Beko DRCS68W not entering reset mode?

Hello everyone, I am having issues with my Beko DRCS68W condenser tumble dryer. It started when the drum got stuck last month and broke the belt. I cleaned out the lint and replaced the belt but it wouldn't heat up inside the drum. I then replaced the heater element with a brand new one as the old one does look as though it probably overheated when the drum stuck. I have since put it all back together and it still doesn't heat. I have tried the reset button on the thermostat of the heater but that didn't do anything, there seemed to be current running though the heater but not the thermostat. Used a voltmeter for this, not my tongue... I have since tried to set it into reset mode by setting it to delicates, holding down the buzzer/cancel button for 10 seconds but it just stays the same with only the drying light illuminated. Is there any other way to enter the reset mode?? Can anyone help me to try and get this heating again as that is all that remains before I have to spend £60 on a Beko callout charge.
