I found a burnt solder joint on the control board exactly as you said. I soldered it and now the dishwasher heats up fine. The problem is that it still continuously runs. For example, both the Regular Wash light and the Clean Cycle Progress light remains lit at the same time all the time---it doesn't seem to go through it's cycle. I noticed too that when you take off the control panel that there are two, vertical red lights to the right of the clean light that remain lit all the time. What are they. Any ideas? Thank you.

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.

Soap dispenser door will not open. Regular wash cycle time varying a great deal when machine turned on.


The soap dispenser is probably faulty. Wash times can vary. The main controller will determine the wash time and will change according to water temp when filling, time it takes to fill, etc. Check and make sure the filters at the bottom are clean.

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!

My dishwasher doesn't seem to be washing the


Hello

Water Inlet Valve

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.

Upper or Lower Spray Arm


Your dishwasher has a lower spray arm. It may also have an upper spray arm at the top of the dishwasher. These spray arms are designed to shoot high pressure, high temperature water at your dishes. It is possible that the holes of the spray arms, where the water comes out, are blocked with debris, affecting wash quality. You should inspect your dishwasher's spray arms regularly. Clean out the spray arms as need be.

Heating Element

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.


Filter/Drain Grate

There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishw ashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher. Consult your owner's manual for specific directions for removing your dishwasher's filter and cleaning it.

Detergent or Detergent Cup

It could just be that you aren't using enough soap to completely wash your dishes. Your dishwasher may be designed to dispense soap at two different times during the wash cycle. If you don't fill all of the detergent cups, then the diswasher will lose a cleaning cycle. Also, if you use a gel-type detergent, try switching to a powered kind. Powders tend to dissolve better in hot water. And don't buy in bulk. Detergents are most effective in the first two weeks. After that, they decrease in potency.

Alternatively, your dishwasher's detergent cup could be defective in some way. It is possible that it is gunked up full of built up detergent, and a thorough cleaning may be enough to get it working again. If that doesn't do the trick, you probably need to replace the entire detergent cup assembly. If your cup isn't even opening, please see our section My dishwasher detergent cup won't open.

My dishwasher clean light keeps flashing and wont run. it flashes 7 times and pauses then repeats. whats the issue?


This is an error code.

The error indicates that your dishwasher is failing to heat the water in an allotted time. The error can be caused by numerous issues but the first thing you want to do is reset the control board.

-To reset the control board press: high temp wash, heated dry, High temp wash, heated dry, high temp wash, heated dry, high temp wash, heated dry, high temp wash. If you don't have a "heated dry" button, use the "air dry" or "energy saver dry" button instead.
-All the lights will go solid at which point you press cancel to reset the board.
-If the control board doesn't reset, it's likely that you've just got a faulty control board and the control board will need to be ordered and replaced.
The next step in this process is to start a new cycle and see what happens. If the error code returns, then you'll want to reset the board again and check several things. The most common reasons for this error is because the water coming from your household is just too cold. The dishwasher is expecting 110 degree water to enter your dishwasher, so if your pipes are cold, the water may only come in luke warm. To correct this issue, just run your faucet next to the dishwasher until the water coming out is hot. On another note, make sure the dishwasher is washing with good water pressure. You can put a cup in the upper rack facing upwards and run a cycle to see if it will fill within 10 minutes of starting the cycle. If it doesn't fill with water then you know that the dishwasher isn't producing enough pressure which, in turn, will cause the water to not heat. You'd want to take your pump and motor assembly apart to clean inside if you had a loss of pressure.
You could also have a failed component including a faulty heater, control board, or high limit thermostat. You'd need to uninstall your dishwasher, disconnect power and lay it on it's back to check the resistance of the heater as well as the resistance of the high limit thermostat to confirm if they were bad or good. You should get tangible reading of between 5 and 30 ohms on the heater if it's good and less than one ohm on the high limit thermostat. If both of those devices check good, then replace the control board because that's the one device you cannot test.

Clean light flashes on and off 7 times, then a pause. Then repeats the sequence. Machine will not start regular cycle.


The clean light blinking 7 times can indicate a heater failure.
Press Heated Dry, Normal Washer, Heated Dry, and Normal Wash.
This sequence will run a diagnostic test and clear the error temporarily but if the dishwasher is not heating the water the error will happen again.
If the problem is a reoccurring one then I recommend checking the heater amps if you have access to a clamp-on volt/amp meter.
Remove power to the dishwasher and remove the access panel. See image below. Clamp the meter around the black or white wire at the junction box and restore power and run the test cycle. During the test the heater will come on and the meter should pick up about 8-10 amps. If you get no amp draw then the heater is not working and is the cause of the clean light blinking 7 times

Brand new Matytag MDB7749AWB Dishwasher does not work correctly. As soon as the power was turned on, all three cycle indicator lights ('Wash', 'Dry', and 'Clean') came on and always...


Try putting the unit into a test mode. This my clear your issues otherwise call for service.

One of two ways to do this.
In standby (no lights) Press the combination of buttons:
hi temp wash > sanitize > hi temp wash > sanitize > hi temp wash
All lights will come on and the washer will run a test cycle anywhere from 5 to 10 minutes.
If that button comb doesn't work use:
heated dry > sanitize > heated dry > sanitize > heated dry

Blinking Clean light in Whirpool dishwasher


Control is programmed to stop running and not allow any further cycles if it detects a water heating problem (no temperature increase detected in heated Main Wash on 3 consecutive cycles). Control blinks the Clean LED 7 times repeatedly and disables the Start/Resume key until cleared. Running Diagnostics clears the control and allows it to operate again. The water heating problem must be fixed or the control will stop running again. See potential causes below. Heater circuit problem: ■ Open in heater. ■ Open connection or component in heater circuit. ■ Faulty heater drive circuit on control. 1. Check operation of heater in Diagnostics cycle. 2. Unplug dishwasher or disconnect power. 3. Check resistance of heater and all components and connections in the water heating circuit or heat dry circuit.

What is the amount of time for a regular wash? Time on the plus wash?


a regular wash should take about an hour and a half. plus wash would be longer only because it heats the wash temp hotter.
wash temp is generally around 140 degrees
and your rinse is around 161 degrees.

your flow through heat assembly heats the water at 2 degrees a minute. so it can take anywhere from and hour and a half to two hours for a full cycle.
try turning your sink on hot water until you feel hot water coming out then start the dishwasher so it doesnt have to heat cold water up to those temps. it should run a little shorter.
