Dyson Supersonic Cable Repair

£79

No fix, no fee · 12-month warranty · Insured, tracked returns

Signs you need this repair

  • Only works when you hold the cable at an angle
  • Cuts in and out during use
  • Works if you wiggle the lead near the handle
  • Visible kink, split or scorching on the lead
  • Stopped working after the cable was caught or pulled

If your Supersonic works when the cable is held one way and stops when you let go, you've already found the fault. The lead has broken internally — and this is the single most common failure on these dryers.

It happens because of where the cable lives. It gets wound round the handle for storage, pulled out of sockets by the lead rather than the plug, trapped under the dryer on a shelf, and flexed hard every single time it's used. The conductors inside are fine strands of copper and they fatigue. Usually the break is within a couple of inches of where the lead enters the handle, though it can also go at the plug end.

The outside of the cable often looks completely fine, which is why this fault confuses people. The insulation is intact. The copper inside it isn't. A broken conductor that intermittently makes contact is also why it works some of the time — and why it will get worse rather than better.

This one matters more than most. An intermittent connection in a lead carrying around seven amps arcs where it's broken, and that generates heat inside insulation you can't see through. It isn't a fault to carry on using around. If yours is doing this, stop using it.

I replace the full cable assembly with a correctly rated lead, not a repaired one — a spliced mains cable on a handheld appliance isn't something I'm willing to send back to a customer. Reassembled, run-tested, PAT tested, and returned insured and tracked. £79 covers everything.

Frequently asked questions

Can't you just repair the broken section?
No, and I wouldn't want to. A joint in a mains lead on an appliance that gets flexed constantly is a weak point waiting to happen. The whole cable assembly gets replaced.
Is it safe to keep using until it's fixed?
No. An intermittent break arcs internally, and that generates heat inside the insulation where you can't see it. Stop using it and get it sorted.
Mine has a scorch mark near the plug — same repair?
Same repair, but tell me about the scorching when you book. It can mean that end has been running hot, which is worth looking at properly rather than just swapping the lead.

About this service

How does your mail-in repair service work?
Three steps: book and pay for your repair online, post your item to me using the packing instructions I email you, and I repair it, test it, and send it back tracked. You'll get updates as it moves through each stage.
What is your no-fix-no-fee promise?
Payment is taken upfront at booking. If I can't fix your item, there's no repair fee — I refund what you paid, less £4.99 return postage to send it back to you. Assessment bookings work differently: the £4.99 covers return postage and comes off the repair if you go ahead, but isn't refunded if you decide not to or it can't be repaired.
Do your repairs come with a warranty?
Yes. Every repair carries a 12-month workmanship warranty against the same fault returning. If it does, I'll put it right.
How long will my repair take?
Most repairs are completed within 1-3 working days of arrival, then posted back by tracked post. If a part needs ordering, I'll tell you as soon as I've diagnosed it and give you a realistic date. Diagnostic-led jobs take a little longer if I'm waiting on your approval of a quote.
How do I package my item safely to post it?
I send clear packing guidance when you book. In short: wrap the item well, use plenty of padding, and a sturdy box — the return leg is insured and tracked, and good packing on the way in protects your item too.
Where do I send my item?
Your postage address is included in the confirmation email after you book — you don't post anything until you've booked, so your item is always matched to your order.
Do you cover the whole UK?
Yes — I run a mail-in repair service, so you can send your item from anywhere in the UK. There's nothing local you need to find.
What if my item turns out to be unrepairable?
I'll tell you honestly and, where the fault allows, offer an alternative. If I can't fix it, there's no repair fee — I refund what you paid, less £4.99 return postage to send it back to you.
