Won't change cycles

Unplug it then plug again in 5 minutes. It should set it up to factory settings

This may sound odd but might work.

Reset the machine as to start a new cycle. Add 2-4 cups of water. If the machine starts and runs through a cycle then the water inlet valve needs to be replaced.

Good luck

You seem to have inadvertently put it into the test sequence. Try pressing the two reset button simultaneously (usually the reset buttons are 1st and 3rd from left each with a dot underneath, if this does not work, press the button between the two resets (2nd button) P1 should come on then press the right reset button. The unit should run through a test cycle for approx 20mins and eventually reset the module, this is indicated by 0 in the display. Please repost if further assistance required.

see this causes and fix it. God bless you
Thermal Fuse If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work.

Door Switch The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.

Main Control Board The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. YOU should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

Touchpad and Control Panel If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced. On some models the touchpad and control panel are sold together and will need to be replaced at the same time.

Touchpad If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced.

Timer The timer allows power to flow to the proper parts at the proper times. If the dishwasher won't start, the timer might be defective. Keep in mind that timers are often misdiagnosed as the cause of a problem. Check other components first before replacing the timer.

I believe paddy55 is correct about the rack position affecting the rinse agent door. When the top rack is moved to the higher position, the rack hits the latch on the rinse agent door, causing it to pop open.

Move the rack back to the lower position and see if the door stays closed.
