Water fills the tub then nothing happens.

Be sure the drain line is above the TUB level!!

If your dishwasher is brand new, then call Bosch service as they can repair it under warranty.

Hi,
Its sounds like you have a siphon going on, this happens when the drain hose it too low during fill and as the water enters the unit it exits through the drain hose. To stop this the drain hose needs to be higher than the tub itself, meaning: raise the drain hose behind the washer to about control panel area. This will or should stop the siphon effect and allow the water to remain in the tub. If the drain hose is low this siphon will start again.
I hope this helps

What has happened is that your water pump has gone out and it cannot pump the water out of the washers tub. This is a common issue and replacing the pump is not that hard assuming you have the time, effort, tools and energy.

it could be the programer at fault or,,,there is a small pipe from the bottom of the tub that gos to a censor at the top of the washer its the over fill censor pull off the pipe from the censor at the top and blow down it if there is any yuck in it this should clear it out and it may then work ok

Check you drain line. It may be too low or the air gap is blocked at the drain pipe.
A test is remove the drain pipe from the wall drain. Hold it up high and turn the washer on to fill.
If it fills and stops, then starts agitation. Repair the drain hose.

gabehart....sounds like belt is slipping. Replace it. The water pump is on a separate smaller motor so is not affected by the agitator/spin motor.

It leaksYour washer can develop several types of leaks. You can track down a leak based on when it occurs: 

During fill only
During drain and spin only
All the time

During fill only
If the washer leaks only during the fill cycle, check these:

Air-gap device -The air gap is a small device found on most washers that prevents the wash water from being siphoned into the household water supply. It's located either mid-way along or at the end of the black rubber hose that comes from the water-inlet valve. Often it's made of translucent plastic. If one of the air-gap components deforms or cracks, you may need to replace it.


The tube -There's a rubber tube that runs between the water-inlet valve and either the air-gap or the inlet spout. If it cracks or breaks, it can cause a leak. 


Inlet spout -Most washers have a plastic spout near the top of the main clothes tub that directs the water into the tub. If the spout cracks or breaks free of its mounting, it can cause a leak. 



During drain and spin only
A washer that leaks only during the spin cycle often has a leak in the main drain hose. Inspect the entire hose and correct any problem you find. Alternatively, the steel or plastic outer tubs can rust, split, or be punctured. This may be most visible during large loads and high water levels. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details. 


All the time
If the washer leaks all the time, check these:

Hot and cold water fill hoses - Check the hot and cold water hoses from the household plumbing. If either hose is leaking, tighten it or replace it, as appropriate.


Main tub seal - The main tub seal is located between the transmission and the outer tub. It's the primary water seal in the outer tub for the transmission-shaft entry point. If this seal leaks, you can see the leak by opening up the machine's main access panel while the machine is full of water with a small amount of detergent in it. The leak appears at the underside of the outer tub, at or near the center. This seal is difficult to replace. You probably should call a qualified appliance repair technician. 


Pump - If the pump leaks, you can probably spot the leak when the tub is full of water. The pump has two or more black rubber or plastic hoses attached to it and usually has a drive belt that spins the pump. If the pump is leaking, you need to replace it. 


Outer tub - Over time, the steel or plastic outer tubs can rust, split, or be punctured. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details.

If the timer cycles your lid switch is ok.
most likely: motor Switch (on Motor), condenser next to motor, motor itself, or wiring going from the time to the switch,

It is probably cost efficient to replace the unit rather than trowing parts at it .
