It took in water for a rinse, got partly there and then pumped it out
again.


My Indesit does this - it is deliberate to rinse out the pump chamber.

Thats not true of a machine that is designed to be easy
to repair. Most of the repairs should be at the minimum
cost and thats well below the price of a new machine.

It's not necessarily the cost of spares nor the time taken to fit them
that is the cost driver for calling in someone to perform the repair.

It is with something designed to be easy to repair on the time.

How much does it cost to call out a plumber to change a 10p tap washer?

Washers arent repaired by plumbers.

So they turn up charge you £60+ and leave without fixing the washer then.

You never could bull**** your way out of a wet paper bag.

from the Wikipedia article and

lighter mass than a heavier one.

No it doesn't!

Ok ...

If the system is a long way off resonance both before
and after adding the mass it may reduce the amplitude of vibration,

Ok, so it's damping it ...

not the energy being transferred to the system.

So?

So this may or may not
be an advantage; probably not, because it does not alter the applied
excitation force which is presumably not amenable to reduction. But the
practical problem does not generally arise unless the original system
can resonate at the excitation frequency, and the use of mass in this
case is lower the resonant frequency which does reduce the energy stored
to near that being provided by the excitation force, rather than
building up increased oscillation due to stored energy - which is
problem requiring a solution in the first place.

Ok?


Fair enough if people want to include that under the concept of damping,
but it is a different thing from power dissipating damping.

Who was defining the damping process being used?

If you stick a mass to the middle of a panel likely to 'drum' or
'resonate', you are damping the (broad spectrum) vibrations of said
panel using no more than increased mass.

Damping and therefore dampers do not need to be a complex mechanical
device.

So you don’t get what can be filthy stagnant water
mixed in with the first fill used for the first rinse.

I thought the purpose of the drum weights was to reduce the amplitude of
vibration (in conjunction with the springs) whilst maintaining a balance
between drum movement and whole machine movement (which of course would
happen if you had a solid coupling).

that they went to double sided boards with the exact same track

one thing very right though, they used a bunch of small PCBs instead
of one main one. MAde them way more repairable.

no idea, never saw their production lines. All I can say is it was crazy-bad on set after set.

Maybe to be replaced soon with a tank full of water. This could make

Its been done before, its not as good as its much less dense than concrete.

The expensive machines use cast iron or brexiteers as they are very dense.

If you're a remainer, then you must be the exception to the rule.
