Plaster will have blocked the filters. Unless youve accidentally sucked up
wet stuff, the cyclones are probably okay.

I don't think so as it runs fine without the canister attached and I can
hear the shut off valve operate when I replace the canister with no
hoses attached.

The only filter appears to be a fine stainless steel mesh on the
canister which I have cleaned.

So to re iterate; it seems the machine senses a depression across the
canister and triggers the shut off.

I note Dyson clearly state this device should not be used to suck up
fine dust, plaster, sawdust, soot or flour but too late for that and a
new canister of cyclones is over 70 quid.
