Frigidaire dishwasher touchpad not working
Here’s what you should do to get your Frigidaire dishwasher control panel up and working again…
Clean the dishwasher components
At times, your dishwasher is simply unresponsive due to debris being stuck in one part or the other of the dishwasher.
To begin with, clean the door latch assembly.
Here’s the thing, debris trapped inside the latch assembly might result in your dishwasher flashing lights and a frozen control panel.
Still on the same, it could be that some gunk has found its way into the UI pad or to the control board.
That being so, take out the touchpad and the control board.
If they are dirty, proceed to cleaning them using isopropyl alcohol or any other electronic contact cleaner and let the parts dry fully before reconnecting them.
Quick tip: you can use a toothbrush to scrub off any gunk that is not coming off.
Something else: water might have found its way to the control board.
If you note that this is the case with your dishwasher, take out the control board and air dry it.
Once you reconnect the board, make sure that your dishwasher’s touchpad is completely under the counter when the door is closed.
This should prevent the water from finding its way to the board again.
Inspect the wire connectors to the control board
Start by confirming that the two wire connectors between the control board and the touch screen are well inserted in place.
If not, remove and properly reconnect them.
Another thing, if any of the connectors has scorch marks, then, the connector is faulty and will require to be replaced.
If you opt to replace the wire harness, we recommend Frigidaire’s OEM dishwasher wire harness kit (you can order on Amazon).
Next, carefully inspect the ribbon cables connecting these wire connectors for hairline cracks.
Again, if any of the ribbon cables has cracks, it will need to be replaced.
Test the power supply within the dishwasher
Other times, it could simply be that your dishwasher is not getting enough power – typically, dishwashers require 120v AC.
Bearing that in mind, first confirm that the voltage from the power outlet is within this range.
If it’s not, connect your dishwasher to another working outlet and have an electrician have a look at the current outlet.
On the other hand, if the voltage is within the 120v AC range, proceed to testing the power at the control board.
For this, insert the probes into P3-5 (black) and P3-6 (white) – if you don’t get a reading of 120v AC, inspect for a loose connection within the unit.
For the most part, the neutral wire in Frigidaire dishwashers is notorious for working itself loose at the latch. So, be sure to check this out too.
On the other hand, if the voltage is okay, proceed to the test below…
Replace the touch pad
Other times, it could be that the touchpad has failed.
This might be due to a visible damage or an internal electrical fault.
Bearing that in mind, you will want to replace the panel as this might be the solution to getting your unit running again- we recommend Frigidaire’s OEM dishwasher touchpad (order the replacement part on Amazon).
Remember that OEM parts will fit well on your dishwasher and they generally outlive their generic counterparts.
Inspect the control board for signs of damage
Finally, it could be that your touchpad is not responding due to a faulty control board.
However, unlike other parts, there is no way to directly test the control board for faults.
Instead, you will need to rely on visual inspections.
Bearing that in mind, carefully inspect the board for scorch marks or any other marks that might point to a faulty board.
Quick tip: it would not hurt to reset your dishwasher before swapping out the board. To reset the dishwasher, simply unplug it from the power outlet and let it sit for five minutes.
If there are scorch marks around the capacitors (or the above steps do not fix your dishwasher), replacing the control board might be your only fix.
If you opt to go this way, we recommend Frigidaire’s OEM dishwasher control board – part #5304501595.
