The 'check water supply' light is illuminated on my Bosch dishwasher SGS53C12GB. I've removed the top, sides and kick board. I've checked the inlet water supply pipe filter and cleaned it. I've removed the inlet water supply pipe and flushed water through it. I've tipped the machine on its left side, back and partially upside down. When the reset program is selected the light goes out. When you then select the rinse program the machine runs for about 30 seconds then the light illuminates again.

Sorry to just add to this, rather than solve it, but I've had the identical problem this morning! Oh, and to make matters worse, mine's a built-in dishwasher and it seems to have been fitted with special tools (i.e. not using screws, but rather fittings with a proprietary sort of head on them) so I can't even remove it to get at the water inlet! I hope someone out there will take pity on us ...

I've just had the same problem. The wash cycle had about 30 minutes left to run and the machine just stalled with the little red tap showing on the display. I scooped as much of the water out of the mahine as I could and cleaned all the filters, checked the pump impeller and ut it back togther. Ran a rinse cycle, then a full wash cycle with cleaner to see if that helps. It has, but not suer if it's a premanent fix. Off that the water suply light should come on when there's nothing wrong with the supply and the machine was full of water
