PROBLEM: Won't Run and LED Above Key(s) is Flashing Rapidly


Short circuit(s) in keypad or


in control's input lines that


read the keys.


Don't replace both:

See first section of


"Checking Keypad Operation" for test to


determine whether shorts are in the


keypad or the control.

 

 

CHECKING KEYPAD

OPERATION

 

A rapidly blinking LED over

 

one of the keys of the keypad

 

(or sometimes a "dead"

 

keypad/console) indicates one

 

or more key switch lines are

 

stuck or shorted on either the

 

control or the keypad. To

 

determine if the control or

 

keypad is faulty, do the

 

following test:

 

1.

Unplug dishwasher or disconnect

 

power.

 

2.

Open the dishwasher door.

 

3.

Open console and disconnect the

 

keypad ribbon connection from

 

the control (at P1). Make sure all

 

other connections are made.

 

4.

Put console back together. Do not

 

close the dishwasher door.

 

5.

Plug in dishwasher or reconnect

 

power.

 

6.

Wait 5 seconds.

 

7.

Close dishwasher door.

 

8.

Monitor the control's response:

 

If the control is OK (no longer

 

sees shorts with the keypad

 

unplugged), it will respond by

 

turning on a Drain Motor for

 

2 minutes. Check and/or

 

replace the keypad if the

 

control responds OK.

 

If the control is not OK (still

 

sees shorts with the keypad

 

unplugged), then the drain

 

motor will NOT respond and

 

will remain off. If no response,

 

replace the control.

How do I open console? Remove whole front of door?

around the inside of the door there are screws, remove them and lift the inner door panel up. On some of these you just remove the ones near the top and the control will come off without removing the whole inner panel.

Customer: replied 3 years ago.

14 screws, no separate panel, will have to take off whole door.But that is it, either replace the control or the keypad? any ballpark figure on what each costs? is it cheaper to replace dishwasher?

yes I do have the prices, the control board is $126.00 Control Board(NNN) NNN-NNNNMain Product View and the keypad is $124.00 Touchpad and Control Panel(NNN) NNN-NNNN        Main Product View now the links are below to order and they have a full money back guaranty even if you install them. heres the links. CONTROL KEYPAD just click whichever you need. thanks and have a great night, Bryan
