Customer Questions and Answers for Dishwasher Electronic Control Board by Whirlpool

Matt, You're blinking light issue is more likely due to a faulty keypad / control panel WPW10199788. " 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 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 sec. 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 the 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 if the drain motor does not start within 10 sec, repeat or verify that all the steps were followed, then replace the control." Thanks and Good Luck
