TLDR
On your HOBART AM16 DISHWASHERS unit, error code 014 signifies that the maximum booster water level has been exceeded, causing the machine to halt operation. This issue commonly points to a malfunctioning booster pressure sensor or a stuck-open water fill valve. Begin by attempting to clear the error as instructed by the machine, then proceed with inspecting the water fill system components.
Technical Details
Repair Steps:
- Initial Error Reset: According to the machine’s instructions, press and hold the power button for 5 seconds to clear the error. The machine should drain and power off. If this resolves the issue, monitor subsequent wash cycles.
- Verify Incoming Water Pressure: Ensure the cold water supply pressure to the dishwasher is within the manufacturer’s recommended range. Excessively high or fluctuating incoming water pressure can sometimes lead to overfilling the booster tank if the fill valve cannot adequately regulate the flow.
- Inspect Booster Fill Valve: Locate the water inlet solenoid valve responsible for filling the booster heater tank. With the machine powered off and locked out, visually inspect the valve. Check for any signs of leakage, or if it’s mechanically stuck in an open or partially open position, allowing continuous water flow. A faulty solenoid valve can cause the booster tank to overfill. Replace the booster fill valve if it is found to be defective.
- Examine Booster Level/Pressure Sensor: The error description mentions a “Booster pressure sensor failure.” Locate the pressure sensor (or a float switch/level electrode, depending on your AM16’s specific configuration) that monitors the water level within the booster tank.
- Wiring and Connections: Disconnect the sensor’s wiring and inspect all terminals for corrosion, damage, or loose connections. Re-secure any loose wiring.
- Sensor Integrity: If it’s a pressure sensor, check for any blockages in its sensing tube. If it’s a float switch, ensure the float mechanism moves freely and isn’t obstructed or damaged.
- Test Sensor: If possible, test the sensor’s continuity or resistance using a multimeter, referencing the HOBART AM16 service manual for specific values. Replace the booster level/pressure sensor if it tests faulty.
- Check Wiring Harness: Carefully trace the wiring from both the booster fill valve and the booster level/pressure sensor back to the main control board. Look for any visible signs of damage such as cuts, pinches, chafing, or signs of heat stress. Repair or replace any compromised sections of the wiring harness.
- Inspect Main Control Board: If all external components and wiring appear to be in good working order, the issue might stem from the main control board. A faulty input circuit on the board that monitors the booster level sensor or controls the fill valve can cause this error. Visually inspect the main control board for any burnt components, swollen capacitors, or signs of water damage. Diagnosis and replacement of control boards typically require a qualified HOBART service technician.
Common Questions:
Q: What does HOBART AM16 DISHWASHERS error code 014 mean?
A: Error code 014 on a HOBART AM16 DISHWASHERS indicates that the water level in the booster heater tank has exceeded its maximum allowable limit, which stops the machine from running to prevent potential overflow or damage.
Q: Can I clear error 014 myself on my Hobart AM16?
A: Yes, the machine provides an initial reset procedure. You can press and hold the power button for 5 seconds, which should drain the machine and power it off. If the error persists after this reset, further troubleshooting is required.
Q: What components are typically responsible for a “booster pressure sensor failure”?
A: The most common culprits for this error are a faulty booster pressure sensor (or level sensor/float switch) itself, or a water inlet solenoid valve for the booster tank that is stuck open or leaking, allowing continuous filling beyond the set limit.
