Urgent help please - re: slow cooker

[Sparkler]

I've just prepared a schwartz beef casserole. Fried it and have put it into my slow cooker with all the recommended ingredients for oven cooking.
Do I need to add extra water for the slow cooker?

Sorry to be a dunce - I'm no Delia Smith

Damn active convos is moving fast this afternoon.

less water in a slow cooker than in a conventional oven

so no

in fact you might need to spoon a bit out

Thank you. xx
