We have a Bosch S2R7B counter-top dishwasher which appears to be completing the wash cycle, starting at 5, but the dishes are still dirty and the tablet has not been used. The water supply is on and going into the machine but on test (empty) appears to only let a small amount of water in then the water stops running. Have checked all the filters that I can get at but it still will not run properly. Can anyone help?
