i have just used this site to clear a fault on my old (and reliable) dyson cr01. Im chuffed to bits that this site has helped me - i cleared the F4 fault within 10 mins of reading the information. One question - after i cleared the fault it came up with the code 3422f4f1f2v127 - can anyone tell me what this relates to?

many thanks - this site is GREAT!!

if the below info doesn't fix the problem,can you tell us the code the wm presented before you cleared the code.if it was f4 or f2 then replace the outer door switch ,if you get the same error then you will have to replace the pcb card.door switch not a costly repair,but pcb is.better getting dyson out 99 quid all in.

try clearing the codes again,this time with both inner door and outer closure closed.you have accessed the eprom with both or one door open.
