That perplexed me too.

Unlike a tumble dryer, which can end up full of lint and dry clothes and
has a big heater plus a fan blowing the hot air around, a washing
machine is full of wet stuff. It's unlikely to cause a serious fire, and
indeed, according to the BBC, there have been none.

They always have a ridiculous number of models in production. Modes for
different retailers so that they can't be beaten on price, different
countries, etc.
Can this lead to them not being sufficiently focused on quality and
reliability. Too much distraction.

I thought door locks tended to be mechanical - locked by a bimetal device
with a heating element. Could that heater get too hot if in the proximity
of a tub of hot water?

TV news had a shot of the door lock mechanism (square hole for the door
latch to go through), showing a couple of wires going into it and burning of
the plastic next to one.

Suggested workaround is to wash at 20C, suggesting the heater element isn't
in circuit.

Perhaps they're putting the door lock in series with the heating element?

Looking at the interlocks on ebay, most of them have connectors rather than
wire-terminals. This is from one of the affected models:
http://siteassets.ransomspares.co.uk...6242617757.jpg

Googling for schematics (not that many are public) does suggest it's common
to put the door/lid switch in series with everything else, so the machine is
cut off when the door is open. Which would mean the door switch takes
substantial load on warm washes.

Although I can't quite work out how they're exploding. Heater is presumably
being jammed on leading to steam buildup. If the door switch fails short circuit,
that would prevent the machine stopping when the door is opened, but I can't
see how it would cause the heater to run for longer. Unless this is a
separate problem?

Door interlock interrupts power to, among other things, the main heating element. So if it has deteriorating contacts, it will burn.

I wonder if it's more insidious than that, IIIRC there's some Ecobollox
directive that says that appliances must not consume more than 0.5W
when "off". Ours does this via the main (wash selector) switch turning
off the SMPSU, maybe switching through the door switch is just a much
cheaper way of doing it? I notice the door switch referred to in the
pic claims to be rated at 16A...

I doubt it. All electrical equipment comes with fire risks obviously, and the standards were quite good, just not quite good enough. I doubt they knew anything was amiss. Whirlpoo does not have a rep for top quality, safety etc, and there is far worse in the marketplace.

The whole thing sounds like a fiasco of major proportions to me. I can only
guess that something in the construction of the door latch was not tested
for fireproofness if that is a word, as, like you say the way the system
works has been the same for many years. That is unless they re invented the
well worse again in 2014. I can see some kind of interlock based on a
circuit and a relay that fails connected, and hence overheats the relay, but
surely relays that are designed for such uses must be tested to comply?

I had a service suddenly catch fire some years ago, but it was not serious
and self extinguished. Caused through dry joints sparking on a pcb and the
lacquer used to protect it was what caught fire, but the pcb itself and
everything around it were fire retardant, so although it made a crackling
sound emitted a lot of pungent smoke it did not really do any damage to the
room it was in. Of course it could not really be repaired since the
original fault was mechanical which had overheated joints etc etc.
Sometimes you have to just say its ready for the scrap heap.

Whatever happened to the testing for flame retardation. When I worked fro a
company making tvs, all the critical components were tested by actually
trying to set one on fire and even pcbs had a push out rectangle you could
batch test with.
The most flammable bit of those tvs was the glue holding the veneer to the
chipboard cabinets. Yes it was that long ago. They also had to retain an
imploding CRT so chards of glass were not accelerated into the user!

Yes but the point is, the plastic parts used for such things tend to be very
well tested, as its an obvious safety critical part. If it melted, for
example and flooded the kitchen I doubt that would down well with customers
either.
Really, saying only use a cold wash is stupid, its either dangerous or its
not.
They have in effect layed themselves open for retailers to accept the old
ones back then take #whirlpool to court over their cock up.

Now they are not due to the EUSSR CE standards.
Now we have lots of electrical stuff made with highly flammable thermo-plastics.
Enables stuff to be made far more cheaply.

Portable appliances, consumer units sockets etc all burn nowadays whereas previously they didn't. They just went black and made a nasty smell.

The door interlocks, which I believe are the problem, are similar in
operation across many machines. I'm not defending Whirlpool- having had
issues with one of their fridge/freezers in the past (about 30 years
back so not the current round) I'm no fan of theirs, although they did
respond well after a complaint to their CEO BUT I'd not be surprised if
similar parts are used in other machines which haven't been identified
yet by other manufacturers*.

Also, in fairness to Whirlpool, the scale of this problem is massive.
Their logistic system simply isn't designed to cope with this scale of
refit etc.

People are, perhaps understandably, concerned after Grenfell etc, but
just how many incidents have there been across the units in operation?

*When you buy parts to repair appliances yourself, you often find they
are common to a number of machines which aren't simply 'badged' versions
of the same basic beast.

Which standards are you referring to?
My experience of designing to recent EU standards (which are mostly
now harmonised with USA and other national standards) is that there
is a great deal of attention to the prevention of fire and its containment
should it occur.
For example, anything close to a potential ignition source generally
needs to meet flammability standard ULV0 or equivalent. There is a lot
of detail about sizes of apertures in enclosures which might allow flames
or molten burning plastics to escape.
Reputable test labs will, if they consider it necessary, follow the paper
trail for the materials used. In one instance a PCB insulating spacer
was made in China and had no markings because it was just a bare board.
Intertek required us to provide documentation from the Chinese board
manufacturer about the source and certification of the resin used to
manufacture the PCB before accepting its flammability rating.

Under the CRA15, the retailer has the option of carrying out a repair,
which of course is exactly what Whirlpool is offering to do.

I had assumed steam buildup was a cause, but maybe just a side effect?

It seems this is what comes of excessive value-engineering, and then so
commoditising the machines that there's no support network to modify them
after-sales. Their standard business model just assumes you'll buy another
one when it breaks, which doesn't work so well for recalls...

Does anyone know what the actual mode of faliure is?

Rather than "Whirlpool recall", I suggest "Forget Whirlpool".

Given the liability of retailers, I wonder if any are having to consider totally dropping their brands because they cannot afford the public liability insurance demands if they continue to sell them?

Adblock has detected 158 ads on that link.

So? How do you expect free-to-access on-line newspapers to pay for themselves?

They should include only just enough adverts to cover the production
costs, not as much as they think they can get away with.

And avoid nuisance ads that cover the text; videos that start playing
(whether the sound is turned on or not); using *all* the processor
cycles in the complicated bidding system they use to decide which ads to
serve up.

They're just greedy.

Under the CRA15, the retailer has the option of carrying out a repair,
which of course is exactly what Whirlpool is offering to do.

Except that Whirlpool are not allowing others to repair affected appliances, and a consumer would have a good argument that a repair contravening the manufacturer's instructions was not a satisfactory remedy in law.
