergent I've said to start with half a scoop for a full load. Don't go less than that or the clothes will not be cleaned properly.
How full are your loads? a smaller load could foam up more with that amount of detergent than a full load. If you overload then detergent won't be able to mix properly.
Thicker items like towels are going to suds more than thinner fabrics with any detergent.
If suds are too much then maybe the detergent isn't dissolving properly.
Is that because the water temperature is too low that residue is being left or the water is too hard? you tell me
You can try mixing it in some warm water (not hot) and then pouring it into the detergent drawer. This will decide if the problem is of dissolving or not.
A second way is to add the detergent directly into the drum instead of the drawer and then add the clothes.
Report back on what difference either method makes.
If it still suds in the third rinse with both these methods then try Surf for front loader powder. Change the detergent.
Henko may not be suitable for your water conditions. I can't remember if Henko just suds up more than other detergents. Meaning they cheaped out on anti-foaming agents.
It has something called Aqua detergent which I read throws water out but retains detergent to get the maximum from the detergent.
What you're referring to is this Ball valve tech. What does it do? Ball valve allows interrupting the cycle to add extra laundry. Hence, lets the water out while keeping the detergent in. Confusing until you realise 'add item' is the only use case when you want to drain the water out but not the detergent.
The device lets you pause the cycle, open the door and add laundry during the wash cycle. This technology prevents wastage and enhances the wash. So any machine that has the 'add item' feature has similar tech like this. A machine without the 'add item' feature like my LG does not have it.
This has nothing to do with leaving foam behind as you think. The machine is not responsible for the excess suds.
Already did that. It's mentioned in my LG FL thread. Even attached sticky rubber pads which LG provides to attach to the machine's leg if placed in bathroom. So that the machine won't lose on the grip. Yet, it moved. Maybe it depends on power transfer. Gradual versus smooth.
You
said it only happened when you washed one item and the problem went away after you got the service guy to look at it.
Maybe your machine has since moved and needs another levelling
