Bosch lifestyle dishwasher not filling with water. I undid the bottom and it blew out an air block and started. When reconnected again it is doing the same thing

Hi, if its still under warranty you should call bosch and get them to arrange a service engineer to come out and check it for a fault.

The machine is telling you to check the water supply which fills your dishwasher. Check if the water pipe is frozen or blocked, do you need to turn on a tap to allow the water go flow to the dishwasher ? :)

On my hoover 200m (top loader) I had a similar problem. I turned off the machine & unplugged it. Closed water taps both hot & cold. Manually emptied machine with large cup. Undid bottom outlet hose by unclipping.The residual water will come out! I undid the 3 screws on the control panel. Tilted the control panel forward. The water level is manual control using a diagaphram pressure control to set water level. This had a hose. I disconnected both ends and used a bicycle pump to blow air thorough it. Underneath I disconnected where the hose goes into machine (clips) and also blew air from the top to check it was clear. After reconnecting everything the machine now does not stop filling and does not overflow anymore. Hope this helps.

the drain is blocked somewhere. It is probably trying to drain water out but is not successful and then shuts down.

The water level detector pipe could be obstructed / blocked. This thin plastic pipe is at the bottom of the washer and as it fills to the correct level of water the pressure in the pipe activates a water level switch in the washer. Sometimes the air pressure pipe becomes blocked / obstructed or the contacts of the pressure switch become burnt. You can disconnect the pipe and blow through it and the pressure switch is normally factory set and does not need adjusting. Replace it if necessary.

make sure the supply tap is turned on

most bosch have the inlet valve at the end of the fill pipe and it has an anti-flood device.
try turning off the water, take off the fill pipe then reconnect it and see if this works.
taking off the fill pipe resets the anti-flood device

i know this sounds daft but --
turn off water. disconnect fill hose from water supply. wait 5 seconds and reconnect fill hose then try it out

I have a Bosch Classixx with what sounds the same problem.It would not drain properly and hummed even when the front door was opened.After a couple of days it ponged a bit.This is what I did.Sypnoned off yukky water with a short length of hose (fill pipe with water from tap don't **** on it!!).Cleaned filter under cutlery tray at bottom.Then put a TEASPOON of bleach if on main drainage or dishwasher cleaner if septic tank.Ran on a hot wash and see if it sorted problem-it didn't but did clean system.
Syphoned off again -take care.Isolated electric and water supply.-Should do that first perhaps Pulled out from under counter undid drain hose at sink end and water at machine end.I then put machine on side and undid bottom silver plate.Note position of polystyrene float switch cover.I then followed drain hose to drain pump and undid it by twisting it like a bayonet light bulb undoing clip levering with screwdriver (not for feint hearted as easy to break) -I then checked little impeller for foreign object-found none so pulled off pump housing by rubber hose to bigger pump thing next to it and found small bit of plastic put it back together and hey presto problem sorted-I was told it might take two hours for the expert to do it once on his workhop bench-it took me about 30 mins plus a bit of head scratching and a yank and push or two which could have been rather expensive -I was lucky!
