Armada dishwasher not working

I'm assuming its a fisher and paykel, you will certainly need more info. Do you have an led display or 3 buttons and lights. Any fault codes, flashing beeping when buttons are pressed etc. If everything is normal no unusual beeps lights etc but nothing AT ALL happens when you press start it is the door 'switch' which is actually a light that is reflected through a plastic prism and back to itself ( originates from the board) check the prism top right drawer frame. Just compare to working drawer. If not more info required.

Try just pressing the selection pad, without pressing start/cancel and close the door. That has worked for me a couple of times.

The only thing that will cause this is a faulty control panel.

No power to the top drawer needs to be verified.

Are you saying the lights are blank and when you press the start buttion nothing happens?

One reason the controller can shut the power is that the heater overload protection thermal resistor has opened. Unfortunately the only way to fix this is to replace the entire heater plate at the bottom of the drawer.

To confirm if the controller is operational or not, press Keylock and Start/ Pause button together for 5 sec (press Keylock first) and see if the Lights light up. If nothing happens then either the power has shutoff as mentioned above or controller is faulty.

It sounds like you have "locked" the dishwasher. This was an added feature that most people never wanted since it only seems to be set by accident.

Try pressing the 3 second button and holding it down for at least three seconds. This should turn the light off. Drove us nuts the first time it happened. If it doesn't turn off then I guess it is broken.

1) Ensure the dishwasher is turned off. 2) (may not apply) Turn the plastic blue lever located under the sink to the vertical position (this opens the valve, so water can go into the dishwasher) 3) Pour powder indo the dishwasher 4) Turn the dishwasher controller to the top position (the 12 o?clock position) ? this is the eco-setting. 5) Press the on/power button on the dishwasher, so that it now turned on (a light will display) 6) Move the dishwasher controller to the ?R? position (it?s on the very left), and leave it there a second or two. 7) Move the dishwasher controller back to the eco-setting (the 12 o?clock position

I suspect for either of these units that the timer control boards are bad.

I just read this for the same problem: push sanitize, then heat and dry, sanitize, heat and dry, sanitize, heat and dry, cancel, then open and close the door. It worked. The dishwasher is running correctly even as I type this.

Try pressing heated wash, heated dry, then heated wash, heated dry. It should reset it. Also try pressing and holding the cancel button for 5 seconds to see if that works if the other doesnt.
