Thanks that's interesting. Had a lot of problems with powder staining clothes myself. Still trying to get to the bottom of that one. Take back cover off and use multimeter on the heating element like the man says below. If broke you won't get a reading. Recommend taking the top off with the plug out also and checking all plugs are secure on the module and especially the programme selector which can fall open and cause an open circuit with the vibration. Mine did.
