Dyson Supersonic Weak Airflow or Loud Noise

Assessment £4.99

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

Signs you need this repair

  • Airflow much weaker than it used to be
  • Rattling, grinding or whining noise
  • Higher pitched than it was
  • Takes much longer to dry hair
  • Noise changes when you tilt it

Weak airflow and a new noise both come from the same part of a Supersonic: the air path and the motor that drives it. At one end it's a filter and airway clogged with hair, dust and product. At the other it's a worn motor or a damaged impeller. From the outside they sound and feel the same, so this is one fault I won't put a single price on before I've opened it.

So it starts with an assessment. You pay £4.99 when you book, which covers the tracked return postage. I open it, check the airflow path end to end, measure the airflow against a known-good Supersonic, and test the motor for resistance, free running and bearing condition. Then I send you a quote, and nothing else happens until you say yes.

Most of the time it's the airflow, and that's the £49 service and deep clean. If the motor or impeller has failed, the repair is from £109. Go ahead and the £4.99 comes off the price, with a 12-month warranty, a PAT safety test and insured tracked return postage included. Decide against it, or if it can't be repaired, I post it back and the £4.99 covers that postage.

Try one thing first, because it's free. The filter is the fine mesh sleeve around the base of the handle. Slide it down, brush it out thoroughly and see if the airflow comes back. A lot of dryers that sound like a dying motor turn out to have a filter that hasn't been cleaned in a long time.

Frequently asked questions

Why can't you just tell me a price?
Because the same symptom can be a clogged airway or a failed motor, and there's no way to tell from the outside. A £4.99 assessment finds out, and it comes off the repair if you go ahead.
Is a noisy motor worth replacing?
Often, on a dryer that cost several hundred pounds new, but not always. Motor repairs are from £109, and if I think you'd be better off putting the money towards a replacement, I'll say so.
What if it turns out to be just the filter?
Then it's the £49 service and deep clean, the £4.99 comes off it, and you pay the difference. I'm not going to invent a bigger job than the one you've got.
What if I decide not to go ahead?
I post it back. The £4.99 covers the tracked return postage, so there's nothing more to pay.

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 post it back, and the £4.99 you paid covers the tracked return postage. If you'd rather I recycled it responsibly, I'll refund the £4.99 in full.
