Hi All

This dishwasher currently has me stumped.
The origanol customer complaint was a failure to drain and that he had checked for blockages and wanted a new drain pump fitted which I have done but the fault still persists.
The machine comes up with the “Check water” light, I have had all the drainage hoses out of the machine and can confirm that there is no blockage in the machine, I have even checked the anti backfill valve. I have now watched the machine through 2 quick washes and observed it fail twice, the first time it had just finished the main wash, drained and was refilling for the first rinse when it stopped abruptly, the second time it went all the way through the cycle and about 5 seconds after it finished draining the water from the last rinse it came up with the error light.
As far as I can tell the flowmeter is working perfectly and so are all the valves and the drainage system so I am not sure what it is moaning about.

is the water light steady or flashing ?

does sound like a drain or fill fault. Manual also mentions blocked filters but assume you have looked there. Is water pressure ok ?

As you realise Jem. Bosch manuals are like hens teeth

not sure what you know about virtual sensors but if your not sure try

test routine may work but its the closest we can get to the later machines
