This video shows how to replace a damaged changeover valve on a Dyson DC40. It was working OK from the hose but not sucking very well when in carpet cleaning mode. The problem turned out to be a ripped changeover valve. I bought a replacement from Amazon for £6 (Dyson P/N 922625-03 "COV HOSE ASSY"). It's fairly easy to replace and only took about 10 minutes. The full video of the repair is shown below. You'll need a Torx T8 and T15 screwdriver bit.
