SOURCE: Dishwasher does not clean dishes, soap does not fully go away
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.
Heating Element
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.
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.
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, My dishwasher detergent cup won't open.
Cycle Selector Switch
Sometimes a dishwasher's cycle selector switch is the reason why dishes are not coming completely clean. Test your selector switch to determine whether or not it has become defective. If it has, replace it.
SOURCE: Detergent Dispenser does not open
It is located within the door assembly, close to the detergent dispenser cup. You will need to gain access to the inside of the door.

Tarvi...I don't know what the problem is...hard to diagnose these things. If the unit is working correctly, I suggest that you simply cut the power for a few minutes and then restart it. That may clear our a trouble code.

Hi,
I have just had my dishwasher fixed by Hotpoint, as the heater was working and the dishwasher only stopped with the fast and delicate lights just before the drying process he replaced the main control board. This has solved the problem, I suspected the fault to be the thermistor as the heater seemed to be getting to hot but I had no idea where it was.
It turns out the thermistor is attached to the main control board and hangs down behind the front door that gives just a rough temperature level for the main control board.
As it's soldered directly onto the control board I would suggest replacing the whole control pcb for anyone with this fault unless you can find any spec details for the thermistor.

Is the clean light blinking 7 times? If so this means you have a problem with your heating element
Hello Theresa Norman-Ramirez - Typically, it is normal for the dishwasher to delay the cycle and depending on the cycle and options selected, the cycle may last up to 4 hours. To reduce cycle time, turn on the hot water at the sink and allow it to get as hot as possible (between 120 F-130 F), then start the dishwasher. If the dishwasher cycle runs longer than 4 hours the main control board may need replacing. I would suggest contacting an experienced service technician to determine the precise cause.
