Common solutions for Frigidaire dishwasher lights blinking?

Heating Element

The heating element warms the water to a temperature that is operating. If the water isn’t at the correct temperature within the specified time, the indicator light in the panel may begin flashing.

Drain Pump

The drain pump utilizes an impeller to push liquid through the drain line. When the pump isn’t functioning, the warning light from the controller could begin flashing.

To find out if the drain pump is inoperable, examine the motor’s continuity with an instrument. If the motor doesn’t have continuity, you must replace your drain pump. Drain pumps aren’t repairable.


The first step is to confirm that the display is functioning. If it is functioning, try pressing a few of the buttons on the touchpad. If some buttons work, but the rest do not, it’s most likely the touchpad has failed.

(Some companies sell the touchpad in separate packages in addition to the control panel. Others require you to purchase the control panel in tandem. If you can’t replace the touchpad by itself, you must replace both the touchpad and control panel together.)

The problem may be due to an issue within the control panel. Try these suggestions (if you are confident enough to take an issue with fixing the control panel by yourself):

The control panel can be opened through the front panel. take care to remove any corrosion from the connectors for ribbon cables (check the cable connecting to the screen). Be sure to make sure that all connections are tightened (the problem could be due to an unreliable connector to your panel).

Replace the control panel sometimes the whole panel may be broken and requires to be replaced in order for the unit to begin working once again.

Quick Tips: In some cases, the control panel, as well as the touchpad, need to be replaced to eliminate the issue.
