Please can you help? I have a Hotpoint aquarius WF620 that overheated!?

My Hotpoint aquarius WF620 Washing machine overheated to a scary temperature. It was so hot steam was bellowing from the washing powder dispenser. I turned it off to cool down and any time I put it back on it shows 'Test' and begins filling with water. The error code F-03 also appears and it wont drain the water or do any other programs after switching the dial. I tried the advice of getting rid of test but it did not work! Is it totally dead or can it be salvaged?! Thank you.
