beko is70c tripping rcd box?

Moved house on Sunday, dryer worked fine in old house. Used it for 2 cycles here with no probs, then ran it the same time as the dishwasher... Bam. Rcd tripped.

Now everytime I put power to the damn dryer the rcd trips. So infuriating. With 2 kids and one on the way, I need help. I can't afford expensive repairs or a new dryer.

Any advice welcome, I'm a blonde female who only uses screw drivers to open packages, need to keep it seemples! ;-)
