Hello, I am not sure what part I may need but my tumble dryer is tripping the RCD after running for a period of time and need some advice. 1) The pump is working as water is being collected 2) The condensor unit has been cleaned and free from debris 3) The drum is turning freely and so motor is ok 4) The machine is getting hot so the heater is working 5) The RCD does not trip straightaway and it appears to me that the machine may be overheating and this could possibly be causing RCD to trip after about 30 minutes or so. The time varies as it depends whats being dried and how much load there is. For example Towels create a lot of steam and heat and this will trip after about 20 minutes. The rear of the machine does feel very hot If its the mains filter would this not trip RCD immediately ? Could you possibly suggest what may be wrong
