What do machine designers find so difficult about balancing the laundry before spinning?
My mum purchased a new Bosch which wouldn’t fit under the draining board, so she required a coverplate. Then it danced around on its spin cycle, so I bought the installation brackets to bolt it to the floor!
(And yes, the transit-bolts were removed; and the machine properly levelled and loaded with a 3/4 to full load!)
The way this Bosch moves about the floor reminds me of my previous AEG machine (even the spin-profile is similar).
Conversely, my current Zanussi IZ16s is extremely stable and never moves an inch.
I’ve noticed on the IZ16, that at the end of the final rinse, it gives a half-hearted spin for a matter of seconds. This to my mind, gets rid of the majority of the water, and seems to allow better distribution of laundry during the reverse-tumbling stage on the ramp up to spin. It results in a stable spin.
Why don’t all manufacturers program this into their machines?
(The floors are all suspended-type on joists. Obviously a stone/concrete floor is preferred for rigidity).
Re: Washing machine vibration on spin cycle.
Depends on the machine suspension, weight as well as the flooring so there’s a lot of variants involved in determining just how stable any machine will be on any floor other then concrete.
Almost every machine uses a staged spin like your Zanussi these days, only reaching full speed for the final few seconds in most cases.

After investigation it appears that the majority of Bosch machines have the usual pattern of four bolts securing drum. Then there is the odd model which has one either side about halfway up and then another one towards the top of the machine. It would appear that as this top bolt has a visible spring through it, customers are not always removing these as they feel it is there for a purpose. When adjusting feet, the locking nuts need to be wound up to the cabinet to prevent the feet from vibrating and possible causing machine to move on spin.
DonRe: Washing machine vibration on spin cycle.
Thanks for info.
I noticed with my mother’s Bosch that it seems to jump into a violent spin, accelerates over a few minutes, then decelerates to what I presume is a monitoring stage (drum does not stop, but continues revolving possibly @ 82rpm?). After 20-30 seconds it ramps into the final 5 minute spin phase. My old AEG performed a similar profile.
I was always under the impression from the AEG and Bosch brochures of the 1990’s, that the machines achieved spin profiles, interspersed with frequent tumbling stages (AEG’s “Variomatic Spin”; Bosch’s “Interval Spin”).
They do not seem to do this. Did they ever?
