What ER Means
ER on Frigidaire-built dishwashers is identified in repair references as a membrane switch failure — a stuck key or a key held down too long. Appliance Aid and Parts Town both list it this way.
Common Causes of ER
- Stuck or shorted keypad button
- Moisture under the membrane
- Keypad ribbon cable fault
- Control board fault
🔧 One Safe Check You Can Try
Turn off the breaker, gently wipe the control panel with a slightly damp cloth (no spray directly on the panel), let it dry fully, then restore power. If ER returns right away, book service.
⚠ Why You Shouldn't Go Further Than That
- The keypad is bonded to the console and connects directly to the control board; peeling it loose usually ruins it.
- Moisture problems in the console need the source found, or a new keypad fails too.
- Damage caused during a repair attempt may not be covered by your warranty — check your warranty terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
