My dishwasher is doing the same, overflowed mid cycle, I emptied it and now first 3 lights flash and it gives warning beep, pump runs to empty constantly, think there is leak filling bottom tray which is giving micro switch wrong information that machine is still full, some people have had salt partition leak and others feed pipes to water spray headers, sugest u strip and check for leaks. Havent done mine yet so if you get it fixed please reply.
