My machine turned off while I was vacuuming Large items may block the tools or nozzle. If any part becomes blocked or the filter needs washing, the machine may make a pulsating noise and then automatically cut-out. For help resolving this issue please see the link below on how to remove a blockage. How to clear a blockage My machine displays an LED lightJump to: navigation, search Remove large Torx retaining screws, arrowed Unscrew the tiny Torx screw, unplug and remove PCB - Link between 1 & 3 Hall-effect device removed and linked out with blobs of solder The Dyson DC16 Root 6 portable vacuum cleaner intermittently cuts out after a few seconds use, the red light comes on (indicating a fault mode?). It's as if the battery is flat, but this happens even with the battery fully charged. It is intermittent, sometimes it works fine. It appears that the hall-effect device [a transistor that detects changes in a magnetic field] is intermittently failing so the cleaner logic thinks the filter has not been fitted and goes into fault mode.

This is a field-fix, not a repair. Remove the faulty hall-effect device and permanently bridge the device so the unit thinks the filter is fitted, even if it's not. If you want to replace the device it is an Infineon low-power Hall-Effect switch, TLE4913, available from most electronics component suppliers. A quick Google should find you one easily. Do not even attempt to repair this yourself if you are not comfortable removing surface-mounted semi-conductors and attempting soldering on a sub-miniature scale. However, if the unit was like ours, unusable, you probably have nothing to lose. Very small soldering iron (I scored low on 2 & 3 and still managed a success!) Strip the unit down to the panel that the battery was mounted on by un-clipping all user-removable items Unscrew the two large Torx screws (arrowed) Unplug white and set connectors from the PCB Remove the tiny #6 Torx screw retaining the PCB Carefully remove the PCB Remove and discard the faulty hall-effect unit

The easiest method is probably to heat each connection individually and gently prise each leg away from the pcb Link out connections #1 & #3 I found it easier to build up a blob of solder than to link with wire - do whatever you find easiest Re-connected to PCB & battery and test - it should now work without the filter connected Oddly the same symptoms seem to occur if the unit needs emptying and it cannot 'cyclone' - I'm not certain how that can be, but emptying it appears to solve the problem! Sometimes a similar fault can occur if the filters are badly blocked. Replace or wash out the filter to prove the fault. Allow the filters to dry properly before using the unit properly or it will clog up. Visitors have reported similar symptoms being caused by a faulty battery. Check by substitution if possible as the replacement batteries are very expensive. The output of a fully charged battery should be around 21.5 volts. This came to me from one of our Belgian visitors:

There can be another problem on the Dyson DC16. In the battery pack is a small temperature control. vacuum cleaner blows fuseIf the battery become too hot, it will cut the power. car vacuum cleaner torontoI remove that part and soldered the 2 wires together. mini canister vacuum cleanerThe Dyson wasn't charge anymore (the red light flash). I bought a new battery pack and all is OK now. There is nothing indicated on the micro temp.control! I measured the voltage from each battery and that is OK, but I think the temperature control must be fault. What's better than a Dyson handheld vacuum cleaner (hoover) DC35 Animal (purple) stops after a few seconds and makes a funny noise Machine cut out during use Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat.

This usually happens because the filter needs washing or your machine is blocked. If your machine turns off on its own, unplug it and leave it for at least an hour to cool down. Remember to check the filter and look for blockages before re-starting. Any non-domestic use may adversely affect the filter performance such as vacuuming up drywall dust. How to wash the filtersI love my Dyson DC59 Motorhead cordless vacuum. It’s so very convenient to vacuum anywhere, anytime. However, it has one drawback – at least, it’s a possible drawback if you don’t know how to fix it. Sometimes, my Dyson DC59 cordless vacuum will start pulsating off and on constantly while I’m vacuuming with it. I’ve encountered this problem on two separate occasions, and the fix turned out to be something different each time. The first time, I emailed Dyson support, but I’d already tried everything in their response. I’d tried everything Dyson’s website had to offer before contacting support.

Here are five things to try if you encounter a problem with your Dyson cordless vacuum pulsing off and on. Mine is a DC59, but these tips may apply to other, similar Dyson cordless vacuums. The only tools you’ll need are a coin such as a nickel or quarter, plus something long and skinny like a flat-head screwdriver or a butter knife. This post may contain affiliate links; please read my disclosure here. Ensure that the power cable did not partially disconnect from either the wall or the vacuum while it was charging. It’s remotely possible that the rechargeable battery has stopped charging, but it’s more likely that it’s somehow not getting plugged in properly or it’s getting knocked off kilter when it’s charging. The vacuum can easily fall over and pull the plug partially out of the wall. Flashing blue lights on both sides of the motor indicate that the battery needs charged. If you find that the battery isn’t charging at all and you need a new one, you can buy one online.

You can also find a replacement Dyson charger for DC58/59 Motor Head at this link. If the MAX button lights up and flashes when your Dyson cordless vacuum keeps pulsating on and off, hold the power button and depress the MAX button to turn off that function. You may have to try a few times to get the hang of it. I had this happen to me, and I couldn’t for the life of me figure out how or why MAX had gotten activated. I’m also not sure why it’s there if it causes problems when it’s turned on. Try the Dyson vacuum without the long sweeper attachment and see if you still have the problem. If not, then you may have a clog somewhere in that attachment. Look down through the tube with a flashlight. Check to see if there are clogs on the sweeper end or if the roller is tangled up in fibers. It’s easy to use a coin to remove the roller assembly and clean the whole area thoroughly. It can be challenging to completely empty the dust bucket sometimes. It’s a minor inconvenience for me, since I just use an old butter knife.

Even so, debris can bunch up in hard-to-reach places. Fortunately, removing the dust bucket for more thorough cleaning is pretty simple. Simply pull the red release tab once to open the flap and a second time to detach the dust bucket. If you think you could use a replacement, you can buy a Dyson Bin Assembly, DC58/59 at this link. You know that blue cone-shaped filter you’re supposed to rinse monthly? If you’re like me, you might pull it out occasionally, see that it looks clean as a whistle and put it back in. I’ve found that you really do need to rinse the filter regularly, even if it looks clean on the outside. Follow the vacuum’s instructions to rinse it under the sink for a minute or two, squeeze out the excess water and let it dry at least 24 hours. When it’s completely bone dry, return it to the Dyson. If you can’t get the filter completely clean or it looks worn, you can pick up a new one for about $16.95. Here are some additional replacement parts you might want to consider at some point:
