Was following another thread in the "Deluxe" forum about the decline of laundromats and was thinking about a video of an old commercial washer that I've run into on YouTube a while ago. It's a Troy Laundrite "Big Boy" front loader. Its operation is kind of peculiar, at least by the noise it makes.

When it reverse tumbles, the motor makes an ominous sound for a split second when it goes under load, almost like a shrill buzz. It's like it's audible enough to let you know it's reversing. When it spins, you'll hear a loud BANG!, too loud to be a relay. It almost sounds as if a clutch of some sort has engaged, I'm not sure. When it has fully spooled up, it sounds like a jet engine.

Pretty interesting washer that sounds ominous, more so than a larger Milnor or UniMac, those machines are quiet until spin. Never have encountered an Ametek/Troy machine, which is why I'm wondering about the way it works and why it makes the noise.

Here's the video:

The sound: likely a solenoid engaging for the transmission to shift into spin/

Or the Drain Solenoid. As I recall these machines just dumped water. No Drain pump. And the way the water cascades over the window port seems like it doesn't drain first.

Thanks for the vid. Brings back memories of the Buzzard"s Bay Speed Wash in the 1960s.

They had 4 of these. That Laundromat also had 20 Philco Bendix Doubles Loaders, 20 Top Load Speed Queen Solid Tubs (SS) 20 Huebch "LoadTrol Dryers, and 15 Hoyt Dryers with adjustable heat.

Ah, good point. I never guessed the clank was the drain solenoid. I just thought it had something to do with a clutch mechanism, if it even had one.

During the wash cycle, why does the motor buzz/grind/groan every time it reverses, and then suddenly runs quiet? It's particularly pronounced when it begins to rotate clockwise. I've never heard a machine do that before. Usually the motor is pretty silent until it is time to spin/extract.

the Norge Village we would go to had one of these.  It started spinning when still mostly full of water.  I don't ever remember a drain solenoid.  I just remember all the water falling all over the window.

I remember that very machine at the laundromat by my house when I was a kid. Spent many hours in there watching that machine and can still hear the noise!

It's been years since I heard that unique motor sound of a 40# Troy machine. I remember one at the laundromat here in PL and then it was taken out and replaced with a 50# Wascomat. The Wasco proved to be a much more refined and better cleaning and spinning machine. Of course it lacked the sounds and spin drama of the Troy but water did still cascade down the door and it spun up like a jet engine.
Here is a video link for reference.

Motor starting

Is what that sounds like to me. Induction motors started "across the line" typically do make loud magnetic sounds.

If the motor is started without load, it comes up to speed quickly enough that it isn't really noticeable.

But this one is starting against the load of the washer, with the weight of the wet clothes in it, each time.

These machines use a separate motor for spin and they start the spin while the drum is full of water to help distribute the tumbling load.

I also remember people putting too much detergent in and the suds would come pouring out of the dispenser above the door and flowing down to the floor.
