Dishwasher motor runs (even with door open), but no Water
Our Bosch SHX46A05UC dishwasher is not spraying water, when turned on. Additionally, the motor runs even with the door open, and when closed, no water, although the motor runs. We've had this in past, and eventually it works again, but after a few weeks, it occurs. Could it be a drain problem? or a sensor issue?
Re: Dishwasher motor runs (even with door open), but no...
I am currently having the same problem with the same model. I have removed the left side panel and suctioned out the water that has collected in the overflow pan. That was tripping the float in the pan. I am now running a cycle and it seems to be working properly, but I am concerned that I am missing the leak that caused the overflow pan to fill in the first place. Any suggestions?
Re: Dishwasher motor runs (even with door open), but no...
I'm sure you've found a solution by now, but figured I'd post my answer for anyone else experiencing the same issue. I just had the same thing happen to my brand new Bosch (no water, motor starting when door is open). The service man told me this is a sign that there is flooding. He removed the toe-kick plate and sure enough saw water in the pan/tray that is there (whatever it's called). He removed the unit and found the drainage hose had come loose and the floor was all wet. He told me the motor starting with the door open is a deliberate feature to alert you to flooding! I had no idea! Unfortunately the Bosch customer-service agent I spoke too had no idea either. I dried up the floor. He reconnected the hose (with clamp tie) and problem solved. Good luck to anyone who experiences similar. I hope this helps!

Re: Dishwasher motor runs (even with door open), but no...
I believe the problem is in the electronic board. It is getting a different signal thus not allowing it to run properly. You can have a local service technician for the company look at it but this is probably the cause.

the unit will try to complete the last command it was engage in before it went in the overfill safety mode. you must perform a cancel drain cycle to reset unit to default setting. Remember the drain cycle is 2 min and must be completed to reset main control. however if it went into a overfill status you have a leak and it generally comes from the pressure chamber on the lefthand side of unit where the water enters tub
I can't see how any installation problem would cause this - if the dishes are still wet at the end of the cycle, you'll probably find the water isn't heating during the wash cycle. The dishwasher uses steam to heat the washing compartment and dry the dishes. It would appear that the dishwasher isn't heating water internally.
Even if the washer was accidentally connected to the cold water supply ** (see note), this shouldn't happen as regardless of the water supply temperature, the washer should still heat the water to the correct temperature internally.
** UK dishwashers should be connected to the cold water supply. For US installations, dishwashers are commonly connected to the hot water supply. For other locations, please consult your installation instructions.
I suggest you start a regular wash cycle and leave it to run for 10-15 minutes. Then open the door and test the temperature of the water in the base of the washer by hand. The water should be hot and there should be steam present in the washer when you open the door.
If the water is cold or only warm, the water isn't being heated internally or isn't heating to the correct temperature, in which case you should contact the retailer or Bosch Service immediately for a replacement. Do not accept an offer of repair on a brand new washer!
Additionally, do not attempt to repair the dishwasher yourself when under warrantly as this will invalidate the warranty.
Hope this helps. If you need further assistance, please let me know your location and the model number of the washer. This should be laser-etched into the top of the door if you can't find it on any of your paperwork.
Are you please able to confirm what exactly is happening when you mention "dishwasher just keeps going".
Is it in a wash cycle and throwing the water around through the wash arms or do you just hear a pump running with water sitting in the base. Most likely there is a leak into the base and the auto stop circuit is trying to empty the dishwasher by running the drain pump. I would suggest you check the base of dishwasher for leaks.
The pump attached to the end of the motor shaft inside the tub may have broken. If it doesn't spin the water wont pump out but usually the water wont spray on the dishes either. Watch it run a second with the door open and the door switch make to see if it's spraying.
Sounds like your recirculating pump is clogged If it is water can't get up enough pressure to turn the sprayers. You'll need to start pulling parts out of the bottom inside to get to that pump. I don't work on a lot of Bosch, but that sure sounds like it to me. I see this a lot. Hope this helps...
I have a Bosch that was stuck in pump down mode even when the door was open. The problem ended up being too much water in the drip pan below the unit. There is a float in the drip pan that actuates the same limit switch as the internal overfilled float. I had recently cleaned the incoming water filter and must have loosened the water line tube.
If the water is not draining from your dishwasher, verify the following:
Verify that there is not a clog in the drain hose or air gap. This is typically the reason that a dishwasher won't drain and the clog is usually where the drain hose attaches to the garbage disposal or sink drain pipe. Remove the hose and clear any clogs, then reinstall.
Verify that water from the sink drain is not making it's way into the dishwasher. I would recommend creating a high loop in the dishwasher drain pipe, which is attached to the sink drain, under the sink. The high loop can be fastened to underneath the countertop. This will prevent any water from entering the dishwasher from the sink; it also prevents the dishwasher drain water from making it's way back into the dishwasher
Verify that the pumps drain impeller is working. You can reach the impeller from inside the dishwasher after removing the lower rack, spray arm, and arm support. This typically involves removing a few screws. Once upper parts are removed, inspect the drain impeller, which pushes the water toward the drain port, for any cracks or missing blades. If the impeller is defective, the water will not drain properly and you would need to replace it.
Verify that the drain valve is working; many are controlled with an electric solenoid that opens the valve, sending the water to the drain. There is a chance that the solenoid or the diverting lever could be stuck which would prevent the water to drain. If so, try to free up the solenoid and lubricate the lever. Otherwise the solenoid or pump assembly may have to be replaced.
Verify that the motor is turning/ working and verify that there is power to the motor. If the motor hums but doesn't turn, it may need to be replaced. Motors can get stuck if not used regularly. If the motor is defective, the water will not drain and you would need to replace it.
There are ways to test the pump and motor with a multimeter. If you are not comfortable with doing this, you may want to have a technician test it for you.
The problem is hard water. There is a new product out called the dishwasher filtration system.It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee.You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks).

Main tub seal Door gasket or seal Water-inlet valve Hoses Main tub seal
Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.
The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:
Spray arm support
Then pry the seal out of its housing and replace it.
Door gasket or seal
Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak.
The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.
The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.
Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.
This is a little late for the OP. But, I had the same problem over Thanksgiving of 2008. I searched online and saw that other people had the same problem, but there were no solutions posted. So, I paid $130 for a service tech to come fix the problem - maybe this will save you some time and money.
The solution was simple...pour boiling water (I boiled about a half gallon of water in a cooking pot) straight into the pump where the water sprays out of. You don't have to pull your dishwasher out and no tools are needed. Just open the door, pull out the lower roller tray, remove the bottom spray fin (just pull straight up), and pour the boiling water straight into the hole where the bottom spray fin was attached to. Next, put everything back in place, push the Power switch on, select a wash mode, and close the door. The dishwasher should start spraying water inside as usual.
The service tech told me that there are only two pumps in this dishwasher...one to pump the water in (the one that had the problem) and one to pump the water out. When you don't use the dishwasher frequently, the seal in the wash pump seizes up (sticks together). You can hear the motor humming, but the pump isn't able to send the water up into the spray fins. By pouring boiling water into the pump, it helps to break that stickiness and allows the pump to start sending water up into the spray fins. The solution is to run your dishwasher at least once a week. Even if you don't have much to wash, run a rinse cycle to let all the parts move and stay loose.
One other tip the tech told me is to pour a cup of white vinegar into the pump when you go away on vacation and the dishwasher won't be used for a week or more. This should keep the seals from sticking together. I haven't tried this yet.
