OK Bosch Dw fans.........here is the fix if your SHX dishwasher is stuck on the drain cycle. This may save you a couple hundred bucks.......so listen up. There is a tendency for the very small float switch to STICK in the ON position, which will cause the drain motor to continuously run......and DISallow any other function to work. DISCONNECT POWER. Did I mention to disconnect power? Take off the front base cover....2 torx screws. Remove the other 2 torx screws in the metal clips that fasten the top of the DW to the underside of your countertop. NOW...carefull slide your DW out. You may have to disconnect your water and elec supply if you do not have enough slack to pull it out. Once the DW is out of the cabinet, remove the shiny metal cover on the LEFT side by removing a single torx screw. You will now see a small plastic assembly with a red plastic piece that moves up and down as it rides on a small red styrofoam float. This up and down movement engages a small white plastic switch visible with 3 wires coming out of it. You can carefully UNSNAP this switch out of its mount, and pull the 3 wire plug off of it. THere is a small square blue plastic tab that is supposed to easily slide in and out of the switch. If it is stuck IN, you can sometimes tap the switch and the blue tab will pop out, which is what it is supposed to do without tapping it. You can carefully with a knife blade separate the case on this switch and note the way it comes apart. Clean out any micro debris out of the small channels that the blue tab ride up and down in. Then set it in the channel while holding up the small switch tab that rides on it and see if it slides up and down without sticking! I like to take a piece of wax paper and rub in on the channel and blue tap to provide some lube for the switch to slide easily on. Now, put the switch back on and manually move the red plastic assembly up and down while you are watching the blue tab. The tab should ride up and down with the red assy. If not, buy a new switch. Google the # on the switch and order one. If the tab slides up and down, put things together in reverse order and give it a try. Hope it works for you. This should take you an hour give or take. Take the $200 you just saved and have a night out on me. ........so even though these German Appliances have a good name because of past reliability, the american tendency to value engineer them with plastic parts to reduce costs and increase profit.........just cost you an hour of your time. Will we ever learn.? ......if it ain't broke, value engineer it until it only lasts through the warranty period so you can then collect service and parts blood money from your fellow american.

SOURCE: Dishwasher not draining water
I had the same problem....removed hoses, checked for cloggs the hole nine yards.....Inside of the unit towards the back in the bottom is a filter cover and in the middle is a valve that you just screw out. It has a rubber stopper that overtime breaks down....I was able to pick up the part locally for about $17CDN, replaced the part and the unit drains properly now.....now I have an issue with no power

Hi and welcome to FixYa, I am Kelly.
There is and internal float switch that controls power to the inlet water valve. If the float is sensing that the unit is full of water it will go through all portions of the cycle but.... will not have any water in it at all.
Take a look at this diagram and check items 302 through 308:
The float should move up and down around 1/2 inch. I believe your float is stuck in the UP position. This is usually caused by food particulate on the stem (Item 306). Clean it up and it should work. You can gently push the stem up and down from under the unit and you should hear the micro-switch click as you raise and lower the stem. No click = bad micro-switch / no power to the inlet water valve. You can briefly jumper across the micro-switch to see if you get water flow during fill cycle. Just be aware of the dangers of working on live circuits.
Thanks for choosing FixYa,

It is possible that the
machine does not start off the cycle because there are errors or feedback from
the inputs. For the program to start up the main program controller must
initiate the INLET/PUMP MOTOR/DRAIN to work
when it is commanded .If this does not happen then the voltage at these
points must be checked or the fault
relates to no voltage/drive from the controller. This means the controller is a

water flows then the flow should be good, if not the inlet valve is bad or there
is dirt in the filter. Also check the flow at the inlet of the water line. What
is most important for the motor to start functioning is that the door switch
must be ON when the door is shut or this will be an error for starting the
motor. The water pressure must be good and the spraying must be seen to be
good. If there is low pumping or pressure then the spray arms will not turn
around to inject with pressure. If so
the pump must be checked for clogging.
check this link:
after the wash the drain valve will be activated, the water is allowed to come
in to rinse and then finally the drain valve/pump activated so as to drain off
all the water.
that a fault in any of the cycle will relate to the specified action, so check
the command from the program module and then the executing device be it the
valve or motor or pump.

Please recheck the machine with the tips given here as I think the main program controller is activating the drain to work. So for the program to start up the main program controller must initiate the INLET valve to open up and allow water to flow into. If this does not happen then the voltage at the inlet valve must be checked or the fault relates to no voltage from the controller but if this activates the drain pump then it means the controller is a suspect.
If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor .
Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water .
Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.
