Tricity Bendix dryer TM310W light is on showing tank full?

your pressure switch is clogged with soap/powder residue,unplug your machine & remove the top,look down the side of the drum(same side as programmer)you should be able to see a clear pipe (6mm/1/4")diameter this run's from the drum to the pressure switch,switch is located by the programmer, remove this pipe from the switch & blow down it,this should push the residue away,refit pipe & top(this will only be a temperarily repair,put you machine on a short programe to see that it is o.k ) if so you will need to remove the other end of the pipe, retained by a screw,and wash the residue out,if this does not work,it could be the pressure switch it self.try appliancehelp@ntlworld.com for part's.hope this help's
