Dyson: Please sell me the part I need

A DC32 Animal Vacuum Cleaner gets a second chance

One of these please, Dyson…

All things made, will eventually break.  Things that are made eventually wear out and either must be replaced or repaired.  However, some things wear out a little faster than others.

Planned obsolescence and manufacturing budgets mean that parts within products can wear out faster than reasonably expected and fail totally, rendering the rest of a perfectly working item, useless.

This is where us repair folk come in.  We refuse to accept this problem and work away tirelessly in sheds and lockups everywhere, working on solutions to problems such as this, keeping things going, a little longer.

A friend’s DC32 Animal cylinder vacuum cleaner’s roller beaters had stopped turning and made nothing but a horrible noise, when the cleaner was in use.  Not cool.

The roller beaters on this model are literally vacuum operated by a turbine/ fan which spins fast when air passes across it, driving the beaters by a toothed belt and gear.  There is no separate motor to drive the roller beaters, which is quite an elegant solution to a complex problem.

Fast forward to the issue and despite identifying the broken part and then contacting Dyson directly for a replacement, they would not sell what I needed, a part that would probably cost no more than £10 to supply.  Such a shame.

Copy head
FixItWorkshop, Worthing, December 2019, a copy item on eBay for under £20, screenshot 22/12/19.

The price of the (original equipment quality) complete Dyson Turbine Head, suitable for the DC32 vacuum cleaner, is £60.00 as a direct replacement from Dyson, but the part is now copied by other manufacturers.  A pattern part design is available for under £20 and if this was my machine, I’d be tempted at that price.  Pattern parts have their place, but I suspect that at this price, performance won’t be quiet as good as the original.

So, a choice:

  • Replace the part with a brand new Dyson part – too expensive
  • Replace with a non-original part, that will probably do the job – unknown outcomes, unsatisfying
  • Attempt a repair on the original part.  Of course it’s what I’m going to do!

On with the repair.  The Turbine Head is screwed together using Torx head screws and the side vents that secure the main drive unit, pop-off the main casing, with some encouragement.

A picture paints a thousand words and the above slide shows the dismantling and reassembly process for the Turbine Head.  If attempting this kind of thing yourself, remember to keep all components free of dirt and grime.

In the absence of a replacement, I attempted a repair to the existing fan and since it was made of plastic (some kind of nylon derivative I think) it was going to be difficult.  Not many glues will stick this type of plastic well, so my choice was going to be ‘make or break’, literally.  I considered an epoxy resin, but opted for Gorilla Glue, since it expands slightly in use, to all of the microscopic gaps.  I also used it to modify the fan by filling-in around the spindle to try and prevent slippage, when spinning.  When dry, I lightly sanded any high spots of glue away.

Once the whole unit was back together and reconnected to the main vacuum cleaner, the head roller beaters spun once again without a horrible noise.  Question is, how long will it run for?  If anyone thinks they can make a replacement using 3D printing, please let me know!

An orange Kenwood Chef A901! I mean, what’s not to like?

More orange please!

Why oh why oh why are more kitchen machines not orange?  I mean, just look at this beauty.  Rare-ish and as a Chef spotter, I think the only time I’ve seen another is on the kids’ TV program, Waffle the Wonder Dog on Cbeebies, here in the UK.  Do you have one in another funky colour?  If so, please send me a picture!

The Chef had actually been working for a living since it provided daily assistance in the production of artisan cheesecakes, being sold at a local market.  Recently it had decided to start a smoking habit and then go on strike leaving the owner in a bit of a muddle and customers with rumbling tummies.  That simply wouldn’t do.

Anyway, on with the repair. Opening up the casing revealed the problem straightaway.  One of the capacitors had failed and a resistor had burned out, leaving a failed circuit.

With a decent repair kit bought (from eBay), I replaced all components relating to the speed control circuit, which made the motor run again.  I also replaced all the machine’s 5 feet, since the originals had long since gone to mush, something they all do with age. Since the motor was out of the unit, I took the trouble to adjust the motor’s end float and oil the bearings, for ultra-smooth running.  Very satisfying.

With the casing all back together, I gave the machine a light T-Cut and polish to make it look as good as new and despite its 30-odd years and the odd bit of flaky paint, I think you’ll agree- it looks fab.

Sometimes, it’s not a complicated fault preventing an otherwise good machine from working.  It’s just a case of taking the plunge and getting stuck in as the owner of this vacuum cleaner had proved.

FixItWorkshop, Worthing, November ’19, Miele S5211 Vacuum Cleaner.

Sometimes the simplest things are the best.  This machine had been working well when sparks began coming from the mains plug.  The owner had reacted quickly by turning off the power and then removing the plug from the wall socket.  Good job.

The owner then bought a new plug from a local hardware shop to replace the damaged (cracked) plastic plug fitted.  She then fitted the new plug to the vacuum cleaners’ flex but nothing happened when she switched it back on.  Frustrating!  It’s reassuring to hear that folk still bother to get screwdrivers out and attempt a repair.  It makes it all worthwhile.

When I saw the vacuum cleaner and heard the back story, I immediately inspected the plug wiring and spotted that a bit of insulation was still trapped on the live connecter, preventing the electrical connection.  30 seconds with a pair of cutters and a small flat blade screw driver and the machine was working again.

Me being me, I then decided to give the Miele’s plastic casing a quick polish with T-Cut and wax, to bring it up to the correct standard.

It made me think:  How often do people change plugs these days?  Not often.  So, if you’re wondering what the correct position of the wires should be, it’s this (UK specification).

General hints

  • Make sure all screws are tight
  • Ensure the cable grip clamps the cable insulation
  • Don’t trap wires in between the casing

If in any doubt, consult a friendly shed-dweller or spanner spinner.

Genuine or pattern parts? A Dyson DC40 gets a little tune-up.

Genuine or pattern parts? What to do!?

Article 100!

It’s a dilemma sometimes.  Should you always fit genuine replacement parts or is it OK to fit quality aftermarket or pattern parts.  My answer:  It depends.

Make and model: Dyson DC40

Fault reported: Torn hose and loss of suction

Cost of replacement: About £200.00

Cost of parts: £16.53 (hose and filters)

Hours spent on repair: 1

Tools needed: Screwdrivers

Sundry items: Silicone spray, PTFE spray, rag

Repair difficulty: 2/10

Cups of tea: 2

Biscuits: 1 McVities Gold Bar

A mate of mine contacted me to ask if it was worth fixing his 6 year old Dyson DC40 and as always, I said yes it was.  A couple of days later, it was working again, like new.

FixItWorkshop, November’19, Dyson DC40.

The DC40 is still supported by Dyson and parts are readily available direct from them.  Problem is that, as my mate did, the price of some spares (although quite reasonable actually) can put some people off, which means that serviceable machinery can end up at the local dump, prematurely.  Which is a shame.

This is where pattern parts can help.  Often, aftermarket manufacturers will make spares for popular models and the advantage of these is that they are often much cheaper than the original part.  However, it’s not as simple as that.

I’ve fixed 100s if not 1000s of things and have used and continue to use a mixture of genuine original (often called OE or Original Equipment) and pattern parts for different reasons.  Assuming original equipment parts are the best, here are my thoughts, in no particular order, to help you if facing a similar dilemma.

In favour of pattern parts:

  • They can make a repair viable, financially
  • Parts can be available, long after original parts become obsolete
  • They can provide enhanced features that were not part of the original design

In favour of genuine/ original equipment parts:

  • They will fit exactly as the specification will be to the original design
  • They maintain manufacturers warranties, where applicable
  • They normally last well and perform as expected

As a further example, I will only fit genuine water pumps (on car engines) but will fit pattern air filters.  Water pumps must work within very exact performance tolerances whereas air filters, although important, don’t so much.  It’s a personal thing at the end of the day.

Back to the repair.  This Dyson wasn’t picking up dirt and the extension hose was torn, so a new hose was ordered from a supplier on eBay for under £10, a genuine part was over £25.  The hose just clicks out and in, so all that was required was a small flat bladed screwdriver to remove and refit the hose.  Nice and easy.

The next job was to sort out the lack of suction.  As with all Dysons with a problem like this, I always check filters.  As suspected, both filters were expired and needed to be replaced as they were too far gone to be washed.  Again, pattern part filters were available on eBay for under £7, genuine ones were much dearer.  All new parts fitted well and soon the vacuum cleaner was breathing easily again.

Another issue with the DC40 is the switch lever which diverts suction from the beater head to the hose, which was sticking on this machine.  A quick clean up and a small spray of silicone spray on all the moving parts had it all working again.

I always clean-up the beaters on any vacuum cleaner in for a service and this one seemed to have half a head of hair stuck in it, which would have impeded performance.  The hair was so bad, I had to remove the beaters (just one screw) and cut off the hair with a knife.

With all the remedial work completed, the Dyson ran well proving once again that it’s usually worth repairing, rather than replacing.

 

Dyson DC25 with various problems

Another Dyson dodges the dump

An email dropped into my inbox about a poorly Dyson DC25, that needed a bit of a clean up.  I said no problem, I’ll take a look.  What turned up was a vacuum cleaner that needed a bit more than a quick clean up with a J-Cloth.

Make and model:  Dyson DC25 (blue/ grey)

Cost of replacement:  £N/A, price when new £300

Cost of parts:  £6.89 (plus my time)

Hours spent on repair:  2.5 (plus testing)

Repair difficulty:  5/10

It soon became apparent, that the Dyson was quite ill.

Here’s a summary of the problems:

  1. The mains cable flex was split, exposing the internal cables risking electric shock
  2. The roller beaters would not spin
  3. Suction was limited

None of these features were useful in vacuum cleaner, so out came the screw drivers.

The mains flex damage was about 90 cms from the handle end, so rather than replacing the whole cable at about £30, I decided to shorten the one already fitted on the Dyson.  This involved removing three screws on the reverse of the handle to expose the wiring.  From there, the broken flex could be cut-out and the sound part of the flex, reattached to the Dyson’s wiring.  See below.

The DC25 features a roller-ball, enabling the beater head to twist and turn in to tight spots on the floor.  This means that mains power must navigate the various joints and hinges on the way from the main body to the roller beaters.  A quick test revealed that the power was not getting through.  After removing one of the side covers, there was evidence of a previous repair.  One of the mains cables had broken and had then been twisted back together.  Clearly, an improvement was needed.  Using a section of repair cable, a small joint was soldered back in to place with some mains-rated heat shrink around the connection for insulation and reinforcement.  See below.

The beater head also needed a good clean, which meant a strip-down and re-build.  All parts were cleaned, inspected and reassembled.  During that process, a small break in the beater head wiring was found, repaired and put back together.  See below.

Finally, the machine needed a good clean up.  The main cylinder was washed, the filters washed (although I later decided to replace these) and the main seals on the vacuum system, cleaned and silicone sealed.  See below.

During clean up, the spigot-yoke that holds the roller ball in place on one side was found to be missing.  Luckily the owner had kept this and dropped it back to me to re-fit.

This Dyson was on the brink, but with a little bit of spanner-time, it’s now ready to serve many more years.

 

 

 

 

Gaggia Espresso Machine with a nasty blockage

A Gaggia Espresso machine gets a rebuild.

Home coffee machines are very cool.  Home espresso machines are even better as they’re the closest you can get to a coffee shop brew, in my opinion.  Due to heat, water and coffee mixing up on a regular basis, they need ownership with care for long life.

IMG_9039
FixItWorkshop, Worthing, May’19, Gaggia Espresso Machine.

Top tips for longer coffee machine life:

  • Use filtered water, especially if you live in a hard water area
  • Clean the tank regularly
  • Keep all rubber seals, especially those around the main coffee making area, clean with a damp cloth

Someone got in touch with a machine that was a few years old, but had once made a lovely cup of coffee.  The owner had used it daily but recently it had begun to leak and not perform at its best.  The machine had also been to a UK repair specialist, but sadly, they couldn’t solve the problems.  I always test appliances when they arrive to confirm the fault and as expected, water came out of places it wasn’t supposed to.

I’ve worked on a few of these machines, so I know the drill.  Remove the lid, make a note of the wiring connectors, the pipes and remove the bolts holding the main boiler in place.  I also ordered a service kit (new seals) for a reasonable £7.99.

The main boiler separates into two halves which reveals the main boiler chamber and exit for hot water.

This boiler was in poor condition and years of corrosion and scale had built up and was probably blocking the main group head, the bit where you attach the group handle/ filter bit to make coffee.

Time for more dismantling.  The group head is held in position with a couple of screws, but years of corrosion had taken their toll and this head was going nowhere.  Great care was needed as the soft metal is easily damaged.

Thinking about this a bit more, I decided to cut a screw thread into one of the water holes in the head and use a bolt to lever the group head apart.  It worked.  Once off the head revealed loads of debris and scale.

The next job was to give all parts a thorough clean, re-faced with wet and dry paper as needed and use new seals as part of the reassembly.

Once back together, the boiler was reinstalled and reconnected.  After a few blasts of fresh water through the machine, it was ready to make its first proper brew.

Cost of replacement:  £100-300.  Cost of repair:  £7.99, my time, one tin of elbow grease, one cup of coffee and a ginger nut.

 

 

Leave the light on…

A Philips outdoor wall lamp with a major case of built-in obsolescence, gets a cheap fix.

A mate of mine mentioned that his outdoor wall light had given-up-the-ghost, despite not being more than three years old.  He’d put them up around his house as part of an extension and exterior restoration project.  The trouble was that despite only being a few years old, the product now seemed to be discontinued.  This meant that, should the lamp need to be replaced, he would need to replace all of them (three in this case) to keep them matching.  Annoying quite frankly.

IMG_20181112_194358.jpg
FixItWorkshop, March’19, Philips outdoor wall light, working.

He’d read that the bulb within the Philips lamp was not replaceable, in which case a faulty lamp would render the whole thing broken, which seemed very daft to me.  Items made in such a way that prevents even the most basic of repair get me very annoyed.  Sometimes an item is developed in such a way for safety reasons but I suspect that most of the time, the motive is just pure greed.  It’s such a shame.

At my mate’s house, over a cup of tea, I removed the lamp from the wall to take back to the workshop, to see what Philips had been getting up to.

Opening up the casing was straightforward, just a few simple screws and retaining nuts holding the casing together, before finally revealing the bulb itself, under a lamp diffuser.

IMG_7609
FixItWorkshop, March’19, Philips outdoor wall light, lamp unit.

The bulb/ lamp unit itself appeared to be a custom/ bespoke disc light, that wasn’t user serviceable.  It had blown and there was evidence of scorching on a few of the LEDs, linked in series, indicating the failure of the entire circuit.

I couldn’t find any replacement disc LEDs suitable for the lamp from any of the usual sources, which I expected.  It could be that Philips can supply a replacement disc, but this was not evident on their website.

Not wanting to be beaten by a bespoke part, I thought about what else might work, within the lamp’s enclosure, to have the same effect.  I had a spare GU9 LED bulb, about the same brightness, sitting on the shelf, left over from another project which was going spare, so I set about fitting it in the space.

The generic GU9 bulb, available from most hardware shops, fitted in the existing disc mounting bracket, with a small modification and once connected to the lamp’s circuitry, worked well, albeit with a slightly warmer glow.

In case anyone else has the same problem, I made a little video of the repair.  I hope it gives others inspiration if faced with a similar problem.

Cost of replacement (with something similar): £50.00.  Cost of repair:  £1.50 for the bulb and a couple of Belgian beers for my time.
