Interesting units. They use a 3 phase AC motor as the 'transmission'. its only a belt driven tub off a bi-directional motor so they dont need a complicated agitator transmission. Also the AC motor has a tach output that obviously monitors speed, ie it can be set to 5 different spin rates, off low med high and max. Now MAX is an interesting speed as the drum looks like its spinning at about 1600 RPM and the drum wheel in the back is about 12" wide while the motors drive is about 1" so that means the drum is being driven 1:12. so 12x1600 is 19200 motor RPM! Thats humming! These washers have fully suspended drums and even shock absorbers and weigh about 200 lbs to stay on the grount when they are spinning an out of balance load. "Delicate fabrics are not recommended to spin at max spin rates or damage can occur". Alsso the locking mechanism for the door is pretty slick. It used a "Wax motor" as a servo to move a fork past the nub on the door striker so you cannot open the door unless it mechanically releases. You may be asking what a was motor is? When you look at the door lock mechanism, all I saw was a small box that had a resistor symbol stamped on it. I thought it was a heater of some sort but did not realize what a heater would be doing on a lock mechanism. Turns out it uses the same principle as a cars thermostat: a wax pellet in a confined space will expand 5-15% when heated and contract same amount when cooled so you couple this to a sliding mechanism you get a VERY strong servo (up to 900 lbs) that operates slowly and controlled. That is why the lock takes a few seconds to release. I got a NICE matching stacker set for $200 and the guy said the washer doesn't spin and the dryer makes a noise. $200? You got a deal! I picked them up, took em home and turned them on. The dryer just had a squeaky bearing that I lubed and it quieted down. The washer had a few issues but nothing that cost me any money: the belt had come off the drive wheel somehow. Put it back on and didn't see any reason why it came off. It started to rotate the drum after that and I though I was in the clear. I ran the thing through a short cycle and water came gushing out the back right corner, WTF> I pulled the top off and found a rat had chewed a 1/2 hole in the rubber discharge hose elbow.

I was able to cut the elbow under the hole and then clamp the remaining stub to the plastic nipple, nothing but a pipe clamp! Ran the cycle again and the "door open" light came on and shut the cycle down. after I took the locking mechanism out (and found the "wax motor"), I pulled the switch apart and found the gushing water got the 2 contacts in the switch wet or shorted the leads or something but as soon as I dried them out, shot some WD in there and put them back into service, I got no more false "door open" triggers. So all in all, I feel I got a pretty good deal. I dont think the guy was aware of the rat chew as nothing in the cabinet had any rust on it. Probably happened during storage as the drum smelled pretty musty. Oh and a final warning: parts for these are $$$! The lock mechanism is $120 alone while the front door gasket is over $200! But they do use 1/3 the water, take 20% longer to wash and some say don't clean that well at all. But they do look nice.......with towels on top. Rockauto "International Scout" magnet came with it....Guy owned a $90K Hummer.
