Any suggestions would be greatly appreciated.
Well, the first suggestion would be to throw this piece of Italian junk on the nearest tip.
However, lights 1+2 suggest a drain time out error, you may have a pump or outlet hose blockage. The pumps are prone to blockage but usually easily cleared.
It may be nothing to do with the previous repair, the smallest thing will jam the pump, glass, bone, sweetcorn, etc, etc.
Was your previous repair done by Indesit or a local independent?
Either way I would call them back but expect to be charged as this could be due to something entirely unconnected with the original fault.
That which can be asserted without evidence, can be dismissed without evidence.
