    Ran a few packets of unsweeted lemonade through the dishwasher - the citric acid cleaned off the soap residue from the sensor telling that was keeping the machine in the drain cycle. I run this through the empty dishwasher every few months now and the dishwasher runs flawlesly. I also never fill the soap cup completely to prevent residue build up in the first place.

I had this same problem and in addition as it ran water dripped out the bottom while the dishwasher was running just before the tap light came out. Check the outlet hose is not blocked. Ours was blocked at the T junction where it met the sink outlet. Once the blockage was cleared we hit another problem - the pump kept trying to drain - even when the door was open. Found an excellent solution to that on this site. It had occured as the previous problem had casued the flood switch to be triggered. We had to tile the sihwasher back 45 degrees to fix it. Now its workig fine again.

SOURCE: Loud humming noise when dishwasher is filling up with water

your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.

there are two components that start before the circulation pump.(wash noise you hear)

first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.

the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..

How to run self test on bosche dishwasher


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!

No water is coming in and its almost like it is 3/4 of the way through the cycle and stuck in the same position.


If the wash motor continuous to run but the cycle is frozen then most likely the thermostat or heater is faulty. Try to run one of the short cycles like rinse only to confirm if the cycle is completed.

When I press the start button, Bosch dishwasher (model SHY56A 05UC) just keep running the motor pumping the water out of dishwasher, irrespective of: 1) the wash cycle it is on, 2) whether the door is...


what is happenig i believe and has happened to me 2 times is that the water level float that is on the left side of dishwasher is stuck.

Either remove side panel and flick lever or pull dishwasher out and tap lower portion of panel and this will cause the level to move and then see hat happens

Bosch dishwasher fills with water after cycle is completed


Sounds like you need a new water inlet valve. It's not shutting off completely, so water slowly enters the machine even while it isn't running.

Bosch dishwasher timer freezing


There is a recall on the control board of many of these models, butyour problem is likely not related. It sounds like a plugged drain system or a possible bad drain pump. That's why you are hearing the pump running constantly. I have written a guide to help. It is here. Thanks!

Running time of dishwasher


he cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing
Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water. 

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit. 

Cycle not completing See "The cycle doesn't complete" section. 

The cycle doesn't complete If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

  • On some units, the pause is timed and the unit continues after the allotted time.


  • On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.


Timer Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

Bosch SHU43C


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!

Runs all the time


I just had this problem. I found an article that explained it and had the exact picture of my problem. It is http://fixitnow.com/wp/2006/06/09/bosch-dishwasher-takes-forever-to-complete-a-cycle/ .
I am watching my the dishwasher just move into the rinse cycle as I type this. My guess is that I just saved either $400 for a repair or $1000 on a new dishwasher. I think it is time for me to make a donation to that article's author.
