Could a failing Dishwasher Heating Element cause the WHIRLPOOL WDT710PAH to have symptom: Error?

The heating element is responsible for elevating water temperature to meet specific wash and rinse parameters. If the resistive coil inside the element develops a fracture or burns out, the water remains cold, and the control board will extend the cycle duration indefinitely while waiting for the thermistor to report the target temperature. This lack of thermal rise eventually triggers the safety 'Error' code and prevents the cycle from advancing to the drying phase.

Could a failing Optical Water Indicator (OWI) Sensor cause the WHIRLPOOL WDT710PAH to have symptom: Error?

This component acts as both a thermistor and a turbidity sensor; it monitors water temperature and clarity. If the lens is obscured by calcium buildup or if the internal thermistor drifts out of calibration, it may report that the water is colder than it actually is or that it is still 'dirty.' The control module responds by extending the wash time and potentially throwing an error when the sensor's feedback contradicts the expected thermal curve.

Could a failing Electronic Control Board cause the WHIRLPOOL WDT710PAH to have symptom: Error?

The control board contains the power relay that completes the circuit to the heating element. If the relay contacts are charred or if the logic gate for the OWI sensor fails, the board cannot effectively manage the thermal cycle. This leads to the symptom of the dishwasher 'hanging' in a specific phase of the cycle and eventually outputting a diagnostic error code due to a logic timeout.
