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.

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.

 

 

Very leaky Renault Clio

A Clio gets it’s drains cleared

I’ve owned my fair share of banger material motors, but I’ve never known one as rain intolerant as my latest car.  I bought a ‘one owner’ Clio for not a lot of money, as a hack to get to work.  The car was very honest.  It honestly told me that not much in the way of maintenance had been done- in recent times.

Anyway, £60 or so on service and maintenance parts later and the 120K mile machine responded well, trouble was, that I needed a brolley and wellington boots to drive it, it leaked so much.  My 1983 Austin Mini was more water resistant, it was that bad.

After doing a bit of Googling, I found that the classic Renault fault with the sunroof seals had plagued my car, but that wasn’t the end of my problems.  Both door card gasket (the gasket between the door card and metal) had failed.  A reel of £6.99 mastic tape fixed both sunroof and door card leaks, happy days.

However, when it rained hard, I still needed wellies to drive.  This leak was eventually traced to a hidden drain hole, buried deep within the bulkhead/ scuttle area.  A few videos on YouTube mention this, but I thought it was still video worthy to cover again with the wiper mechanism and heater blower removed to see the drain more clearly, in the hope it might help fellow Clio Mk2 owners with perpetual Athletes foot.

Enjoy!

G.E.T. Dehumidifier with damp issues…

GET dehumidifier with damp issues…

Over a cuppa, my mother in law mentioned that she was chucking out a dehumidifer this weekend and had already replaced it.  This was a shock to me since it hadn’t started it’s journey to Worthing tip via my shed yet.  Time to intervene.

FixItWorkshop, Jan’18, GET Dehumidifier repair.

Aparently it had overflowed water all over the floor and had cut out and not restarted.  It had probably been left to its own devices in their cellar, totally neglected in the run up to its demise.

Before worrying my toolbox, I usually plug things in and press buttons to see what happens.  When connecting this dehumidifier to the mains, it fired-up and seemed to run perfectly.  Strange.

Looking at the device in more detail revealed three tell-tale LED lights (cooling, empty the tank and running).  The tank was removable from the front and featured a small float operated level which married up to a small microswitch.  The idea being that when the water rose to the top, the switch would be activated by the float and the machine would cut out safely, all being well.

The lever mechanism on the float seemed to be stiff and all that was required to restore service was a good clean with a brush and Fairy liquid and some silicone spray, once dried.

While giving the unit a general inspection, I noticed dirt in the units’ grille.  Fortunately, the grille had a removable filter which had clearly never been cleaned, so in effect had been chocking the dehumidifer in normal operation.  Bad news.

Piecing the evidence together in my mind surrounding the causes of failure, I came up with the following theory.  The float had failed, causing the unit to leak.  The unit had then run hot, probably for a while and had probably tripped a thermal protection fuse.  I have no evidence for the latter idea as I never opened up the unit fully, but the theory fits the sequence of events.

In any case, the dehimidifier now switches on and switches off when full and doesn’t seem to run hot.  I was pleased with that.  I wasn’t so pleased that my in-laws wanted the unit back.

Cost of replacement: Circa £100.  Cost of repair; cleaning stuff.

 

Gaggia Classic machine wakes up to smell the coffee.

A Gaggia Classic Coffee Machine repair…

A simple repair…. That’s what I thought when a friend asked if I could look at his Gaggia Classic Coffee Machine, which had developed a nasty little leak when in use.  The coffee wasn’t all that good either, due to the lack of pressure available, caused by the leak.  In short, it needed attention.

FixItWorkshop, Oct’17, Gaggia Classic Coffee Machine, with a leak.

The owner had already bought a repair kit consisting of the main seals/ gaskets that commonly fail, so I thought no problem, take to pieces, replace seals, happy days.  Er, not quite.

Once I’d stripped the machine down, pretty straightforward on these machines, the bare parts were exposed, which revealed the problem.  After being fired up briefly, not to make coffee I’d like to point out, water could be seen escaping from the boiler unit, a alloy bodied lump of metal, split in two halves, held together by 4 screws.  The boiler, as the name suggests, heats the water up with one heating element  and creates steam for the steam wand, with another element, all part of the same module.

After separating the boiler halves, I traced the leak to a faulty gasket, but crucially, one side of the mating faces was heavily corroded and unlikely to re-seal with a new part fitted on its own.  Remedial action was required.

This model is a few years old and a replacement boiler is still available on a few websites and prices vary from £40 to £60 at the time of writing, so at that price, starts to make the cost of repair unviable.

I decided that the face with the corrosion had enough material to withstand loosing some, so went about sanding the worst of the corrosion away before gradually moving on to  smoother and smoother sandpaper.

Because Gaggia Classics are fairly common, I decided to video this repair process as I suspect the corrosion affects many machines with age and just fitting a repair kit won’t cure the problem on its own.  See below.  I hope it helps anyone else with the same machine facing the same problem.

 

Once I was happy with the new finish, I fitted a new gasket and reassembled the boiler.  After putting it all back together, I purged several tanks of water through the system to remove debris, before attempting a cup of coffee.  Once filled up with my favourite Lidl coffee, the machine performed well once again with no leaks and the end product tasted great.

Cost of a new machine:  £249.00.  Cost of repair:  £4.50, plus time.

 

 

Porsche Boxster leaky window seal

A little water leak repair on a Boxster.

Not strictly a FixItWorkshop blog article really, but hey!  It’s a cheap fix.

My beloved 2003 Boxster developed puddles in the umbrella holder on the passenger side (RHD car) when it rained hard.

The window was adjusted correctly and the door aligned properly, but when it rained, water ran down near the door mirror, under the seal, down the door card and in to the umbrella holder area.  Water leaks like this, especially on the passenger side (RHD car) are a real problem on the Boxster, since the cars’ ECU is mounted on the floor on that side and is big £££ to replace/ repair if it fails.

Seemingly, the door seal rubber on the car adjacent to the door mirror area had worn and become slightly porous and was allowing water to get in between the glass and seal.

New door seals are very expensive and to prove the issue, I applied a small trace of tap (faucet) silicone grease to the area to restore the wax-like finish, the seal should have to seal properly.

This has fixed the problem for now.  The door seal is worn and will need replacing in the long-term, but for now, this is a very cheap fix.

 

Leaking Reginox Miami Tap

Reginox tap gets a new mechanism.

A friend of mine had long been complaining about a leaking tap in his kitchen for some time, so it was a long overdue job for me to tackle.

A quick look online revealed lots of videos and help, but nothing covering the actual problem in this instance.

The tap spout was leaking from the swivel joint where the spout body is allowed to move approximately 180 degrees to move from sink to sink, in this case.  This is a fairly common problem for taps (faucet if you’re in America) of this design and sooner or later they all seem to suffer.

I was interested to know if the parts were available, but Internet searches revealed nothing.  An email to Reginox UK was answered very quickly and I was referred to Mayfair Brassware Ltd, the manufacturers of the tap in this instance.  The parts were quickly identified and delivered next day. Both companies were very helpful and efficient, useful for a non-plumber, like myself.

The cost of replacing the tap was about £50, so the £5 spent on replacement seals was well worth it.  The whole job was done in 10 minutes using basic tools.

 

Incontinent Porsche Boxster (986)

An annoying leak, sorted.

A slight departure from my usual ramblings about white goods and other domestic appliances in this entry.  Outside of The Workshop, I’m a keen petrol head who loves to tinker with cars and motorbikes and my own car was suffering from a recent bout of coolant incontinence.

Like me, most owners of these cars dread anything like this happening as it usually means big money.

The leak only happened when the car cooled after it was was run up to temperature and was evident in the area under the oil filter housing.  Luckily, the leak wasn’t serious and was repairable with a 10mm spanner, washing-up bowl and 4000 grit sandpaper.

Here’s a little video which I hope will help other Boxtser owners.
