Bosch Running a LONG LONG Time and Watering Remaining

My Bosch SHU4302UC/06 is running for a LONG LONG Time...These problems seemed to have started after a house drainage problem occurred. Debris from the drainage problem could have backup into the dishwasher. The cycle takes 1.5 hours and water is left in the bottom.

There seems to be TONS more water that used during the wash cycle as well. Any ideas?

    I ran the hose to the sink. The drainage is definitely an issue. BUT their is still some water left in the bottom of the unit when the cycle is complete. Any ideas?

    our dishwasher takes forever! The counter on the front starts at 99 and counts down, but takes over 3 hours to do so. 

    Our old dishwasher took less than an hour! what can I do?

You could try running the machine with the drain hose leading to a large bucket. If it works OK in this situation then the blockage will be most likely where the drain hose joins the house drainage system - often at a junction under the kitchen sink. With the drain hose disconnected you should be able to see the blockage and clear it with a suitable pointy tool.
Let me know if this sorts it. Thanks, D.

    Hi again,

    I'm thinking there could be some debris in the hose itself, near to the machine or even partly clogging the pump. You might be able to clear it by running a cycle with no dishes but plenty detergent (or proprietory dishwasher cleaner) and when it starts to pump out get the drain hose really low to the ground into a bowl so there is minimal resistance to the water flow. Failing that you might need to turn the machine over and remove the hoses near the pump to get any heavy grit out of them.

    Hope this helps you a bit more. D

Bosch SHU4302UC/UO6 runs three hours.

Maybe wash temperature. The machine may be trying to heat the wash water to a preset temp and it is taking an extended time to get there. Maybe a faulty temperature probe or a bad element?
I know you will ask how this is possible when you have a final temp of 120 but that sound like a drying cycle temperature to me; not a wash temp.
I would leave the thermometer in through the cycle and you will probably find it will slowly get hotter in wash cycle and finally switch after a certain temp has been obtained.

I have a Bosch dishwasher Model number SHU4302UC. The dishwasher takes about four hours to wash dishes. During the rinse cyle it can be running for over an hour and I will open it to look in side and find...

possibilities are that of an inefficient heating element ie..scaled up if hard water area especially. whilst the cycle is being completed then the components are working... so other than the element check the drainage for blockages (slow draining adds time) & also water pressure as low pressure adds time to the filling..

Bosch built in dishwasher shu4302uc The dishwasher appears to run through the cycle but the cycle takes over three hours. When the cycle finally finishes the dishes are not completely dry. Is there a way...

There are no adjustments for cycle timing. What does affect timing is temperature of the water coming into the DW. The hotter your supply water, the shorter the time to cycle, BUT if your water is too hot, the cycle time may become too short to light the NSF 'Sanitize' indicator. But since the cycle is taking so long, this is an indication that the DW's water heater is not heating the water hot enough to advance the countdown timer in a timely manner. The control logic is waiting for the temp to come up to an appropriate level to ensure adequate washing, rinsing or drying times. Likely your display is showing '1' for a long time as a symptom of this problem, as well.  - This link has procedures to run self-tests on various Bosch models. I suspect that you can confirm a 'heater fault' on your unit by running the self-test.  - This problem invariably relates to a 'heater fault' which has usually been traced to an open solder joint on the control board located behind the switches/indicator lights on front door. If you have a Torx driver, soldering iron & bit of solder, you can effect a repair yourself in about an hour. Otherwise, a replacement control board is required.
If you'd like to attempt replacing the control board yourself, refer to this link for part & DIY information.
- Else, place a service call to the tech of your choice.

Dishwahser rinse cycle running for hours

It sounds like a thermal stop. The water in the rinse wants to get up to a certain temp to satisfy the thermistor but doesn't reach it so it will stay there. If you have an amp probe you can put it on to see if the heater is coming on. This could be your problem.

Do you have high temp rinse or sanitize selected? This will pause the timer during the final rinse cycle to heat the water. The sensor might be bad. Try the quick cycle, I don't think this heats the water.

Bosch dishwasher shu4302uc

Common problem with these. Control panel (behind all the buttons on the door) has a thyristor in the middle of the PCB for switching the heater element ON/OFF.
After many screws and a bit of fiddling about, get access to back of PCB (print side) to find dry joints. Clean and re-make joints and all should be well.
Caution, this is a high voltage area. Disconnect from mains.
Please see photos.
