Ariston Oven Error Code ER06

ER06 on an Ariston oven means the PTC temperature sensor in the oven cavity has been detected as short circuited. The PTC sensor monitors oven temperature and at room temperature should read approximately 545 ohms resistance. A short circuit causes the resistance to drop to an abnormal level, which the control board interprets as a fault and halts normal operation.

It is not recommended to continue using the oven while ER06 is active. A shorted temperature sensor means the oven's control system cannot accurately monitor the internal temperature, which could lead to overheating, inconsistent cooking results, or further damage to control components. The oven should be kept switched off until the fault is diagnosed and repaired.

A power reset by switching the oven off at the circuit breaker for a few minutes may temporarily clear the ER06 display, but the error will return as soon as the control board reads the shorted sensor again. Because ER06 indicates a hardware fault in the PTC sensor or its wiring, the underlying problem must be physically repaired or the component replaced before the error will be permanently resolved.

A knowledgeable DIYer comfortable with basic electrical testing can diagnose ER06 by using a multimeter to measure the resistance of the PTC sensor at its terminals, comparing the reading to the expected 545 ohms at ambient temperature. If the sensor reads significantly lower or near zero, it needs to be replaced. The wiring harness and connectors should also be inspected for damage. If you are not comfortable working with oven wiring, a qualified appliance technician should perform the repair.

If only the PTC sensor requires replacement, parts costs are typically in the range of $20 to $60 depending on the specific model, with labor adding $80 to $150 if a technician performs the work. If the wiring harness or control board is also found to be faulty, total repair costs can rise to $150 to $350 or more. Getting a diagnostic quote before committing to repairs is advisable.
