Speed Queen Washer LWN432SP115TW01 Overfilling

[GremlinsAtWork]

I have a brand new Speed Queen washer LWN432SP115TW01 that is overfilling. On both the wash and rinse cycle the tub will fill and stop. The machine will run (agitate) for a couple of minutes and then stop and start filling again till the tub is overflowing.

Everything I find talks about the tub overfilling on the initial fill. This one doesn't. As stated before, it will stop filling, run for a few minutes, and then start filling again to overflowing.

Thanks in advance for any guidance.

Sounds like the pressure switch (water level switch) may be at fault. Once it starts refilling, does it ever start agitating again as it is refilling? Is it siphoning water out of the drain hose as it is filling? 

Make sure the drain hose isn't shoved too far down the drain pipe in the wall (if that is your set up) or is laying down on the ground. What you don't want is to have the end of the drain hose too low because the water in the tub can siphon out of the machine as fast as it is filling and it will just keep trying to fill the tub. Also, check to make sure the rubber air hose that pushes on to the pressure switch is tight, at both ends. Make sure the plastic air dome at the the other end of the air hose (bottom left rear of outer tub) is clear and not clogged up with any gunk.  

If all that checks ok, then probably a bad pressure switch. Not a real common problem but there's not much else that will trigger the machine to stop and refill.

Close to the bottom where it 90s into the tub , it’s back had shipping damage , but that wasn’t apparent till I ran it in the shop . I always run ones with shipping damage  one cycle just to be safe

I've had a few where the black rubber grommet seal got rolled a over a bit causing a water leak but never had a cracked one. I'll keep an eye out for that in the future. Thanks!

i have never been confident in how the air dome fits into that , BUT seldom have any issues

I know. It seems like it would be more problematic but after several decades of the same set up, I've never had one leak other than the few that got rolled over during manufacturing. And those three were in the same 1-2 month date range so I think it must have been the same person on the line who installed it. That was about a year ago - haven't seen it since.
