How can I fix my D41 dishwasher?

I have a brand new Indesit D41 dishwasher, unfortunatley it has been in storage (in original packing and totally unused) for over 2 years and therefore Indesit will not deal with any problems. Its been plumbed in for the first time and turned on - after a few seconds the first error light starts to flash, according to Indesit this means there is water in the base pan - but they won't tell me how to rectify the problem - can u help!?
