"During the cold spray the Maytag in the video below slows down in spin only slightly toward the end of the 1 minute spray indicating terminal saturation is taking place toward the end of 1 minute and that the machine can handle a 1 minute cold spray with satisfaction."
Maytags are EXTREMELY sensitive to proper setups and adjustments when it comes to the spin cycle, spray rinse, being water logged, and suds locking. What appears like saturation or suds locking, in many ways, is improper adjustments and setups. This is why I always make a huge deal about it on threads. It all comes from personal experience and experimentations over the years. I custom adjust machine for peak performance.
Motor tracks are extremely clean, well lubed WITH THE PROPER LUBE (I experimented with other lubes and had disastrous effects, same with goes for the damper pads), rollers/glides in perfect condition, pulleys clean, motor pulley's not worn (transmission belt pulley), genuine belts, proper carriage springs that are not weak, pump bearings in perfect condition and lubed, pump belt custom adjusted for peak performance (ALWAYS adjusted looser than the 1/4" factory recommended setting!!!), standpipe cut down to the lowest factory height rated height if external and not built into the wall, cabinet perfectly level, suspension springs properly tensioned and tub perfectly centered (this takes a lot of time and experience to do right!), tub perfectly centered during installation with continuous testing until it's. If all of these things are in proper order, using a high drain pulley and belt combo does a great job with extreme situations like massive overuse of detergent and radically out of balance draining/pumping, especially during the spray rinse.
Now I show off a bit with my experience:
In the video you posted, notice how the tub leans down and to the right? Either the machine is NOT level or the suspension springs are NOT properly centered. If the machine is level, someone dicked around with the spring adjustments and they're not properly tensioned (they appear to be tensioned on the weak side, by my experience). If the tub shakes around unnecessarily, it causes water to build up and swirl between the tubs rather than drop straight down and be pumped out. It causes the tub to stall, making it appear to be suds locked.
Another huge red flag: Notice the tub is vibrating a bunch while getting up to speed and then starts dancing around in a circle beginning at 15:48? This is a clear indication the inner tub is badly off center. Again, this will cause the illusion of a suds lock problem when it's being water logged by swirling water between the tubs.
