My TKD7000 just started acting strangely. As soon as you switch it on, it just starts draining. Even with the door open, and no water left inside. It never stops doing this, no matter how long you leave it. Any ideas please?
Try first unplugging power cord , to check if it clears.
When this happens it is usually the inlet valve in need for replacement.
Also a faulty float switch can give you this problem:
"
There's no water entering the machine
If there's no water entering your dishwasher, check these:
Water-inlet valve
Float switch
Water-inlet valve
The
water-inlet valve lets water enter the machine. If this valve is
defective, you need to completely replace it. It's usually located
behind the lower access panel on the left or right side. It's the
device with the main water line (usually copper) from the house, a
rubber tube to the dishwasher, and two wires attached to it.
Float switch
The
float switch is a small electrical switch that's located right below
the dishwasher "floor." Above the switch, on the inside of the
dishwasher, is a plastic cylinder that floats up as water fills the
dishwasher. If this switch is defective, or if the plastic float gets
caught or trapped in the raised position, the water can't enter the
dishwasher. If the float switch is defective, you need to replace it."

The inlet valve, that is probably the cause for the problem, should be located behind the lower kickplate panel in either the right
or left corner. The panel has a couple of screws to remove it. On some models, the door mustbe opened to
remove the kickplate's screws. Close door before removing panel.

I do not know the exct value for your model, but the valve shows some resistance when it
is functioning properly. If your multimeter reads 37 K it should be ok. Generally when solenoid is bad the multimeter reads infinity.
When you test the valve set your multimeter to the ohms to scale X1.Even if the multimeter does not read infinite the inlet valve may be faulty, and this happens quite commonly.

It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/MOTOR/DRAIN pump/ valve to open up and allow each function to be driven from the flow into the drum as also the drain valve to open to exit the water at the point of the program cycle. If this does not happen then the voltage at the valve/motor/pump must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.
If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. Once the water comes into the system the WATER LEVEL SENSOR - normally a pressure switch- must activate at the preset/chosen level to give the signal to the program controller to switch on the motor. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor for rinse and wash.
Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the dry spin with the drain valve/pump activated so as to drain off all the water from the clothes during the spin.
Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

Thanks for the suggestions. It's already been unplugged for a while, so I will try your other suggestions. The dishwasher is fitted. Does it need to come out it access these parts, or can they be reached from the front? Access does look tricky, to be honest.
Well, I have the inlet valve off. Across the connections is a resistance of 3.7KOhms . Do you think it should be less than that?
