HI again i tried timed heating for longer and it still glows red hot for about 2 seconds and then the elements cut out ,there are 4 elements within the housing 2 measure 20 ohms and 2 measure 47 ohms.the top cut out or thermistor measures 20 k ohms
and the bottom one is s/c i have thoroughly hoovered out all fluff from element and filter etc.the top cut out is addressed by 2 x red wires and the bottom by 2 blue wires .my guess is that the elements are all ok!the drum rotates and there is a blower but i do not know why the elements are not on ?can anyone help?

assuming you haven't connected the wires to the heater in the wrong place (thin wires to the sensor that reads 20k) then i would check the wire that goes down the right hand side at the front.there is a connector there and these have been known to pull apart.only real way to get to it is to remove the whole inner drum unless you do a continuity test on it
