Dishwasher runs forever

In the morning I turn my dish washer on the digital time reads 1:37 but it runs for about 4 hours. I was having a problem with the hot water but we had that fixed and it is very very hot.

Hello, welcome to Fixya. What you're describing sounds like a bad control. If the water at your water supply is indeed hot it shouldn't be an issue, however you can try running the hot water at your sink tap to insure the cold water is out of the lines just before you turn on the dishwasher. If it is what I suspect, the control, this won't make any difference but it's worth a try. If on the other hand the water is good and hot entering the machine, you likely have an issue with the control as I alluded to. repairclinic.com carries them as part # 1102296 at a retail price of $185.65US. as I type this today June 2,2010. however, I have a suggestion as to identifying the culprit, thus confirming or dismissing the cause... since the issue with your Bosch dishwasher potentially lye`s within`the electronic timer/control, specifically the heater relay solder joint. You'll need to access the control for a visual inspection ( a faulty flow switch, ntc or heater can also cause this, but not very probable ). This is possibly one of the reasons why it runs for 4hrs or more (unless pressing the two buttons for "cancel"). To inspect and possibly repair your unit It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit runs & runs ( because it can`t heat to advance or until canceled ) trying to heat the water. **Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)** **Please disconnect the power before attempting any service to the dishwasher. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau, to service your machine.** Hope this answer`s your question's, let me know if I can assist you further. I will look for your reply. Please do reply either way, I've found after answering many of these questions I'm left wondering if the info was of any use to those asking. Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness to you and leave a testimony if you're satisfied. Good luck. macmarkus :)

I would like to add a comment but can't figure out how......

my dishwasher runs in the drain cycle and wont advance. it runs even with the door open. it turns on and off just fine, but again runs with the door open. i'm guessing it is a problem with the control board as discussed above. later today i will remove it and inspect for burnt solder contacts, hopefully i will find something. if anyone has another solution, please post. i will post my findings.
thx,
Tim

Dishes won't come clean


Check your water inlet for the right pressure and then the water float valve for the right amount of water in the tub for washing. The tub has to have the right amount of water in it to pump it up to the top. It is also possible that the pump has debris in it that is restricting the flow. Clean out the screens and check the bottom of the washer tub for debris at the pump inlet. Use white vinegar to clean out your washer. Start your washer - open the door and pour in a lot of vinegar. Let it run for a few seconds and stop it. Let the vinegar work on the scale and debris. Start and stop it several times during the day - not completing the wash cycle until in the morning - after it has sat with the vinegar 10 -12 hours.

Dishes not cleaning after full cycle running


Your screens are plugged with food residue in the bottom of the unit. clean it out. You can use 1 gallon of white vinegar for your wash after you clean the screens. Start your washer to fill with water but after the water starts, open your door and pore all of the gallon in the unit. Let it now run for 4 minutes and stop it by opening the door. Leave the door slightly open for 1 hour. close the door and let the cycle continue for 4 more minutes. open the door and repeat it a couple of more times. Let it sit all night with the vinegar in it and in the morning - close the door and let the cycle continue to the end. This should help soften and clean out the food particles in the unit. You can repeat the process and get a better cleaning then too. All the scale should be off your dishes now.

there is a "smartclean" sensor that measures dissolved solids in the water in an attempt to shorten the washing cycle. however if the dishes have much food left on them, then the washer will continue to run untill it gets a "clean" reading, or it reaches the max run time (180 minutes). all energy star dishwasher require the dishes to be throughly rinsed before washing in the machine. trust me, i know how counterproductive this is.

Ran for 12 hours before we shut it off?


Probably the timer has failed. It is stuck but can't be fixed. Not difficult to replace.

Will not fill up with water before starting, it takes about 3-4 times brfore unit will run with full amount of water. loads take forever.


dish washers have a fill valve. the water supply line most likly has a net like filter that is stoped up with trash. Or fill valve is bad.
same thing happens to washing mashines. when they start filling up very slow you will TURN OFF water supply and diconect hose, look inside and there is the problem.

I have a bosch dishwasher shu6805uc/u06 to long to wash.


Well not going into the dry cycle could be a timing issue or a EOC (control panel) issue and will need to be addressed. But most dishwashers these days have a active run time during normal cycle of 110 to 120 mins, and thats not including the heated dry feature. I would let the unit run and see if it will finish on its own, and if I say it pushes two and half hours then something is wrong. A tech would most likely have to look at it, also a power reset could help but thats like a 30% chance.

Frigidaire FDB710LCS0 Dishwasher dial seems to stick?


I had the same problem. Turn the HIGH TEMP buttons off. Simply turning them off corrected this problem for me. Mine got stuck in two places and I had to manually turn the dials or the washer would run all night.
