dishwasher
I live in the UK and have a 3 year old built-in Bosch dishwasher, model number smv50c00gb/14. It finished a cycle ok but then started beeping and flashing the "check water" red light. The only way to stop this is to power off at the mains. When I turn the power back on, after a few seconds the light starts flashing. The beeping also resumes and the dishwasher makes a rumbling sound.
I've tried tipping the dishwasher but that didn't help. I've also tried cleaning the filter om the input pipe.
You've got some large particles in there & it seems that you're running out of time before a complete draining. You likely have a partially blocked drain line from the sink side of things. Make sure your drain hose is clear to the sink drain or disposer & that your sink-top Air Gap (if you have one) is clean.
Your drain hose should enter the sink cabinet at the very top & your hose should be angled up from the sink drain or disposer inlet with no sag or dip below the top of that inlet to avoid any future clogs. You should be good to go after that's all squared away.
It was the fill solenoid, Bosch part #00622058. My kids and I ran a bucket test, operating the valve into a bucket and timing flow over one minute:
Don't do this at home (ahem), note the bare wires from the scavenged extension cord: it's a 120V solenoid.
Test runs produced 5,8 and then 6 cups of water in one minute with the filter completely removed. This explains the inconsistent behavior. The new solenoid from the local parts store produced 12 cups in the same condition.
The hose was grotty also, and is going back to FluidMaster under Warranty:

In the end, the solution was to tip the dishwasher backwards but at a far greater angle - about 60 degrees. This lead to a small amount of water running onto the floor and the problem was fixed.
