What F3 E2 (110 / Whirlpool-built) Means
F3 E2 flags the incoming-water temperature sensor on 110-prefix Whirlpool-built Kenmore washers. The documented detail that matters to an owner is that this thermistor is not a standalone part — it comes as a component of the inlet water valve wiring harness.
Common Causes of F3 E2 (110 / Whirlpool-built)
- The thermistor inside the inlet valve harness drifting or failing
- A broken or chafed wire in that harness
- A control board no longer reading the sensor circuit correctly
🔧 One Safe Check You Can Try
Run the hot tap at a nearby sink and see whether hot water arrives at all; a household supply that has gone cold explains a temperature complaint without anything inside the washer being at fault.
⚠ Why You Shouldn't Go Further Than That
- Cut the power at the breaker before anyone opens the console — this circuit is routed alongside live valve wiring.
- Because the sensor ships as part of the valve harness, replacing it is a harness job rather than a small sensor swap.
- A reading taken at the wrong point in the circuit sends the diagnosis to the board when the harness is the real answer.
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.
