Bosch dishwasher fills with water after cycle is completed

There is an anti flood valve on the bottom of the unit. IT could be sticking or have a bad connection. IT should look like a dome shaped housing on the bottom of the tub. If that is not the problem then you are looking at further troubleshooting to see if it is the contoller.

this sounds like flow sensor failure,it it fails machine will either not fill up or fill and drain without washing its a cheap part to replace and is fitted downstream of inlet valve behind l/h/s side panel either attached to inle hose or heat exchanger.

Here is an excerpt from "Bosch Dishwasher Troublesoooting".

Running a Test Cycle
Bosch dishwashers have a test cycle which can be run as a troubleshooting measure. The method to run this test cycle is similar across the Bosch dishwasher range so if your dishwasher features seems different from those described below then try experimenting, as the process is fairly straight forward and will be very similar. Bosch dishwasher model numbers are usually found around the top or lip of the door. One of the most common differences between dishwasher models is simply the names of the buttons. For example in the first example below, POWER SCRUB PLUS and REGULAR WASH may be called WASH and ECO depending on your dishwasher model and the country you are in. The other key difference is whether your dishwasher has a display panel (which can display error codes) or not (in which case a program light will illuminate to tell you the fault.
To run the test cycle hold down the POWER SCRUB PLUS and REGULAR WASH buttons. Whilst held down press the ON/OFF button. The lights above them should flash. Now you can check the status of each dishwasher program by pressing its button. Now you can run the full test cycle = Press the POWER SCRUB PLUS and REGULAR WASH buttons again. The dishwasher will start up and when the cycle has ended one, if you have no display panel on your dishwasher model the indicator lights will illuminate if a malfunction was detected as follows -
CLEAN - A temperature sensor fault. If this is the case then the test cycle will be very short as the dishwasher will terminate the test once it's been detected.
RINSE/DRY - A water sensor/filling fault. If this is the problem then the test cycle will not complete as the dishwasher cannot detect the right level of water, the dishwasher will just keep filling and draining again.
WASH - A heating fault. Check your heating element.
If you do have a display panel on your Bosch dishwasher then after the cycle is complete an error code will be shown if a fault has been detected. The error codes are as follows -
0 - No errors have been detected.
1 - A water sensor/filling fault.
2 - A heating fault.
4 - A water filling fault. This can also appear as F on the display during a normal cycle.
8 - A temperature sensor fault.
When troubleshooting your Bosch dishwasher, running the above test cycle is a good start in diagnosing the problem and should give you an idea of where the problem lies with your Bosch dishwasher and what fixes and repair are in order. Our general troubleshooting page will give you some ideas on other things to check on your dishwasher. Good luck!

Here is what I found that makes my bosch dishwasher come on. It has the same problems as the OP. I pick the cycle I want press start. The DW will sound like it's trying to drain. I let it run that cycle which takes about 30 seconds. It then starts another cycle that sounds different from the first and when it stops I turn the DW off and then back on, it resets and then it starts the wash cycle. I've done this twice and it has worked both times. I do not know what is causing this but it's better then what I had to do to get it to reset.

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

Test the water inlet electro valves.

Hi there,

Unfortunately, it seems that the heating element has failed. The dishwasher uses steam to heat the tub to dry the dishes. I suspect your dishes are also being washed in cold water.

To check this, please run a regular full wash cycle. Allow the washer to fill with water and run for about 10 minutes, then open the door and feel the water temperature in the bottom of the washer. If the water is cold, it's more than likely the heating element has failed.

There are other possible faults which would cause the element not to heat, but these often prevent the dishwasher from completing the cycle. If the water is cold but the dishwasher still drains the water at the end - and completes the cycle - the heating element has probably failed.

Please try this simple test for water temperature and let me know if you need further assistance.

Regards,
BElectric

Replace the water fill valve, it's leaking.

I had the same problem with no water coming in. Each model may be different, but i solved the problem by holding down the clean drain button for 5 seconds. On my model, it is two buttons simultaneously, then closed the door and waited for the washer to cycle through. Once completed, turn off and then back on again to run normal load. If this does not help. Call Bosch Directly. They have an excellent customer service desk (1-800-944-2904) or http://www.boschappliances.com/kitchen-appliances-dishwashers_dishwashers_Integra_800-series.html.

Hope this helps

it sounds as though the circulating pump may not be operating. if so fault is often due to the pump capacitor being faulty and this is a cheap part.
