Frigidaire Dishwasher Error Code ER-02 — Stuck Button / Touchpad Key Fault
What this means
The ER-02 error code on Frigidaire dishwashers means the touchpad or control panel is registering a key press that was not made by the user. This can be caused by a worn membrane switch, moisture trapped behind the panel, a stuck physical button, or a failing UI board. The dishwasher may beep continuously or refuse to accept inputs.
Alternate codes: ER 02, i02
Step-by-step fix
4 stepsReset the dishwasher
Turn off the breaker for 5 minutes. Restore power. If the error clears and the buttons respond normally, moisture or a momentary glitch caused the false signal.
Steam from a recently completed hot cycle can condense behind the touchpad and cause phantom key presses.
Clean the control panel
Wipe the entire touchpad area with a soft, slightly damp cloth. Dried food, detergent residue, or grease can create conductive bridges between button contacts.
Do not spray cleaner directly on the panel — moisture can seep behind it and make the problem worse.
Check for physically stuck buttons
Press each button on the panel individually. If any button feels stuck, is recessed, or does not spring back, it may be mechanically jammed. Gently work it loose.
Food splatter can work its way into the edges of buttons and cause them to stick.
Replace the touchpad or UI board
If the error returns after cleaning and no button is physically stuck, the membrane switch or UI board has failed. Turn off the breaker, remove the door panel, and replace the UI board or touchpad assembly.
On many Frigidaire models, the touchpad and UI board are sold as a combined unit.
When to call a professional
If the UI board replacement does not resolve the error, the main control board may have a faulty key matrix input. A technician can diagnose the circuit.
