Hello there everyone,
I just wanted to give everyone a slight update on this thread. I purchased a LWN432SP115TW01 a few months ago and I came across this thread when i was on the hunt for how to add a water level switch. I read through the whole thread and decided to go through with the mod/addition suggested by LukeS. However, after reading through and studying the parts manual and noting the differences between the two models, i did end up getting a few more parts so that i didn't have to cut and splice wires or bypass anything like in the previous posts. I am, in no means, a repair technician. I am pretty handy and i just wanted to make sure i did this the right way and maybe my OCD got the best of me. If someone here would like to correct me or anything i might have missed (or misunderstood), please do!
Here is a list of the parts i used to get it to be a true(er) LWN432SP113TW04:
202937 - Pressure switch (the one the knob attaches to that selects load size)
203323 - Knob (attaches to above switch through the front panel)
203673W - Front panel (if you do not want to drill a hole in existing panel)
203428 - Wiring Harness (so that you don't have to cut or splice wires together)
B12548401 - Pressure switch (yes, another one) - This is what the two blue wires are supposed to attach to
203511 - 8" PVC Tubing
203464 - Barbed Tee
Don't get me wrong here. This is going to cost an extra 70-80 bucks going my route. If everything for everyone who posted above is working fine, feel free to go with the short list of parts and save money, if that's what you want. I just had an aversion to cutting wires and then splicing the two blue together; It made me wonder what they went to. And hell, i still don't understand why there are 2 pressure switches and what the 2nd one is actually for. All i know is that the LWN432SP113TW04 has 2 of them and if you don't splice the blue wires together or plug it into switch #2, then the Heavy Duty/Perm Press portion of the timer will not work.
A benefit to going this route is that you can revert all of it and go back to stock if one of these pressure switches goes out at some point. That way you can still wash clothes while you're waiting for the new part to arrive. Simply swap the harness and put the old pressure switch and front panel back in.
Anyways, a few notes here if anyone is wanting to go the route i went.
Wiring Harness - The 113TW04 Harness exactly the same as the 115TW01 Harness, except the 113TW04 has separate plugs for each of the pressure switches instead of one long plug for the single pressure switch. Everything else is the same and plug and play into the 115TW01.
Pressure switch #2 - as i stated above, i don't really have a clue what it does or how significant it is. In the parts manual, it's labeled as Pressure Switch, that's it. On the parts website (i used PWS Laundry), it's labeled as SWITCH, PRESSURE WTR 1 LEVEL (300/255). This part fits directly into the spot where the 115TW01 Original pressure switch was. Clip is included to pop right in. No adjusting or modding needed.
PVC Tubing and Barbed Tee - I knew i didnt NEED to buy the OEM tubing and Tee, but they were so cheap so why the hell not? The 8" PVC tubing is attached to Pressure Switch # 2. The other end of the 8" PVC tubing goes into the right side of the barbed tee. I then cut some of the excess tubing (maybe 5 inches) from the original washer tubing to connect the bottom of the tee to Pressure Switch #1. Whats left of the original washer tubing then connects to the left side of the tee.
I am a knuckle head and didn't take photos of how it turned out, but i will gladly go take the panel off and do so if someone here isn't understanding what i did or is just curious to see it. Over all, it was a super easy swap. All you need is a flat head screwdriver and a standard (not metric) socket set. The exterior screws are 1/4" socket and the ground screws are 1 or 2 sizes bigger (can't remember, sorry).
Take care everyone! Please feel free to ask me any questions or point out any mistakes i may have made. Again, i am not a technician, just pretty handy and patient enough to go through the parts manual.
