I love a good radio. I used to collect them as a kid, working or not, do them up, get them working and I eventually ended up with, er… lots. I’ve since scaled my collection back a bit these days to around 10 or so, quite frankly more than is healthy really.
So when someone got in touch recently with a broken DAB radio to fix, I got quite excited.
These Bauhn DAB radios (available from Aldi or Lidl in the UK, I think) were on the market for about £10 and at that price they represent great value when compared to more expensive devices.
However, the one in the workshop appeared to have a problem power connector, which when wobbled, made the radio work intermittently. Suspicious.
Having already repaired a similar radio with a similar fault before, I decided to video the repair to encourage others to check theirs, if something similar happens. I hope you find it useful.
Cost of a new radio: £10. Cost of repair: One cuppa and a bit of tinker time.
Another Kenwood Chef A901 gets the Workshop treatment…
There’s been a steady flow of poorly Kenwood Chefs through the workshop of late and the new year started off with yet another. A customer got in touch with reports of smoke coming from her Chef A901, a machine which had given years of faithful service to her family. As a result, she was very keen to see what could be done.
As usual with Chefs of this age, the 5 machine feet had deteriorated and now resembled squashed dry Blu-Tac, so had to be replaced. I replace the feet to most Chefs that come in. Not only do the feet prevent the machine from moving all over the place when in use, they provide a gap for air to be drawn in to the motor for cooling, so it’s essential the feet are in good condition.
The feet are inexpensive and are easy to fit. If you decide to replace yours, consider coating the existing ones with something like WD-40, a few days before you try to extract the centre pin or you risk snapping it off in the machine base, as it will likely be ceased.
On with the repair. The speed control circuitry had failed, specifically a capacitor and resistor, a common problem on older machines, had gone pop. As usual, the correct repair kit was bought and fitted. With careful soldering and a dab of heat transfer gel on the new triac and the job was complete. Nice.
With any Kenwood Chef, I always check the motor end-float, the allowable spindle movement north and south. The end float in this case was a little lose and required adjustment. A small grub screw with Allen key head allows this adjustment and with a bit of trial and error, the end float was now spot-on. Poor end float on these machines usually makes the speed control ‘wobbly’, especially at lower speeds. With this one adjusted correctly, the motor now ran smoothly through all speeds.
Job done. The owner of the machine was so pleased with my work, she even bought me a new packet of Custard Creams. Fab.
Cost of replacement: £400 and up. Cost of repair: £11.24, plus my time and Custard Creams!
Christmas wouldn’t be complete without having to fix last years’ tree lights and this year was no exception. It’s a tradition I look forward to and savour.
Gone are the days spending hours trying to find a faulty bulb, now due to the wide availability of cheap LED products, the thing that’s often likely to fail is the wiring, something which was much more unusual, a few years ago. Manufacturers must make savings somewhere and I often wonder how retailers can offer new decorative lights, so cheap. Compromises must be made somewhere I guess.
Being cheap, like a lot of things, makes them more disposable, which is a shame when things fail, often for trivial reasons. This year’s blackout was caused by a couple of broken wires on the control box, which didn’t appear to have any obvious way to get inside.
We don’t like to be beaten in the workshop and sealed units and tamper-proof items are just seen as a challenge, rather than a deterrent.
Like many multi-function sets, the lights are operated via a control box with a switch, mounted in a plastic enclosure which appears sealed. The fault was obvious here, just the main wire from the transformer had broken ‘flush’ with the control box, meaning that there was not enough wire either side of the break to re-join it.
The control box has no screws nor visible clips, holding it together, so it was time to break it open, using a small flat-bladed screwdriver. The small section covering the wires snapped off cleanly, revealing several terminals covered in hot melt glue, annoyingly. This meant that before any repair, the glue must be removed. Several minutes picking this off with the screwdriver, revealed some conventional post terminals. The fix was easy from there, just cut down the wire to make a new connection, remembering which way round they went, clean up the terminals and solder back together. A little bit of fresh hot-melt glue to seal the connection and a bit more on the surface to be stuck together, and the cover was refitted. I also fitted a little heat shrink to repair to reduce the chance of the cable from breaking again.
As I had the soldering iron out, I also did a small repair to the control box wire to transformer plug, which had also broken. It was a case of cutting back two sides of the break, soldering, isolating with a small amount of electrical tape and sealing with heat shrink.
Now that’s all done, Christmas can now officially start.
Cost of replacement: £ 5.00 up. Cost of repair: 1 cup of tea, heat shrink, tape and solder.
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.
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.
My mum’s got an old electric Singer sewing machine which is about 40 odd years old. Singer sewing machines are well supported generally and parts are readily available, but I find it’s sometimes fun to try and find the cheapest way to fix something myself.
The foot pedal on this machine went pop and smelled horrible after. The machine then stopped working, oh dear.
The pedal is of high quality construction and easily better than any generic replacement on the market, so it was definately worth saving.
Opening up the pedal was just a few screws, which then exposed the whole mechanism. The mains resistor was in tact and seemed to test with resistance. A good start. The contacts were in good condition as was the rest of all the components, except for the mains input capacitor, which has spectactularly failed and split open, a common problem on older mains capacitors.
Repair kits are readily available for about £5, but that seemed expensive to me! Using the existing capacitor as a guide, I found a suitable component on eBay for £2.09 delivered. That’s more like it.
The capacitor I used was: Film Capacitor, 0.1 µF, 250 V, PET (Polyester), ± 5%, R60 Series (from eBay).
Here’s a little slide show that I hope will help others fix their pedal, should it fail.
With the old capacitor cut out and the new one soldered in, the pedal was ready to run again. Sorted.
Cost of a replacement: £15-30 for a generic part. Cost of repair, £2.09, 1 cup of tea.
I really had no idea that Micro Scooters have been a ‘thing’ for the last few years and as a result, there are lots to choose from on the second-hand market. We picked up a ‘bargain’ for our oldest daughter for a princely sum of £5.00 via a local Facebook For Sale page. With hindsight, it was overpriced.
Just about every part of the scooter was either nasty or plain broken. The handle bar grips were missing, the wheel bearings were all shot to pieces, the steering mechanism seized and the rear brake was missing. The back brake on this scooter type, I’ve since found out, have a habit of snapping off with hard use, so that should have been the clue to the low, low price. But if you read these pages, you know me, I like a challenge.
First step was to address the static wheels. An Allen key holds the wheels on to the stub-axels at the front of the scooter and there’s something similar on the trailing wheel. The bearings on our wheels were beyond a re-grease as they’d appeared to have spent their entire life at the bottom of The Channel.
Luckily, the bearings are easy to replace and good-quality generic items are available on eBay for under £5.00 for a whole set (6 bearings, 2 per wheel).
Next came the handlebar grips. Ours were missing and again, generic ‘copy’ grips are available on eBay which are perfect for the job and are half the price of the original equipment. While I was shopping on eBay, I also found an original Micro Scooter bell. Just the job.
The steering mechanism was next and all it needed was a good clean up and light lubrication with some plastic-friendly white PTFE grease, readily available from Toolstation.
The shabby foot plate area was once baby-blue but had since faded and had evidence of scrapes. It looked a bit sorry for itself. I decided to address this by giving surfaces a good clean up and then key with wire wool. A couple of coats of good quality plastic primer and then a couple of coats of vinyl black paint, which now gave the scooter quite a ‘presence’. I then decided to improve the foot plate ‘grippy-ness’ by applying a custom grip tape design.
Before re-attaching the foot plate back to the chassis, the brake needed to be replaced. As with some of the other fixings on the scooter, the brake’s fixings were so rusty, they needed to be drilled out and replaced. Luckily the new original equipment brake came with new improved fixings which fitted perfectly.
I know what you’re thinking… for £40 more, I could have bought a brand-new scooter and saved myself the bother. At times, I did question my own sanity. But what we now have is a perfectly serviceable, one-off that no one else will have. Can you put a price on that?!
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.
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!
