Re: 2 hour run time

One needs to take into concideration how long it takes for the water to enter the unit and how long it takes for the water to heat up.these factors will influence the running time. defective heater very common.

Dishwasher takes 3 hours to run through programme

3 hours isn't "extremely" long. If you run a normal cycle, it should run about 2-2:30 hours normally with the drying cycle. Now if it's over 3 hours, that would be a problem. Make sure that when you open the door that there is a lot of steam coming out, because that is the only thing that can extend the cycle is if the dishwasher isn't heating the water. Unfortunately this is a very common issue and it means that your control board inside the door has failed. There is a relay on the board that shorts out. This relay sends power to the heater, so when it fails the dishwasher doesn't wash well and it will run forever trying to heat the water which will never happen.

My diswasher runs for 2 hours I would like for it to run less than 2 hours

To make it run for less time, you will have to change your settings.

Is it true that it takes about 2 1/2 hours to go through a normal cycle? If not, how long does it take, approximately? I am asking about the 18 inch built-in.

I cannot find any mention of times for this particular machines run, I have found the Users Manual HERE. I don't think it should take 2 1/2 hours to run this unit through a cycle, perhaps 30 minutes to one hour.
I hope this answers your query.

Bosch SHX33A05UC/36 dishwasher seems to run for hours to do a load of dishes. Checked water temperature, drain and hose and all is clean. The rinse and hold cycle times out correctly. Is it a timer or...

No, the problem in not the unit, it is programed to run up to 3-3 1/2 hours for a single cycle. You can select quick wash to shorten this time down, but this is not a problem with the unit. It wants to assure you have clean dishes and hot enough water to complete the program.
In testing one a few days ago, I ran into this same problem, I reread the time charts and cycles and found this to be normal for this manufacture.
I hope this answered your question.

The dishwasher runs for 2 hours. How can I fix

Check your water inflow to the machine. If it is not filling the machine it may take time. Check the wash programme setting- like light, heavy, soiled etc.( depends on the m/c design)

Bosch SHX46A05UC/30 runs for 4 hours.

The circut board in the biege plastic case under the buttons on the right has what is called a cold solder. In other words the solder melts under operational use. Some are repairable and some are not.

1. UNPLUG DISHWASHER or turn off breaker and test for electricity.
2. Remove screws from door panel.
3. Take pic of position of wires going into plastic box.
4. Remove top section of plastic box with buttons exposing small circut board.
5. Open plastic box exposing large circut board and in the middle of it you will see a black spot where the solder has popped. Resolder and reassemble OR replace old circut board and then reassemble.

A new circut board is about $135
Usually electrical parts are not returnable

Problem with Bosch built-in Dishwasher Model SHU6806UC

I had the same problem and just today replaced the control board module. Purchased the control module online and installed in myself. Was not that difficult. undo the screws (torx screw driver needed) unhook the connections to the board and label all. Pull the board out and open, found burned connectors. Now works like a dream.
