Bosh shu43c never stops running.

HI JAMES.ummmm new bosh...should work.if not and motor running cont.then it sound to me like is out of refrigerant or motor faulty.check condenser unit.should hot.if cold call under warranty or replacement i would say.good luck Ali

There is likely a thermal switch on this saw which will reduce power or stop power all together to the machine. This keeps components from overheating and melting, like your capacitor. Let it cool off and try again. 2 1/2 hours is a long time for a machine to run on a job.

SETTING THE MACHINE TO TURN ON
1. Make sure the dehumidifier is plugged in but turned off.
2. Press the button with the clock symbol below it.
3. Press the up arrow to set how many hours until you want the machine to turn ON. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours.
4. After you have stopped pressing the arrow buttons the display will return to the original display showing temperature and relative humidity.
5. After the above steps are completed the dehumidifier will turn ON in the number of hours that you have set (programmed).

SETTING THE MACHINE TO TURN OFF
1. Make sure the dehumidifier is plugged in and running. You should hear the fan blowing for sure.
2. Press the button with the clock symbol below it.
3. Press the up arrow to set how many hours until you want the machine to turn OFF. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours.

Before we jump to conclusions, you can try to clear element that discharges the water. The wholes in these units can become clog do to the detergent as well as food. Most Bosch units allow you to unscrew these pretty easily. Blow through them, or use a plastic tooth pick to clear any obstructions or both. Before you reattach, turn on dishwasher and listen to hear how much water is shooting out at the discharge points. Most Bosch have two discharge points one for the top and of course one for the bottom. Reattach units and Run dishwasher.

Should this fail it could very well be the circulating pump.

It may be more cost affective to just replace this unit. the circulation motors that are used in these dishwashers are not reliable. the wash impellers seems to have issues dealing with staying attached to the drive stud and shaft. this will cause the impeller ti shift inside the housing, causing noise and jams.

A new circulating impeller kit will cost about 100 dollars and, labor for this type of repair is 80 dollars an hour.

I have the same dishwasher and started experiencing the same problem last week. It is now fixed (at least for the moment). Here's what I did first. I checked the drain pan under the machine for water(none), the heater for continuity(okay), the float for binding(none), and the float switch for proper functioning(okay). I tried turning the ckt breaker off for a couple of hours to see if that would reset the control module(no effect). I then dissasembled the front door and removed the control module. I had previously read about the common problem of a cold solder joint on the heater relay pin on the control board. My heater was working and the joint looked good but I resoldered it anyway. I reassembled everything and it worked perfectly! My conclusion is that it was either a cold solder joint that was somehow causing the problem or a connector issue that got resolved during my disassembly/reassembly. Hope this helps.

My Bosch SHU43C had the same exact problem. I found the below solution on this site. Perhaps you already seen it.

My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!

I think if u take the left side pannel off u will find the meatering tank clogged up which can not fill up the machine at diffrent levels.

Make sure you have water coming to the dishwasher. Next check your dishwasher float. Make sure it is not sticking. If not you could have a problem with your fill valve. Check for voltage at the fill valve if you have 120V then you need a valve the solenoid is defective. Replace it.
