Bosch Dishwasher

what is your model number? list it so I can look it up, also check to see if there is any water standing in the bottom pan,not inside where dishes go, down behind where toe plate is.Remove toe kick plate,remove panel behind kick plate.If there is water inside lower pan there is a float switch that will trip when water is present.only the drain pump will work and no water will come in unit.If there is water in lower pan you have 1 of 2 problems,1 you have a leak 2 the unit is oversudsing... to much soap. Dry up water in lower pan and styrofoam float switch will reset run unit check for leaks, put 2 tbls of cooking oil inside dishwasher to get ride of oversuding issue

Turn the water of at the inlet, diconnect hose and then reconnect it, it could be an airlock
