How to tell whether the touchpanel or control board is bad in a Whirlpool dishwasher

whirlpool, dishwasher, keypad and 3 more...
Many times when troubleshooting a Whirlpool-built dishwasher (also sold under the Kenmore and Kitchenaid brands), you'll have a problem that looks like it could be either a bad touchpanel or the control board, but you can't really be sure. Examples include:

- Normal light keeps blinking but the dishwasher won't run
- none of the lights on the panel work and the dishwasher won't run

Could take on lots of other variations but the thing they'll all have in common is that dishwasher won't run.

The conundrum you face is which part to replace: the touchpanel or the control board?

Experience says that it's almost always the touchpanel that goes bad in these cases-- a keypad gets stuck closed or worn on the inside so it no longer makes contact.

Fortunately, there's a way to tell for sure without any guesswork!

Remove the kickpanels below the door and you'll find a tech sheet in a plastic pouch (unless some sleaze bag stole it). Therein it is written this simple procedure for determining whether the touchpanel or control board is the culprit:

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 to check and replace the main circulation impeller in a Bosch dishwasher

While turning the impeller from inside tub have someone else watch the fan blades on the motor with a mirror under the machine.

Most likely you will find when turning the impeller the motor isn't actually turning, thus when motor is running, impeller isn't turning or is only turning very slowly from friction with back portion of impeller which front vane section has broken away from.

Adding a little to this, make sure when turning the impeller from inside the tub area not to push inward with too much pressure while turning because this will shove the two impeller halves back together and possible make the actual motor turn and make you think the impeller is OK when in-fact it is the problem.

Here's the part link for the circulation impeller kit: http://www.repaircli...t/167085/935404

How to reset the control board in a Bosch Ascenta dishwasher

Even in diagnostic mode this models control will happily point toward a problem with the safety float or switch which may not be the problem. Try resetting the control using the following two steps:

1) With the door closed and the dishwasher turned on, press and hold the Start button for 5 seconds. If your model has a display it should show "01" of "00". Press the On/Off button (turning the dishwasher off) and the control should be reset.

2) If step one didn't work, remove the toe kick and disconnect the drain pump wire harness from the drain pump. Make sure the connector isn't touching anything, tape it if necessary. With the door closed, press the On/Off button turning the dishwasher on. You should hear the control turn on and the relays click on and off. Wait about 30 seconds with the power on, then press the On/Off button to turn the dishwasher off. With the power off, reconnect the drain pump harness and reinstall toe kick. With the door closed, press the On/Off button to turn dishwasher on. The control should be reset.

How to run each component in an Asko DW70 dishwasher from the control panel

Posted by Samurai Appliance Repair Man, in Dishwasher Repair 20 June 2013 · 1,683 views
Asko, dishwasher, test and 1 more...
A powerful and indispensable troubleshooting technique to use when working on any modern appliance with a computer control board is to run the self test built into the control board. Almost all control boards used in appliances today have some type of self test. The trick is knowing the key dance to get into it. The other trick is knowing how to interpret the results.

Brother PDuff shares with us the key dance for putting an Asko DW70 dishwasher into self test mode where you can activate each component in the dishwasher individually. This makes quick work of checking each component to see if it's operating correctly.

To access component test:

1) Turn off the main power switch.
2) Wait at least 5 seconds.
3) Press and hold the Program and Start buttons.
4) Switch on the main power switch.
5) Release the Program and Start buttons.

Press Program button to activate component test.
(These components are activated in order after each button press)

1) Inlet valve and mixer valve (mixer valve open 1 second then inlet valve open, after next press of Program button both valves closed then only inlet valve open)
2) Salt water valve
3) Combi dispenser
4) Circulation pump
5) Circulation pump and element
6) Fan and wax motor
7) Drain pump
