Dyson V15 Detect: Dyson V15 Detect stops after a few seconds with no indicators

Thu, 12 Mar 2026 08:26:27 -0700

I've had it for nearly 2 years. The problem occurs when I press the trigger—it runs for a few seconds and then stops (with its signature "wooump" sound). It repeats this 2-3 times before eventually working. However, now I can't get it to run for longer than a few seconds, even after several tries.

I’ve changed the filter and cleaned everything I can access. In some forums, I’ve read that it might be an issue with the "main body," (whatever that means) while others suggest it could just be a cracked trigger, which should be an easy fix.

Dyson V15 Detect: Suddenly battery problem on Dyson v15

Sun, 27 Jul 2025 08:14:11 -0700

Hi,

I have a Dyson v15 detect and it worked great within the warranty. But few month later it just turns off and did not start again. No LED function in battery, not in starting, not on loading. I measured the small connectors from the battery itself and getting 24v. The bigger connectors do not have any voltage, when pressing spring loaded plastic pin and also when not. So for me it looks like a defect battery. I ordered some spare part from AliExpress which i am able to load and when i Insert it, the display turns on, but i cannot start the machine.

So i measured the voltage on that alternative battery and it is 28V on small pins and 12v when spring pin pressed. On big connectors I get ~0.24v. when pressing the spring pin it changes, sometimes to 28.5V, sometimes it is just struggling and went back to 0.24v.

I don't know the expected behavior. Have someone here a working original battery and can measure the voltages? Between the small and big connectors with and without pressed spring pin.

I tried to film it. For me the reactions of the battery for pressing the Pin are stupid. Is my alternative battery also defect?
