TLDR
On your AM16 DISHWASHERS unit, error code 038 indicates that the incoming power supply voltage exceeds the maximum allowable limit, causing the machine to automatically shut down for safety. This prevents potential damage to internal components. Immediately verify the electrical supply and unit's wiring.
Technical Details
Repair Steps:
- Safety First: Turn off the main circuit breaker supplying power to the HOBART AM16 DISHWASHERS before any inspection or troubleshooting. Use a multimeter to confirm power is completely off.
- Check Machine Data Plate: Locate the data plate on your HOBART AM16 DISHWASHERS (typically on the inside of the access panel or rear) to confirm the exact specified voltage requirements (e.g., 208V, 240V, 480V, 3-phase). Note this required voltage.
- Measure Incoming Voltage: With the circuit breaker off, use a multimeter set to the appropriate AC voltage range to measure the voltage at the main disconnect switch or the connection point where the dishwasher power cable connects to the building supply.
- Identify Voltage Discrepancy: Compare the measured voltage reading with the voltage listed on the machine’s data plate. If the measured voltage significantly exceeds the machine’s specified maximum voltage, the issue is with the building’s electrical supply or an incorrect power connection.
- Consult a Certified Electrician: If the incoming voltage is indeed too high, it is critical to contact a certified electrician immediately. They must assess and correct the building’s electrical supply to ensure it matches the dishwasher’s requirements. Do NOT attempt to power the machine with an incorrect voltage.
- Verify Wiring (Electrician): Ensure the dishwasher is correctly wired for its specific voltage configuration (e.g., delta vs. wye for 3-phase, correct connections for single-phase). This step must be performed by a qualified technician or electrician.
- Reset Error: Once the power supply issue has been safely resolved and verified by a qualified electrician, restore power to the circuit breaker. The machine should then allow you to press “Enter” (or the equivalent clear button) to clear the error code and attempt normal operation.
Common Questions:
Q: Why did my HOBART AM16 suddenly display error 038?
A: This error often occurs due to fluctuations in the building’s main power supply, a phase imbalance (for 3-phase units), or if the machine was recently moved or connected to an incompatible power source. It’s a safety shutdown.
Q: Can I ignore error 038 and continue using the dishwasher?
A: No, it is critical not to ignore error 038. Operating the HOBART AM16 DISHWASHERS with an over-voltage condition can severely damage expensive electronic components (PCBs, motors, heating elements) and poses a significant safety risk. The machine shuts down to prevent this.
Q: How can I prevent this over-voltage error in the future?
A: Ensure your dishwasher is connected to a stable and correctly rated power supply. Consider installing a voltage monitoring device or surge protector if your facility experiences frequent power fluctuations. Regular electrical system checks by a qualified electrician can also help maintain stability.
