Dishwasher has stopping randomly. Yesterday it didn’t drain. When I powered it up and started it to make it drain it did drain but the control panel was flashing and beeping and now won’t do anything. I have noticed it flashing periodically.
Is this a bad control panel and if so where can I get a new one?
For model number LDFN454HT
Hello Farmer, thank you for your inquiry. Based on the description that you have provided, we would recommend checking the door latch first. If it is fine, then the issue could be with the control panel assembly, part number PS16621809. You may need to replace it to fix the issue. Glad to be of help!

When I hit the power button, the lights on the control panel are very dimly lit. The unit will also not power on nor can I press any of the function buttons or start button. Is this an indicator that the control panel is fried?
For model number LDPN6761T
Hi Heath, thank you for reaching out. According to our research, when lights are dimly lit, but nothing responds, it means that the control panel is receiving power, but its internal circuitry or the touchpad itself has failed, often due to moisture intrusion. Replacing the control panel, part number PS16621809, might resolve the issue. We hope this helps.
