Old vs new, which is best?

Having repaired more than 100 Kenwood Chefs, I compare newish and older machines. Which is best?

IMG_2724

Believe it or not, people do ask me which is best:  New or old machines?

There is of course, no right or wrong answer and the answer will vary, depending on the product and application.

But since the question comes up from time-to-time, I thought I’d give my opinion on the matter and have a bit of fun with the subject, a kind of shoot-out if you will.

My illustration focuses on an old favourite of mine; the Kenwood Chef.  My chosen opponents are a model from the early 1980s, the ubiquitous A901 Chef, made in England, and the much later 2000s KMC010 Chef, made in China.

The Chef is a good example for the shoot-out as the machine’s purpose hasn’t changed since it’s introduction to kitchens in the 1950s.  Many Chef accessories produced over the years are interchangeable, owning to the foresight of good design.

Some people think that new machines are best and more capable while other people think older machines are best as they were built to last. Since I’ve dismantled, used and admired 100s of these machines, here’s my take.

Round 1 – Performance

Older Chefs are less powerful than newer machines.  For example, the A901 has a 450W motor, whereas the later KMC010 has a much more powerful 1400W motor.  This means than the newer machine will be more capable to mix more stodgy mixtures for longer.  Counter-intuitively, the more powerful machine may be more efficient for some loads, compared to the lower power one, although I’ve never measured this.

A901 – 0   KMC010 – 1

Round 2 – Noise (from the machine)

Kenwood has tended to favour evolution rather than revolution with their product progression.  Many models available over the years appeared not to change much on the surface, but under the skin, small tweaks and improvements were taking place.  So, in general, the newer the machine, the quieter they tend to be.  There are some model variant exceptions to this, but the KMC010 is much quieter than my own good condition A901.

A901 – 0   KMC010 – 2

Oh dear, new things might be better after all..?

Round 3 – Durability

Now this is where things get interesting.  Many of the machines I receive in my workshop for repair are getting on a bit. Some of them are over 40 years old.  The machines have served their families well with faithful service.

Faulty older machines can often be turned around within a few hours in the workshop, to be back with the customer, to make more cakes.  The A901 Chef is a tough old beast.  The materials and finish rarely give any problems and major components rarely fail it seems.

KMC010 Chefs (and all newer models) that I see in the workshop are obviously much younger than the A901s.  While very capable and powerful, sadly, they seem to have failed, often only with occasional light use.

Seemingly, it’s true what they say, the older machines were built to last and I base that purely on customer enquiries and items I see to repair every week.  The newer machines often have features and buttons that don’t serve any real advantage, but have associated circuits which can and do go wrong, rendering the whole machine useless, if they fail.

A901 – 1   KMC010 – 2

Round 4 – Repairability

Now obviously, I am ‘repairability-biased’, this is a blog about repair after all.  However, the facts speak for themselves.  Older Chefs can be repaired with basic tools, reasonably priced components and a little know-how.

Newer Chefs, like the KMC010 are more complicated and have less user-serviceable parts.  This makes otherwise serviceable machines far more likely to end up in the scrapyard with seemingly minor faults, that were too hard to diagnose and repair.  The A901 wins hands down in the repairability stakes.

A901 – 2   KMC010 – 2

The feeling is tense and there’s an air of excitement as I get to call the decider on this slightly odd dual.

Round 5 – Value for money (the decider)

A new KMC010 Titanium costs over £600 today and it should be said that all Chefs are great machines and a worthy addition to any kitchen.  However, a decent second-hand Chef from the 1960s to the early 1990s is a worthy contender for a tenth of the cost.

Have a look on eBay and you’ll see A701s, A701a, A901, A901E, KM200 model Chefs, starting at £40, often with many accessories.  They’re just as useful and capable to serve most home needs.  Indeed, I have a customer who uses her standard A901 in an industrial kitchen, every day, with no problems.

A901 – 3   KMC010 -2

The non-scientific conclusion…

  • Buy an older machine and take satisfaction that it will last generations, can be easily repaired and work with most accessories available now.  Buying an older machine is probably less environmentally damaging than the manufacture of a new machine.
  • Buy a new machine and take satisfaction with additional performance and a manufacturers’ guarantee for the first year…

You know which machine I would buy…

Time to put the kettle on.

Nilfisk GM80 industrial vacuum cleaner

This ‘vacuum beast’ from the 1960s gets serviced, ready for today

Sometimes big is best and when it comes to longevity, this machine is tough to beat.

I wasn’t born when this machine was made, but good quality designs and engineering foresight, means that new parts fit retrospectively.  Why aren’t all machines made this way?

Make and model: Nilfisk GM80 (large)

Fault reported: Poor running

Cost of replacement: £600-800 (approx.)

Manufacturer support:  8/10

Cost of parts: £14.94, inc. carriage

Hours spent on repair: 1.5 hours

Tools needed: Screwdrivers, test meter, soap and water etc

Sundry items: Silicone spray, WD-40, cleaning materials, wire wool

Repair difficulty: 3/10

Cups of coffee:  X1

Biscuits: X2 Chocolate Hobnobs (that don’t dunk that well in coffee, truth be told)

Recently, I got the opportunity to tackle an industrial vacuum cleaner in need of a proper service, which had been in continual use since the late 1960’s.  Judging by the condition it was in when I first received it in the workshop, I doubt that some parts of the machine had received any care since its first day at work.

The machine in question is a Nilfisk GM80 (large).  It’s a ‘large’ as it has a milk-churn sized base to it, which means it can swallow a lot of dust.  The large base has long been discontinued, but you can still buy the current smaller base, should yours be damaged.  Indeed, the Nilfisk GM80 range of vacuum cleaners are all quite modular and feature different levels of filtration, depending on the specific environment they are put to use in.  This means you can easily swap parts from donor machines to keep older machines going. The design means that parts seldom go obsolete, new parts just get improved and fit older models.  Great news for sustainability.

Back to the machine in question.  It had been covered for many years under a service contract, but for whatever reason, that company were no longer taking quite as much time as they should and applying as much care with each inspection.  This ‘serviced’ machine had recently had a new motor (hence later model motor housing) but the basics of vacuum principles had been overlooked.

I won’t go into the repair blow-by-blow, so here’s a summary of the work completed:

  • clean of all rubber seals and mating surfaces, essential to avoid air leaks
  • check and adjust all housing clips and adjust as necessary (all of them in this case)
  • wash motor diffuser (this had been changed within the last year)
  • wash main cotton filter (this had never been done, it was so clogged)
  • wash motor intake filter
  • check condition of motor brushes and bearing end-float (all fine)
  • check and tighten electrical IEC connection
  • inspect flex for damage (all OK)

The previous service agent had stated that the damaged hose (original 1960’s rubber item) was now unavailable and that a replacement was impossible.  Impossible eh?  That’s two letters too long.

Upon taking the old hose connectors apart (and removing layers of gaffer tape), I discovered that the internal diameter was similar to a Nilfisk-to-Numatic aftermarket adaptor and with a little adjustment, this 1960’s Nilfisk machine could be made compatible with Numatic’s vacuum cleaner hose design, which is much more abundant, here in the UK.  So, with a little jiggery pokery, this machine is ready to work for its living, once again, with a shiny new hose.

So yet again, when an ‘expert’ tells you that something cannot be repaired, don’t necessarily take their word for it.  A second opinion can sometimes save you time and money.

The repair didn’t break the bank either and I have since taken on more machine service work for this organisation.
