As soon as I turn on the poer in the caravan the toilet pump starts working and flushing the toilet. I had to remove the fuse to stop the pump. What could be causing the problem?

Could be the flush button micro switch ( if it has one) has stuck in on position. or if standard on/off toggle switch could be faulty.
