Fetch me a coffee Parker… Yes Milady!

A Gaggia Milady gets unblocked

Despite various warning labels and advice from manufacturers, sometimes it’s better to ignore official advice and just dive in, especially if something has stopped working altogether.  Gaggia coffee machines of this vintage are well supported by various online parts suppliers, so when your machine stops making the perfect brew, the chances are that it can be sorted out with a little know-how…

Someone got in touch to see if I could repair their much loved Gaggia Milady, after receiving some unhelpful advice from the UK distributor.  A new Gaggia had already been purchased, but the owner was missing the ‘solidness’ of his original machine and wanted it back working again.

Fault reported:  Heater working, pump running, no water at all at the group head, therefore no coffee.

Opening the machine’s lid reveals lots of cables and pipes, so if you’re attempting this repair yourself, I recommend making notes and taking photos, carefully marking the location of all the positions.

I suspected a blockage from the boiler to the group head, as sometimes happens with older machines, as scale builds up on the inside.  In cases like this, de-scaler is usually no good and more drastic action is required.

Removing the boiler on this model is similar to many other Gaggia machines, the only variant differences usually being cosmetic.  Just four screws usually hold the boiler to the cabinet.  I suspected that there was a blockage between the boiler area and valve to group head ‘jet’ and in order to access it, a few layers of metal work needed to be removed.

Just one screw holds the strainer, but removing the head involves removing two bolts, which secure two halves of the group head.  The trouble is that over the years, corrosion makes the two halves ‘weld’ together and the only way to split them is to use a little ingenuity.  Fortunately, there are four water holes in the head which make ideal leverage points and with a small M5 tap, those holes become anchor points for the two bolts holding the head together.  Winding those bolts into the new threaded holes forces the two halves apart…

…Revealing the brass valve base.  Using a 10mm spanner releases the valve’s spring and valve rubber.  In this case, it was full of scale and debris.  A thorough clean using WD40, wire brushes and wire wool and the group head was ready for reassembly.

All surfaces scrubbed, all rubber seals cleaned and treated to some water-safe lubricant, the group head back together, the boiler was ready to be re-installed into the machine.  After some careful re-plumbing and re-connecting, the machine was ready for testing.

Just one more job.  Make the coffee for Milady!

Another machine dodges the tip with only a small tin of elbow grease used. F.A.B!

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.

 

 

Blocked Hoover Steam Cleaner

Hoover Steam Cleaner Repaired!

I’ll put money on the fact that many steam cleaners like this one are thrown away needlessly due to blockages which could be easily cleared using everyday items.

This Hoover S2IN1300C hand held steam cleaner appeared to switch on OK (LED lamp on), the pump ran OK, but even with a full tank of water, no steam came out of the steam nozzle.

Off with the cover and after checking the pipes for leaks and pinches, it appeared that all was well.  The pump did indeed run and the boiler appeared to get very hot.

After a fair bit of dismantling, it appeared that the nozzle was blocked by a build-up of chalk.
