for models equipped with a drain pump;
verify that the pump is not clogged. if it hums during the fill cycle or rinse cycle then something is lodged inside. If it doesn't then it needs to be replaced.
for models without the drain pump;
something is interfering with the water flow. when the stand pipe is removed, the tank should empty in about one minute.

The detergent system on the Jet-Tech machine are all very similar. Near the solenoid valve under the machine, beside the drain connection, there are two wires, one red and one blue. Those wire will run the detergent pump when the machine calls for water. Two tube are attached to the pump. when looking at the pump from the front or clear plastic can be seen, the tube on the left (arrow going up) is connected to the container with the detergent. the tube on the right (arrow down) is connected to the back of the unit to inject the detergent into the tank. Some precaution should be taken to assure that the connections are tight and not leaking. if the tube shows signs of crystals inside, it should be replaced as the detergent as crystallized within.

On the F-14, the booster thermostat must be satisfied. The rinse thermostat must work properly and or the rinse heater. follow the diagram. This kind of troubleshooting is done by qualified technician. Remember to unplug the unit before opening the panels. It could be just a burnt wire on the rinse booster heater connection.

There is an adjustment for that OR the unit got snagged when it was installed. You need to remove it from under the counter a little and see if it opens all the way. There are pulleys, springs etc near the bottom of the door that adjust that tension. Make sure they are not caught on the cabinets etc.

Check the start capacitor also. The rating of the capacitor will be written on it. Likely to be anywhere from 5uf to 15 uf. If the cap has failed, it wont start the pump properly. If you are having a voltage supply fault, its possible the board has failed.

You will need some skill with tools and knowledge of how your dishwasher operates. First, you will need to remove the back or front panel on the door. This will depend on the kind of dishwasher you have. When opened, look for a metal or plastic arm coming from the dispenser to a motor or gear. This is usually the problem and can be purchased from this site.

That is a water inlet fault. If the tap under the sink is turned on and everything else seems OK then the inlet hose/valve will need to be replaced by a technician
