Erratic GHD hair straighteners

Straight GHDs

GHD hair straighteners are a premium product which retail for a minimum of £100 in the UK.  However, over time they suffer from common annoying faults which cause owners to condemn the set they have.

This set of straighteners presented ‘as working’ when first switched on.  After warming up, hair straightening temperature was reached within the normal time.  However, after 5 minutes of use, the temperature reduced and failed to re-heat in a reasonable time.  Leaving the straighteners to cool completely would effectively reset the problem, only for  the cycle to repeat again.

GHD faults are well documented on YouTube and the fault turned out to be a faulty thermocouple or thermofuse, which should regulate the temperature and cut power in the event of a fault.  They do however wear out and this set of straighteners was no exception.

After dismantling, the thermal fuse was replaced for £2.70.  The whole job took half an hour and saved the owner nearly £100 on a replacement.

A Dyson DC33 gets treated to a new motor

Conked out Dyson DC33

This Dyson presented with a pretty terminal case of ‘no go’.  The owner had run this relatively new machine in to the ground with little maintenance so it was little wonder what happened next.

Whilst in use, the machine spectacularly went bang and tripped the main fuse board of the house.  The noise and following smell was quite something I was told.

The owner had nearly rushed out and bought a new machine and was budgeting between £300 and £400 for a replacement.

FixItWorkshop, Worthing, Feb’17. Dyson DC33 motor replaced

I was glad I could help since I was fairly certain I knew what the problem was without seeing it.  After giving the cable, switches and casing a visual inspection, it was time to delve deeper.  The filters were in poor condition and the general smell of it indicated that overheating had been an issue, probably leading to premature wear on the motor.

With the motor out, the true extent of the damage became apparent.  Both motor bushes had worn away to nothing and part of the brush holder had broken up inside the motor, probably while it was running, causing the noise.

I suspect that the owner had ignored the warning signs of burning smells and occasional cutting out (as the thermal overload circuitry performed its fail-safe role).

Being only a few years old, the owner had a couple of options; either replacing the faulty part with a genuine Dyson replacement (a very reasonable £40) or pattern motor kit with filter pack for under £25.  The owner chose the latter on the basis of the machine’s age and the fact that both filters in the machine were also ruined.

The job took an hour, including testing before the machine was back performing its cleaning duties once more.

A note to all vacuum cleaner owners (that don’t take bags):  Keep your filters cleaned every couple of months or so.  Your machine will last much longer if you do.

Lazy Dyson DC04 Vacuum Cleaner

Dyson DC04 brush problems

Sadly, I’ve seen loads of these older Dyson machines at the tip in recent years.  I suspect, with a bit of fettling and cleaning, they could be brought back to rude health.

This one was one a high-mileage example and needed some tinker-time to get it back to a serviceable condition.

It was working of sorts, but failing to ‘pick-up’ as well as it used to.  It turned out that the roller had two problems.  The main bearings were worn, making a squealing noise and the brushes had worn low.  This part used to be available from Dyson, but due to the age of the machine, they quite reasonably, stopped selling them.  However, the net is awash with reasonable pattern parts for Dyson machines and while I tend to stick to original equipment wherever possible, a replacement roller from ebay for under £10 was a reasonable choice for this 15 year old vacuum cleaner.  A replacement Dyson vacuum cleaner would be at least £250 for a basic model at time of writing.

Just a note on Dyson machines:  Having studied the company at school and following their progress for a number of years, they seem to be a firm believer in providing accessible and affordable parts to keep their products alive.  They’re an excellent example of a company that truly believes in product sustainability.

Kenwood Chef Repair

Kenwood repair in Worthing, West Sussex

Smelly Kenwood Chef A901

FixItWorkshop, Worthing, Jan’17.  Repaired Kenwood Chef A901

This Kenwood Chef developed a nasty little problem. The failure smelled expensive and the Chef even puffed out some smoke when it began to fail, it would operate, but noisily and badly, so it to the workshop it had to go.

It was in decent overall condition and has loads of accessories, so definitely worth saving since a new one is over £300 new.

Since the speed control circuitry is a common failure on models of this age, it seemed sensible to start there.  On this unit, access wasn’t a problem and the issue was quickly diagnosed.  Both capacitors had failed (spectacularly)  and one of the resistors had become weak by about 20 Ohms or so.  Repair kits are readily available online for those who are willing to save these excellent machines, so after removing the faulty components, new items were fitted.

Another little annoying problem with the Chef, was the main drive belt.  It was intermittently rubbing the main plastic body of the unit, making a horrible sound and melting some of the casing (only cosmetic).  The motor mounting spacer had compressed on one side causing the belt to not run correctly.  This was fixed with a small washer to correct the belt’s alignment.

With a little bit of grease, WD40, Brasso, contact cleaner, repair kit and washer, the whole job took a couple of hours (including fettling time) and cost me under £8.  Definitely worth the effort considering the price of a replacement Chef.

Here’s a picture of the new components fitted in situ…
