Frigidaire Washer Error Code E68

Error code E68 on a Frigidaire washer indicates that the control board has detected either a current leakage to ground on the heating element circuit, or that the thermal fuse protecting that circuit has opened. The heating element is responsible for raising the water temperature during wash cycles that require heated water. When current escapes the element's intended path and flows to the machine's ground, it signals an insulation breakdown within the element itself. Alternatively, if the thermal fuse has opened, it means the circuit experienced an overcurrent or overtemperature condition that caused the fuse to sacrifice itself to protect the wiring and control components.

The primary diagnostic step is to measure the resistance of the heating element directly. A properly functioning heating element should measure approximately 14 ohms. A reading significantly higher than 14 ohms, a reading of infinity (open circuit), or a reading near zero (short circuit) all confirm element failure. An open circuit reading specifically suggests the thermal fuse within the element assembly has blown. A near-zero reading between the element terminals and the machine chassis would confirm a ground fault condition, consistent with the current leakage description in this code.

This fault is both a performance issue and a safety concern. A ground fault on a heating circuit means electrical current may be traveling through unintended paths, which can pose a shock hazard and may trip a GFCI outlet if the washer is connected to one. The washer will typically suspend the heating function or halt the cycle entirely when E68 is triggered, preventing potential damage to other electrical components.
