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.

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.

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.
