I lost my chance to get a pre-2018 speed queen, I haven't seen a used pre-2018 unit come up in my area, and I need a new washer. I was thinking about the possibility of getting a new Speed Queen homestyle commercial (LWN432SP115TW01) unit which still has a transmission and adding a water level selector switch. The 2017 commercial unit (LWN432SP113TW04) shares the same parts manual as the 2018 unit (LWN432SP115TW01) and it appears they just changed the pressure switch to a fixed pressure sensor. I want to make sure I am not missing something obvious or otherwise. Is it correct in thinking I could replace the pressure sensor in the 2018 unit with a pressure switch from the 2017 unit? I know I would have to drill a hole in the front panel and buy a knob etc.

I'd Email Speed Queen asking for a wiring diagram or service manual and see if its doable. But honestly, I would just do this:

You also lose that eco awful cycle.

Adding An Adjustable Water Level Control To A SQ Commercial

Top Load Washer, Hi Luke, yes what you want to do is easy, I would not contact SQ about the proposed change of WL switches. If any thing talk to the commercial distributor  you are buying the machine from, but I think you have it figured out already.

As long as he does not mention what he is going to do, I see no issue in contacting SQ. There was a member on here who was curious about the cycle times and Speed Queen sent him a tech only service manual.

The Commercial washer already has a wiring diagram inside the control panel.

True, but I'm not sure if the OP has purchased machine yet. Knowing ahead of time makes things easier. I used to do it all the time when Service Matters was open to the public, made purchasing machines ahead of time for mods a no brainier.

All really good points, I have not bought a commercial unit yet. I am still trying to weigh my options and am hoping a used speed queen comes up in the next few months before I get rid of the Samsung front loader that came with my house. Also I am not exactly sure where to buy a commercial unit except from a online store.

chetlaham,
Will that control panel plug right up to the existing connectors on a new unit? The control panel also does not have extra rinse, is that just a switch that is added or does the timer have to support it?

Extra Rinse

It is a timer function that is enabled by the switch.

Plugging in

chetlaham's profile picture
Honestly, I am not 100% sure if it will plug right in as I have never been in a commercial unit (yet), however the wiring is simple and splicing it to the new harness will not be difficult or complex if you only have basic wiring experience.


Regarding extra rinse the timer has to have that function built into it.

After some digging through the parts manual it seems you can also convert the 2018-2019 electronic homestyle commercial unit to the 2017 and before electronic unit with a new control panel and pressure switch. This change seems very tempting as I always wanted the AWNE92SP113TW01


Parts to convert manual timer commercial unit LWN432SP115TW01 (2018-2019 no water level switch) to LWN432SP113TW04 (pre 2018, has water level switch)
202937 - Pressure switch
203323 - Knob
203673W - Front panel, if you do not want to drill a hole in existing panel


Parts to convert elecontrinic homestyle commercial unit LWNE22SP115TW01 (2018-2019) to residential AWNE92SP113TW01 (pre 2018)
202769P - AWNE92SP113TW01 control panel with overlay
203843 ??OR?? 202470 - Pressure sensor
- The pressure sensor in the parts manual changed in the 203417 rev 9 parts manual, the rev 8 and before lists the pressure switch part number as 202470
