Adding extra water to GE Harmony HE top loader PTWN8050M
From what I can tell after a bit of research, the LG Wave (WT5101H) and GE Harmony (PTWN8050M) are the exact same machine. The only functional difference I can see after comparing them carefully is that the LG Wave allows for adding extra water to the wash cycle, while there is no obvious way to do this on the Harmony unit. I have read older posts where people mention if they pause/add a garment and then restart on their Harmony models, the machine adds more water. Others with older Harmony machines say they can use a preset that uses more water by default and then change the agitation level to suit the load.
I have tried calling a local shop that sells GE as well as GE themselves and no one was able to provide me with an answer as to whether these things are true for the newer machines. I assume neither person I spoke with had used the machine, and it was not on a spec sheet. So frustrating.
Could someone with the newest model GE Harmony top loader (PTWN8055M) PLEASE confirm for me whether either of these is true, or if there exists a 'work around' to add more water to the wash cycle with any combination of agitation and spin options?
Also, if there are any other functional differences I have missed between the two machines, I would be happy for someone to point them out to me.
Are the Kenmore Elite (29272) and Samsung VRT PowerFoam (WA5471AB) also manufactured by LG? I have not compared those in detail. I would appreciate if someone in the know could tell me what other current top loaders with heaters are basically this same LG machine. I am trying to find the best similar option for features, price, part availability and service.
Thank you all for your help!
