cleanguy,
The commercial homestyle units use the same outer tub (200511P) and inner tub (719P3) as the 2017 and prior residential units, thus they are the same capacity. The coin operated units are smaller.
Update on the transmission:
I did some more digging and the 2015 revision of the residential parts manual (203417) lists the same part number for the transmission in the residential and commercial unit (38165P). In the 2017 revision of the residential parts manual (203417R5) the part number for the transmission changed to 203768 so it is likely an updated part number and not a different transmission.
If you want to look at the parts manuals you can search google for the part manual part number. You can type "Alliance 203768" for example to look at the residential unit parts manual. The dates listed below are the revision date of the manual not the date of the machines that it covers.
Residential parts manual part numbers: 203430 (2015), 203430R5 (2018)
Residential parts manual part numbers: 203768 (2015), 203768R5 (2017), 203768R8 (2018), 203768R9 (2018)
So with this new data all the parts between the 2017 residential unit and the 2018+ commercial homestyle units are the same except the electronic control panel and front decorative cover.[this post was last edited: 4/19/2019-19:40]
