Washing machines, dishwashers and tumble dryers have electro magnetic motors or inertia driven by electro magnetic power fuels source electric current.
Your best bet is to contact hotpoint but don't expect a solution that easy as it could be lose connection somewhere in the circuit is you have to 'kick start it'.
They may want to a circuit test to rule in or out a lose connection/switch toggle etc.
