Smeg Dishwasher DI6012 constantly draining

[Dave McC]

Hi,
I have a common problem with my smeg built in dishwasher which is constantly draining even if the door is open. Lights 1 (flashing) and 5 (on) is the error I get. There is no water in the base and I cannot see anything else I can try. I can't see any float that is stuck. There is no sponge in the bottom of this machine like some other posts suggest. Just a small piece of polystyrene in the center which freely moves.
I'm stuck what to try next so thought I'd post before resorting to a new machine.

Thanks
Dave

Hi,

Did you sort this out in the end. I am having exactly the same kind of problem with mine (DI521)
