Your machine is stuck in 'engineers test cycle' which is activated by a specific combination of button presses and is used by Hotpoint engineers to perform a very quick cycle test after repairing a machine. You will very likely need to call Hotpoint directly for advice on how to cancel the cycle.
It will be a combination of button presses on your machine options but each model varies.
They SHOULD give you this advice over the phone for FREE ! ! !
