how can i fix my Beko dcrs68w ?

My partner trapped some clothing in the door of the Beko drcs68w dryer and this jammed the drum eventually I spotted this and released the item, unfortunately it was too late the motor was still working but I suspected a damaged belt.

Having stripped the dryer down my suspicions were confirmed the belt was broken,I soon purchased a new belt and following installing it I turned the power back on.

The lights came on as normal and the drum turned 1 full cycle but stopped,I turned power off then on again and it did the same. I again turned power off following this I have no led lights on the front panel and no response from the dryer.

Just seems weird as the drum compartment light is on.

It would be much appreciated if anyone can help?
