ER — Touchpad / Membrane Switch Fault

ER means a touchpad key is stuck or has been held down too long (over a minute), sending a continuous or wrong signal to the control. It's a keypad/membrane switch fault, not a general control-board self-test or memory error.

How to fix it

  1. Check the control panel for anything resting on it or a key that looks visibly depressed; clear it and power-cycle.
  2. Unplug or cut power at the breaker for a few minutes to reset the control, then retry.
  3. Inspect the touchpad for moisture, grease, or residue and clean gently with a dry cloth.
  4. If ER returns and no key is visibly stuck, the touchpad/membrane switch assembly has likely failed internally — replace it.
  5. If replacing the touchpad doesn't clear ER, the main control board may need replacement.

Why it happens

Typical signs: ER on display · Cycle won't start or aborts immediately · One or more touchpad buttons feel unresponsive or sticky · Repeated beeping as if a key is being held down

  • Stuck or physically depressed touchpad key A key is jammed down or something (a magnet, sticker, or object) is resting on the control panel.
  • Key held pressed for longer than a minute The control interprets an extended press as a fault and locks out.
  • Failed touchpad / membrane switch assembly Moisture, grease, or internal wear can cause a key to short internally, sending a continuous signal even with nothing touching it.
