We keep filling up the dishwasher and switching it on and it keeps coming up with a light showing check water. We have emptied it many times and checked that the water coming in is ok and it seems to be. We keep having to turn off the water in valve for 5 minutes and then switch it back on again and off we go. When it reaches the end of the cycle we still have water in the machine and the water is dirty in the bottom tray where the water outlet is.
There will be something jamming up the drain pump empty the water out of the appliance if you study your operating instructions there will be an intsruction in it as to how to remove the drain pump cover and clear the impellor be carefull ill bet is a piece of glass

To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button. To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show “88′ when REGULAR WASH button is pressed and “8h” when Delay Start button is pressed. To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4). 0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault 1 = Aqua Sensor (“Sensotronic”) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test) To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty. If water level switch (f1) has failed (opened), display will show fault code “4′ and unit will continually fill and drain where testing won’t be completed. If flow switch (e5) has failed (opened), display will show “0′, water won’t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code “8′ immediately and testing will end shortly after water has started circulating. --------- The dishwasher not draining is most probably faulty drain pump or drain hose is got bit loose.It has to be checked and confirmed .You can get required parts from www.repairclinic.com Thanks.

Your dishwasher is stuck in flood mode. Bosch dishwashers are built with flood switches located in the bottom base pan of the dishwasher. The flood switch is connected to a rod that activates a small interlock switch. When water enters the base pan on a Bosch dishwasher, a Styrofoam puck lifts the rod, activating the flood switch.
When the flood switch is activated, the dishwasher will go into a no-fill, only-drain mode. The drain motor may also run with the door open to the unit. This is definitely a sign there is water in the base pan. This can be caused by the drain being clogged. There are two ways to fix:
1. You can uninstall the dishwasher and tip it forward to about a 45 degree angle to drain the water out of the base pan. (This is probably why Ian Bint's solution fixed the problem.) Be sure to put a towel under the dishwasher first so that the water is soaked up in the towel instead of going all over the floor. Once you've drained all the water out of the base pan, reinstall the dishwasher and begin a cycle. If it fills and runs, you are good to go.
2. You can also unplug the unit, then remove the kick panel at the bottom in the front. (It's attached with two screws.) Then get some old washcloths or small towels and reach into the base pan below the dishwasher to soak up the water. The pan is directly behind the plastic base panel rim. Once the pan is empty and dry, your dishwasher will no longer be in "flood mode" and will run properly.
If the base pan keeps refilling with water and the no-fill problem returns, there is definitely another issue, such as a clogged drain. At this point, you need to decide whether to invest in an expert evaluation by a certified Bosch repairman and make the necessary repairs, or buy a new dishwasher.
On bosch dishwasher if the base senses a water leak the unit will not
fill & the drain pump will come on. I recommend checking for water
in the base & locating the source of the leak if you see water in
the base. Other possibilities; fill switch, water level switch or water
valve. There is no reset for this problem.
Bosch has a safety float switch under the dishwasher basin. If water leaks into this area, the float rises and turns on the drain pump to clear out the water in the dishwasher. Hope I explained that ok :) Anyways, usually a leak somewhere causes this and unless the leak is fixed and water is removed or evaporates, the dishwasher will remain in the drain cycle.
Is there no water coming in( hear no water at all) or no water NOT staying in ( drain motor running) ... the float switch is a safety to keep the dishwasher from flooding ...turns on the drain motor as soon as the door is closed..
I could check the control and see if you have power to the water valve.. maybe a control problem if no power..
is your appliance a miele? normally this is causeb by blockages ( bit of plastic or paper wrapping/ milk bottle tops etc) inside the impeller of the main circulating pump (motor) restricting the flow of water the only solution is to fisically remuve the obstraction by temporarelly remuving the motor and cleaning not a simple job
