I've got a Dyson V7 Motorhead Plus - the motorised brush doesn't seem to be working. It doesn't matter if it's with or without the wand - the blue light comes on by the battery, but the motorhead doesn't power up (nor does the vacuum itself, with the head attached). With a non-motorised attachment, it works fine, with or without the wand.
Is it likely that I'll need a new motorhead, or is there anything else I should check before going ahead and buying a replacement one? Just found it a bit odd that the light remained solid blue with the motorhead attached, rather than red, despite the vacuum not powering up at all.
