Genuine or pattern parts? A Dyson DC40 gets a little tune-up.

Genuine or pattern parts? What to do!?

Article 100!

It’s a dilemma sometimes.  Should you always fit genuine replacement parts or is it OK to fit quality aftermarket or pattern parts.  My answer:  It depends.

Make and model: Dyson DC40

Fault reported: Torn hose and loss of suction

Cost of replacement: About £200.00

Cost of parts: £16.53 (hose and filters)

Hours spent on repair: 1

Tools needed: Screwdrivers

Sundry items: Silicone spray, PTFE spray, rag

Repair difficulty: 2/10

Cups of tea: 2

Biscuits: 1 McVities Gold Bar

A mate of mine contacted me to ask if it was worth fixing his 6 year old Dyson DC40 and as always, I said yes it was.  A couple of days later, it was working again, like new.

FixItWorkshop, November’19, Dyson DC40.

The DC40 is still supported by Dyson and parts are readily available direct from them.  Problem is that, as my mate did, the price of some spares (although quite reasonable actually) can put some people off, which means that serviceable machinery can end up at the local dump, prematurely.  Which is a shame.

This is where pattern parts can help.  Often, aftermarket manufacturers will make spares for popular models and the advantage of these is that they are often much cheaper than the original part.  However, it’s not as simple as that.

I’ve fixed 100s if not 1000s of things and have used and continue to use a mixture of genuine original (often called OE or Original Equipment) and pattern parts for different reasons.  Assuming original equipment parts are the best, here are my thoughts, in no particular order, to help you if facing a similar dilemma.

In favour of pattern parts:

  • They can make a repair viable, financially
  • Parts can be available, long after original parts become obsolete
  • They can provide enhanced features that were not part of the original design

In favour of genuine/ original equipment parts:

  • They will fit exactly as the specification will be to the original design
  • They maintain manufacturers warranties, where applicable
  • They normally last well and perform as expected

As a further example, I will only fit genuine water pumps (on car engines) but will fit pattern air filters.  Water pumps must work within very exact performance tolerances whereas air filters, although important, don’t so much.  It’s a personal thing at the end of the day.

Back to the repair.  This Dyson wasn’t picking up dirt and the extension hose was torn, so a new hose was ordered from a supplier on eBay for under £10, a genuine part was over £25.  The hose just clicks out and in, so all that was required was a small flat bladed screwdriver to remove and refit the hose.  Nice and easy.

The next job was to sort out the lack of suction.  As with all Dysons with a problem like this, I always check filters.  As suspected, both filters were expired and needed to be replaced as they were too far gone to be washed.  Again, pattern part filters were available on eBay for under £7, genuine ones were much dearer.  All new parts fitted well and soon the vacuum cleaner was breathing easily again.

Another issue with the DC40 is the switch lever which diverts suction from the beater head to the hose, which was sticking on this machine.  A quick clean up and a small spray of silicone spray on all the moving parts had it all working again.

I always clean-up the beaters on any vacuum cleaner in for a service and this one seemed to have half a head of hair stuck in it, which would have impeded performance.  The hair was so bad, I had to remove the beaters (just one screw) and cut off the hair with a knife.

With all the remedial work completed, the Dyson ran well proving once again that it’s usually worth repairing, rather than replacing.

 

Minimum Cash for a Maxi Micro Scooter

A Maxi Scooter Gets a Refresh!

Before and after…

This is exactly the kind of job that I should have done with my daughter, but I had to do this repair in secret on this occasion as the scooter was to be a present for her.

Birthdays can be expensive times, but Dad is a shed-dwelling-repair-mad-penny-pinching fiend and it means that his children’s presents don’t need to be new. Take this Micro Maxi Scooter. £129.99 when new, second-hand for £10. Wheelie good value.

However, a £10 Micro Scooter isn’t going to be as fresh as one costing £129.99 is it, so time for a few service items and light renovation.

Make and model: Micro Maxi Scooter

Fault reported: Tatty, noisy wheels, brake rattles

Cost of replacement: About £129.99

Cost of parts: £16.68 (bearings, grips and tassels)

Hours spent on repair: 1

Tools needed: Allen keys, screwdriver, drill

Sundry items: Silicone spray, PTFE spray, rag

Repair difficulty: 3/10

Cups of tea: 1

Biscuits: 0 (I was being good for a change)

It’s amazing what a bit of spit and polish, mixed with a little elbow grease can achieve. A rattily, untidy Micro scooter that might have end up at the tip prematurely is now as good as new, thanks to some time spent and basic new parts, which only cost just over £16, or just over 10% of the value when new.

Rattily wheels

The four wheels on this model can take a pounding as kids take their scooters off kerbs and through puddles, just as they should. But the small bearings that allow the wheels to spin freely and smoothly can suffer with age and wear. Due to sensible design, the bearings fitted are readily available online and a complete set can bought for a fiver. After removing the wheels using an Allen key, the old bearings simply pop out using a large screwdriver and the new ones can be pushed in using your thumbs or a small vice. If you do this job yourself, don’t forget to clean all of the surfaces with a rag and something like WD40.

Tatty grips

The grips on older scooters can get mucky and after oil and sunshine have worked on them, they tend to suffer with discolouration and cracking. Again, the handle bars are a standard size and you won’t have any trouble sourcing the official replacements or aftermarket replacements

Noisy brake

The brakes on these scooters tend to become noisy with use as the small steel rivets rust and become lose with time. Although this issue doesn’t affect operation generally, it sounds horrible. On this scooter I decided to drill-out the existing rusty rivets and after a quick clean up, replace them with some alloy alternatives. These look better and will last much longer.

During this repair, I couldn’t do much about the chipped Micro Scooter logo, but even a new one would end up like this example after 5 minutes use!

A very satisfying repair and something any parent could do with their kids at home using basic tools.

Old school iPod Nano battery replacement

Apple really don’t want you to get into their products- but they’re not alone.

We have two Apple products in our house from the early 2000s; one iPod Nano 1st generation and the 1st generation iPod colour.

FixItWorkshop, Worthing, August’19, Apple iPod Nano.

Apple tech polarises opinion as it’s always premium priced and is quite locked-down to ‘Apple only platforms’.  Some people love the ease of use that their products seem to offer, others get frustrated with the lack of integration with other products.

Despite being an Android house, we keep the iPods as they are quite robust, but due to age, battery life has recently become an issue.

Make and model:  Apple iPod Nano

Fault reported: Battery not holding charge

Cost of replacement:  eBay, loads out there

Cost of parts:  £8.00

Hours spent on repair:  1

Tools needed:  Spudger, small flat-bladed screwdriver, soldering iron

Sundry items: None

Repair difficulty:  4/10

Cups of tea:  1

Biscuits:  2 (Custard Creams)

Let’s just get it out of the way now.  Apple really don’t want anyone opening up their devices and it was a wrestle to open up the casing, without snapping something (the iPod, not one of my nails or something).

The battery in the Nano is situated beneath the metal cover, which must be removed using a spudger.  A spudger is a small lever with a fine edge that can be used to gently open up small, usually plastic, push-fit, ‘clicked-together’ things.  Spudgers are kind of disposable and I always seem to break one on each job.  I must look out for a strong, stainless steel item.

Using the spudger on the Nano isn’t easy, since (as I later found out) all of the metal tangs located around the metal casing, dig in to the plastic face.  Trying the separate the two halves is a real battle and there’s a real risk of damage should you use too much force.

After a good 15 minutes of wrangling with the Nano, the casing popped off.

The battery on this model uses a small fly lead which is soldered to the main PCB, again more evidence to suggest that Apple had no intention of making the Nano’s battery replaceable by most users.  Extreme care had to be taken with the soldering too since the PCB’s components are so close and small, making it too easy to use too much heat, causing irreparable damage.

I took my time and was able to fit the new battery (push fit) and solder the connections OK.

The cover popped back on and fortunately, the screen lit up once more, when the menu button was pressed.  Phew. Tea time.

 

Imaginext Super Hero Flight Gotham City

Good thinking Batman, but I have a safety dilemma with a repair.

During a recent Toy Doctor surgery at a Dad La Soul/ Tot Rockin’ Beats event http://www.totrockinbeats.com/dad-la-soul I attempted a repair on a kids toy that I couldn’t get working in the two hours we had, so I asked if I could take it home to the workshop where I have more tools at my disposal.  Good thinking Batman.

The Imaginext Super Hero Flight Gotham City (catchy title for a toy) was much loved, but the flying bit (circled in red below) had stopped working and no longer did anything when switched on.  No fun without the flight bit.

Make and model:  Imaginext Super Hero Flight Gotham City

Fault reported: Not working

Cost of replacement:  £45.00 approx.

Cost of parts:  £0.00

Hours spent on repair:  About two hours- although to be honest, I lost count with this one

Tools needed:  Cleaning cloths, small fine file, soldering iron

Sundry items: Contact cleaner

Repair difficulty:  6/10

Cups of tea:  4

Biscuits:  10, maybe the whole pack, I lost count (Custard Creams)

The battery-powered flying thing on a weighted boom should fly about in a circular fashion and be controlled by the city platform, presumably by remote control from the main city bit.

Upon opening up the battery compartment, the problem revealed itself.  The previous batteries had leaked and the spillage has corroded the battery terminals.  No bother I thought, just a matter of cleaning-up the metal surfaces and we’d be back in business.  How wrong I was.  Even with new batteries installed, nothing happened, how very dissapointing.

No, it wasn’t going to be that easy and that was the theme for the rest of the repair.  Everywhere I turned, whether it was trying to open up the casings, inspect wiring or generally take something apart, I was going to be met with glued shut fixings and more problems.

Construction on this toy was very strange.  Surfaces on the casing were sometimes glued and screwed together, very odd, and I guess that method must have been used due to production time and cost saving.

The wiring between the flying bit and base checked out OK and the motor spun when I applied some charge briefly to the terminals, so that all seemed fine.

Upon opening up the gubbins where the switch was, the problem with the toy presented itself.  The mini printed circuit board had suffered from battery leakage corrosion and was shot.  Whatever it was meant to do was in the distant past.  So, this toy was for the WEEE skip, as there was no chance of getting a replacement.

Well, hang on a minute, we don’t give up like that do we.

I decided that I could make the toy work albeit without the printed circuit board by re-wiring the motor, using the existing loom and switch, so that the motor and therefore helicopter bit worked as it should.  This would mean that once the switch on the base of the unit was turned on, the helicopter would start and it would not be possible to turn it off without grabbing the moving base weight first.  It clearly wasn’t designed like that, but I had at least got it working again.

So, here was my dilemma:  Give up with something I couldn’t get a part for or get it working again, albeit with a removed (percived) safety feature, so that the toy could still be enjoyed.  I went with the latter as I thought that the danger was negligable.

Was I right?

 

 

Tone-deaf VTECH Singing Nursery Rhyme Book

VTECH kids toy gets a little help.

We love a musical singing book toy, don’t we.  They’re great for encouraging children to form words, read and follow a narrative.  We have a few of these and they’re all great fun, all the time the batteries hold up.

We’re not so fond of musical books when they seemingly start by themselves, at one o’clock in the morning, when there’s no one else in the house.  Very creepy.

Make and model:  VTECH Electronics Singing Nursery Rhyme Book

Fault reported: Poor sound quality

Cost of replacement:  N/A

Cost of parts:  £0.00

Hours spent on repair:  About 10 minutes

Tools needed:  Small file, cleaning cloths

Sundry items: Contact cleaner

Repair difficulty:  1/10

FixItWorkshop, Worthing, July’19, VTECH Singing Nursery Rhyme Book.

This toy was a hand-me-down and had enjoyed a few years of use already, before it came in to our household, but it was in good condition and still has many more years left in it yet.

Recently though the singing emanating from the book was becoming a bit off-key and to be frank, rather than bringing joy the noise coming from the toy was enough to induce nightmares.  I keep a ready supply of rechargeable ‘AA’ batteries in this house and after popping out the old ones, the new ones fitted, I assumed all would be well, but not so.

Despite fresh power, the singing was still horrible and wobbly.  A quick test of both sets of batteries (old and new) revealed that the original batteries were fine and that something else was at play.

Time to delve a little deeper.

Galvanic corrosion can occur when two different metals in close contact with each other, chemically react.  The corrosion forms a barrier, in this case between the electrical contacts of the toy and battery to form a resistance.  This means that the toy, with the corroded contacts, wouldn’t get the full power it needed.

There was some minor corrosion on the contacts that needed a quick clean with some cloth and contact cleaner, something I keep on the shelf for such an occasion.

This did the trick and with the original batteries fitted, the toy was back on song once more, ready for another performance.

Kenwood FP220 easy fix

An easy fix for a change

Every now and then an enquiry drops into my inbox where my heart sinks.  It sinks as I know that many products on sale are poorly supported for specific spares which means that when the product fails, it can be impossible to repair.  But sometimes, just sometimes, I’m surprised!

Make and model:  Kenwood FP220 Food Mixer

Fault reported: Mixer not working when main jug used

Cost of replacement:  £120.00 (equivalent new machine)

Cost of parts:  £17.69 (plus my time)

Hours spent on repair:  About 10 minutes (test and cleaning)

Tools needed:  None.

Sundry items: 1 X Grimex cloth

Repair difficulty:  1/10

FixItWorkshop, Worthing, June’19, Kenwood FP220.

The mixer was a good quality item which had cost over £100 when new and upon inspection, the mixer has failed due to a single component, the main jug.  A little clue from the owner that the blender attachment (not pictured) worked, but the jug didn’t, set me off on the right track.

The mixer features a safety mechanism which is designed to prevent the main drive assembly spinning accidently, potentially with a cutting tool, if the switch is operated without the mixer jug attached.  Many mixers of this type feature such a device.

The FP220 features a double-armed safety mechanism which means that the jug must be fully engaged in the mixer base, with the lid in the correct position.  It’s an unobtrusive and fail-safe design.  A part of the jug’s base, made of a composite plastic, had sheared off, so the jug could not attach to the mixer properly.  The safety device had worked as it should.

At first, I thought that there was no chance of obtaining a spare jug, but after a bit of Googling, I found a brand-new replacement jug, in the right colour, from Sussex Spares (via eBay).  It soon arrived and fitted perfectly, which allowed the machine to work again, once more.  The old lid was still serviceable and fitted the new jug without problems.  I recommended that owner keep the old jug for spares as the handle and drive coupling were still servicable and might come in handy if the new handle gets broken.

After a quick clean up and test, the machine was ready to make Victoria Sponges again.  It just proves that with a bit of research, even seemingly unrepairable items can get a second chance.

Dim Lumie Bedbug

Lumie bedbug glows once again.

A short repair tale about a little bedtime bug.

A friend mentioned that their son’s Lumie Bedbug lamp was intermittently working and that it was shortly going to be visiting the bin if it didn’t buck its ideas up.

Er, no I said.

IMG_20190524_142951
FixItWorkshop, Worthing, May’19, Lumie Bedbug.

The bug night light was meant to glow orange, once switched on, but it only lit up when the cable was wobbled about.

The power connection on this model is a standard USB (B) connector, the ones commonly used to charge Android phones.  If the power lead was faulty, it would be easy to find a suitable replacement.

The bug comes apart by removing the silicone outer layer and releasing the tangs holding the two halves of the bug together.  One screw holds the PCB in place and once removed, the whole thing comes to pieces.

The USB socket was a little out of shape, presumably from some rough handling.  A quick nip with a pair of pliers and it was back as it should be.

The plug was also a little out of shape, but with a bit of careful re-shaping, it fitted the socket perfectly.

Once reassembled, reconnected and powered up, the bug glowed without flickering.  Result.

Cost of replacement:  £50.  Cost of repair:  One tea and one custard cream, that I made myself.
