Could a failing Main Electronic Control Board cause the GE GTW330ASK4WW to have symptom: Begins to fill lights shut off smell of burning?

The burning smell and loss of display lights indicate that the board's voltage regulator or a high-current triac has experienced a thermal failure. This component manages all power distribution, and a catastrophic short here will immediately terminate the user interface power and emit the reported odor.

Could a failing Lid Lock and Switch Assembly cause the GE GTW330ASK4WW to have symptom: Begins to fill lights shut off smell of burning?

A shorted solenoid within the lid lock is a common root cause for GE control board failure. If the lock fails electrically while attempting to engage at the start of the fill cycle, it can send a voltage spike back to the control board, destroying the logic circuit and causing the machine to shut down.

Could a failing Water Inlet Valve cause the GE GTW330ASK4WW to have symptom: Begins to fill lights shut off smell of burning?

Because the failure occurs specifically as the machine 'begins to fill,' one of the solenoids on the inlet valve may have a shorted internal winding. This causes the solenoid to overheat and smell like burning plastic, while simultaneously potentially overloading the control board's output circuit.

What is the most likely root cause for a GE GTW330ASK4WW with symptom: Begins to fill lights shut off smell of burning?

The burning smell and loss of display lights indicate that the board's voltage regulator or a high-current triac has experienced a thermal failure. This component manages all power distribution, and a catastrophic short here will immediately terminate the user interface power and emit the reported odor.
