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.

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.

Dyson DC40 missing a beat

A small repair on a Dyson DC40 leads to a big improvement.

A powerful, easy to manoeuvre vacuum cleaner, that gets into every nook and cranny.  But not this one.

FixItWorkshop, Worthing, May’19, Dyson DC40.

Three top tips for keeping your Dyson DC40 in rude health:

  • Keep all filters clean (wash or replace frequently)
  • Clean all rubber seals with a damp cloth to remove dust build-up
  • Occasionally lubricate moving parts of jockey wheel mechanism (springs and lever) with silicone spray

Do these things and your Dyson will love you forever.

I’m a bit of a sucker for Dyson products.  They are well engineered products from the school of function over form and in my opinion, objects of art.

This Dyson wasn’t very well when it was admitted to the workshop.  The owner had complained that the vacuum cleaner wasn’t picking up dirt and dust properly.  The beaters were not spinning either.

IMG_8890
FixItWorkshop, Worthing, May’19, Dyson DC40 beater head.

The beater ‘head’ is attached to the main body of the vacuum cleaner and is held in place with a sliding clip.  The head can rotate and move to allow maximum control.  The beater roller is driven not via a belt from the main motor, but from its own smaller motor in the head unit.  So, there is an electrical connector between the main body and head unit.  As the beaters were not spinning, it seemed sensible to test the electrical connection.  Upon testing, it was not working.

The mechanism on this vacuum cleaner is quite complicated and relies on levers and joints working in harmony.  Dismantling the wheels, filters, brackets and covers around the motor revealed the problem.  The supply that feeds power to the beater head is routed around the motor and sliding lever mechanism and a broken cable was to blame for the beaters not spinning.

Access was difficult due to the design so rather than completely tearing down the body to replace the supply loom, I reattached the broken wire with some soldering and heat shrink to make a robust repair.

After carefully rerouting the cables and reassembling the body, wheels and beater head, the beaters spun once more.  Result.

After a new set of filters were fitted and a light service, the machine was as good as new.

Cost of replacement machine:  £000’s.  Cost of repair parts: £11.69 plus my time and two teas.

A Dyson DC34 Animal dodges the bin

A repair and top tips for keeping your Dyson DC34 running for longer.

Every home should have one of these hand held dust busters.  Simple as that.

FixItWorkshop, Worthing, May’19, Dyson DC34 Animal.

Why?  Because they are easy to use, easy to clean and last ages on a charge.

Top tips for keeping your Dyson DC34 running for longer

  • Keep the filter cleaned (wash regularly)
  • Remove any build-up of hair from the roller beaters
  • Keep all electrical connections clean (use WD40 or similar)

This one was admitted to the workshop with one fault, but the diagnosis revealed two problems.

When in use, the roller beaters would stop frequently and not restart.  The cure for this problem was to remove all the hair from the roller spindles and the internal motor belt drive, which was held together with a couple of screws.  Once all the hair was removed, the rollers worked much better, but not perfect.  A quick blast of air and a quick spray with contact cleaner into the motor and the rollers were once again, working as they should.

On a full charge, one of these Dysons should run for about 20 minutes, but this one didn’t.  The battery wasn’t holding the charge, so after a quick look online, a new one was purchased for just under £20.  Great value.

It felt really good to save another product on its way to the bin.

Cost of replacement:  £200.  Cost of repair:  £20, plus one cuppa, ginger cake and ice cream.

Dyson DC14 with no vacuum

Another Dyson repair…

As covered a few times on my blog already, I do like Dyson products.  They’re engineer and tinker-friendly.

IMG_8360
Fixitworkshop, March’19, Dyson DC14 (PS, I did clean the old paint off later).

A colleague got in touch with a poorly DC14 which had worked well.  She’d kept the filters clean and generally looked after the appliance with care, which makes a nice change. However, despite all this, nothing was being collected with the floor beaters.  The hose worked OK, but that was it.

Time to do some screwdriver wealding.  Despite the filters being in good condition, I washed and dried them anyway, just in case.

Up ending the vacuum cleaner revealed the problem straight away.  The bottom foot hose had become disconnected from the interference fit compression joint and was flapping in the breeze.  Usually when this happens, it’s because the hose has split, but this one was in good condition.  What seemed to have happened was that the hose had become untwisted from the joint, so all that was required was careful reassembly.

While the cleaner was in pieces, I gave it a thorough service, paying attention to all of the machine’s seals and moving parts, especially where the cylinder joins the vacuum pipes from the motor as these can leak with age.

Once spruced-up, the cleaner was back to full health once again.  Another Dyson saved from the tip.

Cost of replacement:  £150 and up.  Cost of repair: Time, tea and biscuits and silicone spray, a bit of washing-up liquid.

Classic (asthmatic) Dyson DC01

A tired DC01 gets some TLC

Starting a new job is always fun and when a new colleague of mine mentioned that the office vacuum cleaner had packed up, I rose to the challenge.

I’m quite fond of Dyson products as some of you know, mainly because:

  • They’re well-engineered, by engineers
  • They’re designed to be repaired easily with simple tools, which is better for everyone
  • Parts are readily available at reasonable prices

The DC01 was launched in the early 90’s and was Dyson’s first market clean-up, competing with the established market leaders.  Although this machine is over 20 years old and Dyson no longer supports it directly, reasonable quality pattern parts are available on eBay.  If you have one, love it and keep it going.

FixItWorkshop, Worthing, November’18, Dyson DC01

This one is actually an ‘Antarctica Solo’ model (grey and light blue instead of yellow), which commemorated Sir Ranulph Fiennes’ solo trek across Antarctica and raised money for Breakthrough Cancer.  It had been abandoned and was moments away from the skip.  I felt quite sorry for it.

Faults reported included; no suction, excess noise and smell!

The first thing to check on the DC01 is the filters, as like many other Dyson products, people forget to clean or change the filters.  Both filters were totally choked and full of all sorts of detritus.  A quick shake out and wash with warm soapy water and they were as good as new.  Following that, I inspected the seals around the join between the cylinder and the main body.  All the seals were dirty, so a clean up and quick spray with silicone spray and they were as good as new.  Great.

The noise seemed to be coming from the front beater/ rollers which usually means, noise bearings.  The beater on this model uses a two bearing set up.  One was fine, but the other was seized.  As I didn’t want to spend any more than I needed, I cleaned the bearing, after removing it and the dust cover, re-greased it with LM High-Melt Point grease (general automotive stuff) and it was ready to roll and beat again.

Once the filters were dry and re-installed, the Dyson ran like new again.  Very satisfying.

Cost of replacement:  £15 second hand, £100’s for an equivalent-ish new model.

Cost of repair:  Patience, washing up liquid, two cups of tea.

Unsteady Dyson DC24 Roller Ball

A neglected DC24 gets some badly needed maintenance…

I really enjoy working on Dyson products as they’re so well thought out.  The designers seem to take great care factoring-in easy maintenance for longevity.  There’s also a great sense of theatre when using Dyson products.  Take the roller ball on this design for example, a throwback to the earlier Dyson Ball Barrow which allows better manoeuvrability when combined with an upright vacuum cleaner.  There’s also the exposed mechanism which automatically switches suction between the roller pick-up and hose when using the foot pedal to select the desired mode.  Genius.  All of these design touches encourage the user to care for and enjoy using the product.

IMG_5640
FixItWorkshop, April’18, Dyson DC24 (DC04 just in view too- how things have changed).

Sadly though, sometimes these touches are a bit lost on people and the design flares that appeal to some become misunderstood and neglected to others.

This DC24 had two problems.  It didn’t stand up properly when left and it didn’t really pick anything up that well either, failing as a vacuum cleaner on two fundamental points.

The first job was to find out why the DC24 was a little unsteady.  It seemed that all of the mechanism was intact and that nothing had snapped off.  Strange.  The red foot pedal operated lever that releases the latching system to move the main body from its locked position was stuck.  It seemed to be linked to a lever which operates the diverter valve, which switches suction from the roller beater foot to the flexible hose.  On closer inspection the lever on the diverter valve had come off its pin, probably by force.  The mechanism itself was also dirty which made operation rough.  The red lever is spring loaded with guides and pins which were also dirty and a little rusty.  I suspect this vacuum cleaner had been left somewhere damp.

After re-attaching the diverter valve leaver back on and giving all mechanisms a good clean-up with a light coating of silicone spray, it was as good as new again.

Once the mechanism was working, it was time to assess the vacuum’s performance.  It wasn’t that good.  As with most Dyson vacuum products, there are two filters.  One processes blow-by air from the motor and the other controls dust particles from the cylinder.  These filters can usually be cleaned with mild soap and water, but this set was well past it, requiring replacement and for under a tenner, it’s rude not to.  Dyson have made filter replacement very easy on the DC24 with good access to the motor filter via a small door on the roller ball itself and the lid on top of the cylinder.  I think there should be a massive sticker on these vacuum cleaners that says ‘don’t forget to clean the filters’ as I suspect that many of these products are chucked away by owners who forget to do the necessary.  Bag-less cleaner doesn’t mean maintenance-free!

With a couple of new filters, a clean-up of all of the rubber seals with silicone cleaner and this DC24 was fighting fit, ready to clean another carpet.

Cost of a replacement Dyson product:  £000’s.    Cost of new parts:  Under £10 plus my time.

 

Hybrid Hoover-VAX vacuum cleaner combination experiment…

Recycling vacuum cleaner parts.

A slightly unusual workshop repair this time.

My brother-in-law popped in to see us for a cuppa recently and mentioned he was off to the tip with an old VAX cylinder style bag-less vacuum cleaner, in pieces, not the carpet washer type.  It was on its way to the great scrap yard in the sky.  Luckily, I was on hand to divert the sick VAX via the workshop.

It was being disposed of due to the flex having gone faulty together with the opinion that it wasn’t working that well before the mains cable failed.  Well, I hate to see good machinery go to waste.

On this VAX, the mains flex is stored within the vacuum cleaner housing and is wound up on a spring-loaded coil during storage.  When in use, the user can pull the mains plug until the desired cable flex length is reached.  When the user is finished cleaning their carpet, a foot operated button causes the flex to speedily disappear back in to the vacuum cleaner.  My brother-in-law had already looked at the spring-loaded mains flex winding mechanism, which had resulted in the bi-metallic coil spring escaping from the enclosure, freeing itself in to an orbit.  It’s quite a shock and sometimes dangerous when this happens!

What to do.  I was very nearly tempted to dump this vacuum cleaner too as the build quality of the whole thing reminded me of the plastic toys one gets in Christmas crackers, but that’s not really in the spirit of The Workshop.

Then I remembered I had a defunct Hoover Telios that was minus a motor, perhaps this would be a suitable parts donor?  I liked the idea of making one working vacuum cleaner from two unhappy ones.

The Telios had a working mains lead flex, but the automatic spring loaded mechanism on that was past its best, so I decided to use the working lead on the VAX.  The VAX would be without its flex winding mechanism, but at least it would work.  I adapted a cable tie to make a cable grip, to prevent a user from pulling the cable from the VAX, when in use.  The cable would have to be stored, wrapped around the vacuum cleaner, after use, a small price for working machine.

FixItWorkshop, Feb’18, VAX cylinder vacuum cleaner.

The other job was to address the poor performance.

This product is clearly an inferior Dyson rip-off and therefore has a couple of filters; one for the intake and one for the exhaust, like a Dyson.  As suspected, both of these were virtually blocked!  The filters on this model were not as easy to get at nor as easy to clean.  I’m not sure whether these filters are meant to be washed, but wash them I did and after 24 hours of drying on the radiator, they were as good as new.  Once refitted, full performance was restored, for the price of a bowl of warm water and Fairy liquid.

Finally, the VAX was missing its cleaning head for the hose, so I decided to use the Hoover one (which was quite a nice design) with the VAX’s hose.  After some jiggery pokery and some electrical tape, it fitted.

What we’ve now ended up with is a working VAX vacuum cleaner, using some parts from a beyond economical to repair Hoover.  Whilst it’s not the most elegant repair I’ve ever completed, I now have  something working from two nearly condemned items and surely, that’s good thing?
