Sorry to break the news to ya but... it's not always the engineering department that's to blame. I was an intern at Whirlpool's German R&D department (where the first Duets were made) and the engineers told me they wouldn't buy the newest washers they had to designed themselves because of the low water usage that the marketing department wanted to see. Engineers rarely get to design what they want to - they get orders from marketing to make machines use less water, spin faster, run quicker, have a larger capacity etc. and for a manufacturing costs, of course. What you end up with is machines like the LGs that use plasic parts where metal would have been a much better choice. Sadly, many machines and homes had to be damaged before metal brackets were used and more shock absorbers were added. |

The first video shows what appears to be a single large/bulky item in the crashed machine (which there's no way to know if they'd already remove some other items). I think user error is definitely a contributing factor -- washing such items as comforters and waterproof/resistant mattress pads on the Normal/Regular cycle with maximum spin speed instead of using the designated Bulky Items cycle which has a slower speed and may take specific actions to help balance and deal with such items. However, machine design and software is also a factor. Presumably there is no physical off-balance sensor switch. Off-balance is detected via software monitoring drum rotation and inertia during an initial spin ramp-up phase. The sensing algorithms drop-out after satisfactory balance is confirmed. Balance can be thrown wildly askew if for example a waterproof item shifts and releases retained water as spin goes along at a very high RPM, and there is no bump sensor to deal with the situation (for example, by quickly braking the basket). Which, however, does go back to user error because the situation wouldn't be so damaging at a lower RPM. My Fisher & Paykel machines have the same type of tub suspension (hanging rods and springs), and neither of them has had any problem with it (one is 15 years old). The IWL12 model has a specific Comforter cycle that runs two deep rinses with no spin between, and then pauses before the final spin and beeps for attention with a message on the screen to "Press Item Down Below Medium/High Water Level and Press Start" to continue. This is to insure that a large billowy item isn't protruding out of the tub which could cause damage to either the machine or the item during spin ... and also gives the user opportunity to visually observe that the item is arranged evenly around the basket, although spin is at a slow 300 RPM. The other machine doesn't have a Comforter cycle but the user guide states to wash such items only on the Delicate cycle. I have re-spun such items at the full 1,010 RPM for additional extraction, but ONLY while attending the machine and having manually rearranged the item to insure good balance. |
