Another smoking Kenwood Chef A901E sorted in time for Christmas…just

Another Kenwood Chef gets the treatment in the Workshop

How about another Kenwood Chef story?  I know I’ve covered this machine a few times now, but I’ll try and make it as interesting as I can.  I just LOVE Kenwood Chefs.

FixItWorkshop, December’18, Worthing, Kenwood Chef A901E on the bench.

A customer got in touch with me via the FixItWorkshop ‘contact us’ link asking if I could fix his family’s much beloved Chef.  While last in-use, it started smoking and smelling terminal.  How could I refuse.  I’m located in Worthing, but the customer was based in North London, quite a distance for a repair and would have been usually cost prohibitive using the Royal Mail.  However, using local drop-off points, carriers such as Hermes and DPD offer (slightly slower) courier services for about £7.00 one way, which starts to make more fiscal sense.  This is what we did.

I wish I’d taken a photo of the box the Chef came in, because the customer had clearly gone to a lot of effort to make sure it was well protected!

On with the repair.

The Chef has been in production many years and although they can often appear similar on the outside, they do vary on the inside, depending on the year of manufacture as small tweaks and improvements are made.  Evolution, rather than revolution, usually the backbone of any successful design.

The A901E is different from the previous A901 as it features an electronic speed controller, rather than a centrifugal affair.  While the later design is an improvement, it wouldn’t deter me from buying an earlier model; the improvement is small.

The A901E still features similar components to previous models which can and do fail, especially with age.  The subject here is about 30 years old, give or take.

FixItWorkshop, December’18, Worthing, A901E, motor removed.

The motor on the A901E comes out quite easily; first remove the motor cover, remove the mains cable (disconnect first of course), remove the top cover, belt, then the four screws holding the motor in.  The motor then pulls down from inside, out through the gap left by the hinge.  Easy.

The motor circuit board showed traces of component catastrophe with dust and dirt left by exploding components.  Nasty.  Pre-empting the fault, I ordered a repair kit before I’d taken the machine apart, together with replacement feet as the ones on this machine were knackered.  The kit includes capacitors, resistor and triac as these are the main components that tend to fail.

These kits are available on eBay and are worth the money as they are often cheaper than buying the components separately and they contain instructions for newbies.  Here’s a little slide show showing the process.

With the kit fitted, the motor re-installed, mains reconnected, the Chef ran well again, this time without burning or smoking.  However, all was not well as the speed control was a bit wobbly at lower speeds, which was just plain wrong.  Having worked on a good few Chefs, this problem is usually down to excess end-float on the motor spindle.  Working with the motor still in situ, the motor fan, which controls end-float could be adjusted with an Allen key.  Sorted.

Just the replacement feet to fit and after a quick clean-up, the Chef was reassembled, ready to go home.

A top tip for you.  If you intend to replace the feet on your machine and you probably should if they are old as they go hard or fall apart, then soak the area around the feet recesses with WD-40 or similar a day or so before as this will make getting the remnants of the old feet out, much easier.

Cost of a replacement:  £400 up.  Cost of repair:  £12.65 plus my time and tea.

Kenwood Chef A901 -a fishy story!

If your Kenwood Chef A901 starts to smell of burning, don’t despair, it can usually be saved.

I had an enquiry via this site from a fisherman who was very upset that his trusty Kenwood Chef A901 had given up the ghost.  Rather than using the Chef to make Victoria sponges, it had been used to prepare fishing bait.  It just demonstrates how versatile these machines are.

FixItWorkshop, Oct’17, Kenwood Chef A901 with motor speed control fault.

Whilst it was in use, the owner witnessed a bang then the smell of burning before the machine came to a halt.  The plug was quickly pulled!

Whilst discussing the fault on the phone, I suspected that the fault was probably due to the failure of the motor speed control circuitry, which is known to fail with age.  I had carried out similar repairs to other machines, including my own (in this blog) so agreed to take a look.

I received the machine quickly and upon inspection, the machine had obviously been cared for and considering its age, was in good condition.  The smell of burned-out components was clear, lifting it out of the box.

Dismantling the machine and removing the motor on the A901 is fairly straightforward, providing you allow time and make notes on where things go.  The components that need to be replaced are very accessible and anyone with moderate soldering skills would be OK with this task.

Luckily, the Chef is very well supported by long-term aftermarket suppliers and I bought an off-the-shelf spares kit at £14.10 delivered, from KAParts (www.kaparts.co.uk) via eBay, featuring upgraded components.  This kit is a little dearer, but component technology has moved on since this machine was first on the market, so fitting anything else is a false economy in my opinion.

With the old components removed and replacements fitted, the motor ran smoothly and fully reassembled, the machine is now ready to mix bait mixtures once again.  Lovely.

Cost of a new machine: Circa £300 and up.  Cost of repair:  £44.10 (kit plus my time).

Here’s a little video I made of the repair.

Enjoy.

I love repairing things and hate throwing things away that can be saved. There’s far too much waste in the world.  Many things that can sometimes appear unrepairable, are indeed repairable, with a little tinkering.

I want to encourage people who doubt their own ability to repair their things, to give repair a go.  Afterall, if ‘that thing’ isn’t working, grab a screwdriver, take it apart and investigate.  What have you got to lose?

I’ve been tinkering with bikes, cars, coffee machines, toys and vacuum cleaners and pretty much anything that can be dismantled since I could hold a screwdriver.  I’ve worked for BT as a senior engineer and I’ve studied design, business and electronics.

Enjoy the repair diary of a tinkerer.  I hope it gives you a nudge to repair your broken thing.
