New LG front load washer: just one rinse?

[johnmk]

Thank you for your thoughts, nmassman44.

The machine empties the wash water, spins, and then as it's filling up with rinse water, it does spray it over the clothes all throughout. That's all part of one rinse, though -- one fill of water. If you listen closely to the sound you can tell when water's being drained, when water's being filled, etc. That helps to clarify things.

A single fill of water is just a single rinse. How can rinse be defined any differently? Does each tumble constitute a new rinse? Then there might be hundreds of rinses, by that definition. But that definition would be absurd.

 

[johnmk]

To clarify even further, there are only two drain cycles. One after the wash, and one after the rinse.

There is a spray rinse kicking in at 18:00. It works just like the spray rinse in a top loader, I'd say - spray fresh water over the clothes and drain it out simultaneously.

 

[johnmk]

I believe it's only draining out the rest of the wash water, and at the highest spin speed the water just ends up flying every which way, especially that water that exits the drum at the top, and which gets spread out quite flat by the massive centrifugal forces, and has no other way to go except out in every direction.

I've been there during this process, and there's no fresh/clean water entering at that time.

I wanted to add to this on a couple of experiences.

I hsve owned an lg washer & it was my favourite to date, it had a recirculatory jet which was very powerful & hit the back of the drum, I wouldn't discount the effectiveness of the recirculatory jets, they enable an effective rinse at low levels.

Combining the high spin and fresh water spray before the deep rinse with the jets, it might not be rinsing that bad.

I accidentally found my Dyson washing machine does something similar when you select the dirt only soil setting, the load size recommended is a half load, the machine spins at max spin (1400rpm) after the main wash followed by a very high level rinse and then a 7 minute final spin at 1400rpm. The result was surprising good, luckily though I can add up to 5 rinses.

Hi Darren,

Thank you for your sharing your experience. The recirculating jets are a fantastic concept, no doubt about it. However, I don't understand how recirculating soapy water provides an appropriate level of rinsing within one rinse, using one fill of water.

 

[logixx]

It sprays fresh water through the clothes as they spin - once before and twice after the deep rinse with softener - and immediately drains the water out of the tub during thses spray rinses. It only recirculates water during the main wash and the deep rinse.

Here we go

Taken from the (rather useless and uninformative) service manual for the WM8000.

There are a four hoses in the first picture going from the water valves to the dispenser and one hose to the front of the washer - which supplies FRESH water for the spray rinses. In the second pic, you can see where the hose disappears behind the counterweight to then connect to the spray rinse nozzle in the rubber gasket.

Thank you Alex!

I would love to have access to that service manual for the WM8000, as I suspect my 3470 is similar to it in many respects. Can you hook me up? Even better would be the WM3470 service manual, but I think you would have referenced that one, if you'd had it.

 

[logixx]

The service manual has no information on cycles or even water temps in it at all - worthless. It just contains a table that lists the cycles and options like the user's manual does.

I found it on a page called electrotanya, IIRC. Try this name plus wm8000 service manual in Google. If you can't find it, I'll give you the link tomorrow.

 

[johnmk]

I found it, thank you for the information. You're quite right, it is not too helpful here. Also found the service manual for the WM3470, but I fear these service manuals we've been looking at are for the simple repairman, and it's nothing like a technical manual w/ highly detailed specifications.

There might be info in there that is pertinent to the rinsing situation, I'm not sure I understand it, but in any case my experience is that the rinse cycle only makes one single request for fresh water in the default cottons/normal cycle.

 

[logixx]

There are four (4) requests for fresh water after the suds have been spun from the load.

Well, you can contact LG and see if they're willing to send you a cycle overview. I have seen these overviews before and they are not that comprehensive. They used to be included in the service manual.

 

[logixx]

This is what one of these cycle overviews looks like. This one is from a long-discontinued model's (WM3885) service manual. And in the video, a lady talks of a - as she calls it - cheat-sheet.
