What 4-1 / 4-2 / 4-4 / F4E1 / F4E2 / F4E4 (Whirlpool-built HE) Means
The 4-series on Whirlpool-built Kenmore HE dishwashers all report the same break: the electronic control board and the circulation pump motor are no longer communicating. The circulation pump is what drives water to the spray arms, so nothing useful happens while this stands.
Common Causes of 4-1 / 4-2 / 4-4 / F4E1 / F4E2 / F4E4 (Whirlpool-built HE)
- The circulation pump wiring harness unseated or damaged
- A failed circulation pump motor
- A control board no longer driving the pump circuit
🔧 One Safe Check You Can Try
Listen for the pump at the start of a cycle; a machine that fills and then falls silent is behaving exactly as this code describes, and that observation is worth passing on.
⚠ Why You Shouldn't Go Further Than That
- Cut power at the breaker before the base panel comes off; the pump is a mains-voltage component sitting in a wet cabinet.
- The circulation pump is one of the larger parts on this platform, so confirming it against the harness first is worth doing.
- Base panel access may affect any remaining coverage — check your terms before starting.
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.
