The power keeps cutting out after a few seconds
The battery is fully charged.
We press the trigger button and the the hoover works for a few seconds and then stops. It does this consistently
If your vacuum suddenly turns off during use, see the Dyson DC58 Shuts Off While In Use problem page for possible causes and solutions.
I suspect it is the battery protection circuit cutting in. This circuit monitors the battery voltage. After the motor is first started, the battle voltage will drop due to a load of starting up the motor. The circuit allows a second or so for the voltage to recover. If the voltage does not recover in this period, it shuts down the motor on the assumption that there is a fault that is drawing too much current and will cause the battery to explode into flames. As batteries age, their internal resistance increases and they take longer to recover from the startup load. Things like cleaning the filters etc. will reduce the startup load and this will temporary solve the problem. As you can see from the first few seconds the motor runs OK, there is nothing really wrong with the machine (or in fact the battery except that it is slowing down a little in its middle age.) The real problem is the design of the protection circuit. It is too simplistic in monitoring approach and is causing thousand of Dysons owner to replace their batteries when they still have years of use still left in them. Shame Dyson, shame!
Most likely a blockage problem. The motor is set to turn off if uses too much current for protection. I would clean the filter and dismantle any accessories, espically any spinning brushes, as these can get clogged easily.
Same problem. It seems to involve the button itself. Sometimes I can move my finger to a slightly different area of the button and it stays on a little longer. Very frustrating. I love my Dyson 35 but want to through it out the window when it acts up.
The filter needs cleaning. Try running it without the filter in. If it works fine, the filter needs cleaning, even though it looks clean. This happened to me.
Bought the very first hand held Dyson had the same problem was told there was a fault with the on of button as out of warranty they gave me a small discount to purchase the new model as the problem had been rectified bought it ,out of warranty same problem never a hand held Dyson again
We had the same issue with a relative new (under warranty) received battery.
Cleaned the filter, but it intermittently did shut off when using.
What helped was removing the cyclone from the motorunit. Follow theses steps till step 7; Dyson DC58 Cyclone Replacement
Then remove the filter if not done already and let the cyclone soak in warm water with some soap.
Flush the cyclone, until water comes out clean. Let it dry and re-assemble.
Worked for our DC58
I phoned Dyson and told them about it. They told me to remove the filter and clean the metal contacts. This solved the problem for me.
“&&^& DYSON!!!” Paid a lot of money for a Peace of $@$* product!!
My Dyson absolute works fine on low power. But as soon as I press the button for full power it cuts out.
I have found that putting it back on the charger for a few seconds makes it usable again on low power. But it will cut out again if put on full power.
I bought this Dyson because I was impressed with the power. But it was very short lived.
Very disappointed in Dyson and will not be buying again. They need to sort this issue out or stop selling them !
Forgot to say…my son bought one and has the very same problem.
My Dyson , when fully charged, cuts out after 20-30 secs. Putting it back on charge for ~10 secs usually allows it to run normally afterwards. The cut outs are irritating and does seem to be an issue that Dyson could address.
I have a Dyson Animal and after 6 months it started to cut off a lot when using the power head. After reviewing all the comments I decided to check it for myself. We use it mostly for carpet cleaning and on the power head I noticed it needed some cushion so it won't drag on the carpet. After placing some cushion it works great again. I would use velcro type cushion that I cut into strip and stick it on the power head that touches the carpet. Hope this helps others.
If it’s cutting out then you have to take it apart and clean everything with lab-quality alcohol (Isopropyl Alcohol Lab Grade Rubbing IPA Disinfectant).
Pretty sure it is what the fellow upthread surmised, it is some kind of battery protection that is based on voltage sensing or heat sensing that goes awry. Don’t think a new battery or cleaning will help. Best thing is to buy a new vac rather than waste money on a new OEM battery which is close to half the price of a new unit of an older model on clearance.The non OEM batteries use cells that have been rejected by quality control and they are assembled haphazardly without any control circuitry (I opened one up) to achieve the low prices, I would not trust them to last very long.
