BOSCH DISHWASHER QUIT MID CYCLE NO LIGHTS ON DISPLAY AND ACTS LIKE NO POWER. POWER INCOMING IS GOOD AND POWER TO SWITCH IS GOOD. TRIED NEW SWITCH WITH NO LUCK. MOTOR WILL RUN IF OVERFLOW FLOAT UNDER DISHWASHER IS LIFTED.

The specific steps to reset a Bosch Series 3 dishwasher can vary depending on the model, but here is a general method that may work:

1. Turn off the dishwasher by pressing the Power button or unplugging it from the power source.
2. Wait for at least 30 seconds to allow the dishwasher to fully power down.
3. Press and hold the Start button for about 5 seconds.
4. While still holding the Start button, turn the dishwasher back on.
5. Release the Start button when you see the display or indicator lights change, which may take a few seconds.
6. Press the Start button again to initiate a new cycle, and the dishwasher should now be reset.

If this method does not work for your specific Bosch Series 3 dishwasher model, you can try consulting the dishwasher's user manual for specific reset instruction

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!

Have you tried to turn the mains power switch off and on to see if it resets the drawer to off state. Need a bit more detail of what you see on the display etc. when you try to turn back on.

Check the wiring in the units junction box. Its located at the bottom right corner. You will likely find melted connectors. If so, you need to cut the wires back and replace these connectors. Make sure you turn the power off before doing any of this work of course. Good Luck.

When the power button was pressed, did the circulation motor grunt? Check connection to display module. Might be missing neutral.

press drain and cancell button at the same time
