Hello, Thank you for using this service, I will be helping you with your problem today
if your sure the module you bought was good the only other thing that could be bad would be the touch pad(keypad) itself. its shorted.you would need to replace it.was the module you replaced new ?
This happened once before and I replaced the module. The keypad behaved exactly the same way...the dishwasher beeps when the door is shut and the keypad lights up although the lights don't come on properly when you press them. Open the door and the keypad is unresponsive. I got the module off Ebay from a parts store rather than an individual, but off course, there is no returns...
Thanks! I couldn't see anything else that it could be, but I am not an expert so I wanted to check before I bought another one. Thanks for the referral for the part WITH the return policy!
