Have a Bosch SHX46B02UC. Dishwasher would not work. Found water at bottom of unit and would only here a pump. The pump would stay on overnight if left on. I sponged out the water at the bottom of the unit and the unit would start. I can't seem to see where the water is coming from. Removed the inlet valve and this did not seem to be leaking. There is a leak below the tank (where the dishes go). Any suggestions?

SOURCE: Leaking water on floor during drain cycle

First the source of the leak needs to be identified. pull the machine out from under the counter and remove the left side panel exposing the blue float assembly. Turn the machine on and observe the fill cycle. if water comes out anywhere on the fill mechanism then the inlet valve needs to be replaced. once the machine has filled and begun to cycle cancel the program and drain the unit. observe closly where the leak is happening. a leak during drain usually indicated a leaking drain hose.

Okay handy Mike,

First of all, is this a new dishwasher? Or, is it a used one? The reason I ask is because there should be a warranty with a new appliance and you should not have to worry, or have to pay for, any repairs.

The problem you are experiencing could very well be a water inlet valve problem (good assessment), but may also be something more simple. The dishwasher has a float inside the tub that is supposed to shut the water off, when it reaches the appropriate fill level. Check the float to make sure it moves up and down and that you can hear the switch "clicking". Sometimes small items get stuck under the float and will keep in the up (or shut off position).

For some helpful part locator drawings refer to searspartsdirect.com and type in your model number. An illustration of the water inlet valve can be found under the "Frame" heading in the next page as item number 24 (part number 154195301). The float and float switch can be found under the "Tub" heading as items number 13 (part number 154144301) and 24 (part number 5300809863), respectively.

If you require further assistance, please let me know. I hope its something simple and you don't require parts. But, if you do, you know where you can get them. If you do not wish to order on line, use the part numbers provided and go to your nearest appliance parts retailer. I hope this helps you. Good Luck.

open machine when running and check both spray arms rotating - you will get a bit of water out. if spray arms not rotating, usual cause is debris in the arms. the spray arms only rotate by water jetting from angled jets at the end of the arms. take them out and make sure all debris removed

HI
Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person. 

SOURCE: Bosch SHU9925UC Dishwasher Stuck in Initial Drain Cycle

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.
