A malfunction has occurred. You won’t be able to fix this problem.

    I assume that but what part malfunction. I am leaning towards either a stuck float valve or a failed limit switch.

    Control board. Doesn’t it give a error code?

    A failed limit switch inside the door would make sense because it still runs with the door open but that wouldn’t cause it to keep draining. When water is detected in the base of the dishwasher, the drain motor will stay running even with the door open. The float switch is responsible for detecting water. To reset the float switch, dry the area underneath your dishwasher.

Bosch dishwasher shy56a05uc 14

I would assume it would leave water in the machine. some machines have this as a function. it is used to keep water in the drum to stop items becoming excessively creased. it is mainly used if you are not going to empty the machine for a while. you should be able to press the cancel button again to start the draining process.

Bosch dishwasher model SHY56A05UC/14 door wont latch. It will run but of course water comes out as it is not locked.

That sounds more like a gasket problem then a lock problem. Check the rubber seal on the door for damage. Even a small imperfection in the seal can cause the door to leak even though the lock is engaged.

Or is it that the door just won't close at all? If that's the case, check the locking mechanism to see if there's anything jammed in there. If so, remove it and that may fix the problem.

Bosch dishwasher model shy56a05uc/14 door wont latch

I tried the various solutions on this site with no success. Finally I wedged it shut with a nice clear plastic door stop. Worked perfect (who cares if people think it looks funny, I am not hand washing and still am not out any extra dollars)

I have a Bosch SHU9955US/14 (Integra) dishwasher. There is currently a 0 with and asterisk showing on the display and the unit will not run.

see this causes and fix it. God bless you
Thermal Fuse If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work.

Door Switch The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.

Main Control Board The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. YOU should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

Touchpad and Control Panel If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced. On some models the touchpad and control panel are sold together and will need to be replaced at the same time.

Touchpad If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced.

Timer The timer allows power to flow to the proper parts at the proper times. If the dishwasher won't start, the timer might be defective. Keep in mind that timers are often misdiagnosed as the cause of a problem. Check other components first before replacing the timer.

My Bosch SHV46C dishwasher keeps running, even when the door is open, unless you turn the control switch off. Then, when you turn the switch on, it starts running again.

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.

My SHY56A05UC Basch dishwasher runs and dose not shut off

The dishwasher is stuck in drain mode because there is water in a catch leak area underneath, it may have been caused by soap suds over flow or disposal backup. Remove bottom kick plate and vacuum out any water, then run dishwasher again and look for water leaks.

Bosch SHX46A (6 years old) Selected regular cycle, pressed On and closed door. Cycle did not start normally. Pump runs, but no water is coming into the DW. I confirmed the water supply line is turned on....

From your description, I doubt that the problem is door latch is the cause.
The first thing that a modern dishwasher does before it begins to fill with water is run the drain pump.  It appears that this DW is not progressing to the next cycle (inlet water) and because the pump runs even when the door is open, I agree that the controller card may have failed.
If possible, inspect all the wire connections (remove main power before you do this) ... if there is a loose connection, the controller could do odd things.
Good Luck!  Please report back what you find, OK?

Have a Bosch shy56a05uc dishwasher that suddenly stopped working to a point. I believe it is related to the door latch switch, because I don't feel the door securely latch shut when I close it, and I also...

Does your dishwasher electronic control or mechanical timer? if mechanical timer, I encounter a similar problem n change the mechanical timer. that problem solved.

Bosch SHY56A05UC/14

There is a pass through the lower back side of the dishwasher that also has a restraining device to prevent drain hose from being pulled off of drain pump. After passing hose through this opening, connect hose to drain pump. Note: there is another restraining device built into lower plastic housing which has a finger notch to accept hose and keeps the drain hose engaged in to drain pump by not allowing hose to back out of drain pump/ hose interface.
