Possible Causes
Debris or moisture under keypad, Worn or damaged membrane switch, Shorted keypad circuit, Topside panel failure
How to Fix / Troubleshooting
Safety first: Turn off power before attempting any cleaning around the topside panel.
- Inspect keypad surface: Look for visible damage, cracks, or debris around the buttons.
- Clean gently: Wipe the keypad with a soft, slightly damp cloth. Do not flood the panel with water or cleaners.
- Test buttons: After drying, restore power and test each button. If Er2 persists or certain buttons do not respond, the panel membrane is likely failing.
- Replace topside panel: Order a compatible Aquaterra Spas topside control and install according to manufacturer instructions, ensuring a proper gasket seal to prevent future moisture intrusion.
If a new panel does not resolve Er2, the control board keypad interface may be defective.
