You need to note if there is an error, such as an E2 error. Check your display for an error number first.
I am assuming your model is younger than my ADP8226 integrated. Either way, these are typically SMEG rebadged units.
If the error is showing E2, then it could be a flood activation alert, or a fault with the circulation pump.
A circulation pump is expensive to replace, typically about 150.00 for the part.. Check out the Uk whitegoods website for details on spares:
