Appliances Neutral drain function in washing machines

AI Thread Summary
The discussion centers on the neutral drain function of Whirlpool/Kenmore direct drive washers, which is a phase where the washer pumps out water without spinning or agitating. The mechanism behind this function is not immediately clear, even after disassembling and reassembling the gear case. Observations indicate that the direction of the shaft's rotation changes between agitation and spinning, but the implementation of neutral draining remains elusive. Online resources suggest that pauses in motor rotation control the activation and deactivation of neutral draining, raising questions about how a mechanical device can respond so adaptively. The possibility of a centrifugal clutch being involved in this process is mentioned as a potential explanation.

TL;DR Summary
Is there a animation showing how the gear case in a Whirlpool/Kenmore direct drive washer implements neutral draining?
It would be interesting to me (but not essential) to see a visual explanation of how the gear case in a Whilepool/Kenmore direct drive washer implements the neutral drain function. The neutral drain function is a period of time when the washer is pumping out water but not spinning or agitating. I've disassembled and reassembled a Kenmore direct drive gear case guided by the detailed video

I can see (first hand) how changing the direction of rotation of the shaft switches from agitation to spinning. But I don't see how it implements neutral draining. Articles on the web say that a pause in the motor rotation activates and deactivates the neutral draining. It's hard to see how a purely mechanical device can react so flexibly to pauses.

Three rabbits will be wintering in a 2m x 2m x 2m wooden hut. Outside temperature does not go below -30c (-22f) Planning to put a 50cm by 50cm 1mm thick stainless steel sheet on the floor of the hut (inside off course) My plan is to heat the sheet with a 50w PTC heater element https://fi.rsdelivers.com/product/dbk-enclosures/fg135600/dbk-enclosures-heating-element-75mm-50-w-100-240-v/dc/2995922?backToResults=1 Is this heater (50W) enough to keep the pad warm enough to sustain liquid...
Hey all. I'm looking to buy a zero-turn mower and I need to build/purchase a ramp to get it into my shed for storage. Exact model is this one. I need to figure out how long of a ramp I need to make sure the mower doesn't bottom out when driving up and down the ramp. Mower stats: Wheelbase: approximately 76 inches. Height: 4.5 inches (based off the highest setting on the deck height adjustment) Shed entrance is 12 inches off the ground. The manufacturer says that the mower can handle...
Thread 'How to remove a seized toilet tank bolt?'
greetings I replaced my bedroom toilet due to water leak and unable to replace water tank bolt with new ones. so now i have old toilet in the yard and i took a closer look at the seized bolt, it seems that the bottom part (a butterfly fastener) holds onto the bolt really tight, when i turned the head inside the tank with flathead screwdriver, the fastener moves with the bolt as the whole. is there a way to remove the bolt?
