TLDR
On your HOBART AM16 DISHWASHERS unit, error code 032 indicates the booster water level failed to reach its target within the allotted time. This usually points to an issue with the incoming water supply, inadequate water pressure, or a fault in the machine's fill system. Promptly check external water connections and supply pressure to restore operation.
Technical Details
Repair Steps:
- Verify Incoming Water Supply: Ensure the main water supply valve to the dishwasher is fully open. A partially closed or completely closed valve will prevent the unit from filling.
- Inspect Fill Hose: Carefully examine the fill hose connecting the water supply to the AM16 for any kinks, twists, or obstructions that could restrict water flow. Straighten any kinks.
- Check Water Pressure: Use a pressure gauge to verify that the incoming water pressure is within the specified range of 15-65 psi (pounds per square inch). Low pressure is a common cause of fill errors.
- Clean Inlet Water Filter/Screen: Power off the dishwasher and locate the inlet water screen or filter, typically found where the water line connects to the machine. Check for any debris, sediment, or scale buildup and clean it thoroughly if clogged.
- Inspect Booster Tank Level Sensor: With the power safely disconnected and locked out, physically inspect the booster tank’s level sensor (which could be a float switch or electrode type). Ensure it’s free of obstructions or heavy scale buildup and can move freely or register correctly.
- Test Fill Valve (Solenoid): If access allows, and with appropriate safety precautions, test the fill valve (solenoid valve) for proper operation. Verify it energizes and opens to allow water flow when the machine attempts to fill. A faulty or sticky valve will prevent water from entering the booster tank.
- Check Electrical Connections: Inspect all wiring connections to the fill valve and the level sensor for any signs of looseness, corrosion, or damage. Secure any loose connections.
- Reset and Monitor: After performing these checks, press the ENTER button on the dishwasher’s control panel to clear the error. Initiate a cycle and monitor closely to see if the booster tank fills correctly and if the error reappears. If the error persists after thorough troubleshooting, the issue may involve the control board or a more complex sensor fault, requiring professional Hobart Service.
Common Questions:
Q: What does “booster water level” mean on my HOBART AM16?
A: The booster water level refers to the heated water in the AM16’s booster tank, which is critical for achieving the sanitizing rinse temperatures (typically 180°F / 82°C) required for health code compliance.
Q: Can low water pressure cause error 032 on my AM16 DISHWASHERS?
A: Yes, insufficient incoming water pressure (below 15 psi) will prevent the booster tank from filling adequately within the machine’s timed cycle, leading to error code 032.
Q: How often should I check my AM16’s water filter?
A: It’s recommended to check and clean the incoming water filter or screen on your HOBART AM16 DISHWASHERS at least weekly, or more frequently in areas with hard water, to prevent flow restrictions and maintain optimal performance.
