Should there be water sitting in pre-chamber of SMART Hotpoint Washing Machine

An update: i did an auto (service) clean on the hotpoint. Added vinegar and baking soda - was a long wash and assume it was hot. temp The smell seems to have gone but it has only been a day. I shall keep monitoring.
 A small piece of fabric came out of the wash (it was a piece of a garment obviously stuck in the machine)- i wonder if this was the cause of the smell - I guess I'll know within days -  I had no idea this piece of fabric was in the machine as no error code appeared to show a blockage.....you've all been so helpful - thanx

Is your drain pipe fitted so it's like an upside down U? With the top of the U close to the top of the machine? If not then what will happen is when the pump stops any water left in the pipe drains back into the bottom of the washing machine and goes stagnant , hence the eggy smell 

Eggy smell is the smell of stagnant water

That's right it is a sign of stagnant water in the pipe work. As above regarding the U-Bend, does your drain pipe have this? This link may help.
