TLDR
On your HOBART AM16 DISHWASHERS unit, error code 006 indicates the wash tank temperature has critically exceeded 239°F/115°C, triggering a safety shutdown. Initially, press and hold the power button for 5 seconds to clear the error and allow the machine to drain. If this overtemperature condition persists, it points to a critical issue with the heating system or temperature sensor, requiring immediate investigation to prevent damage or safety hazards.
Technical Details
Repair Steps:
- Perform Initial Error Reset: Safely power off the HOBART AM16 DISHWASHERS by pressing and holding the power button for 5 seconds. The machine will drain and power off. After the reset, attempt a new wash cycle and observe if the overtemperature condition (Error 006) reoccurs.
- Inspect Wash Tank Temperature Sensor: Disconnect all power to the dishwasher. Locate the wash tank temperature sensor (typically an RTD or NTC thermistor). Visually inspect the sensor and its wiring for any signs of damage, corrosion, or loose connections. Using a multimeter, test the sensor’s resistance and compare it against the manufacturer’s specified temperature-resistance chart. A faulty sensor may provide incorrect readings, causing uncontrolled heating or misreporting.
- Examine Heating Element and Contactor/Relay: With power still disconnected, check the wash tank heating element for proper continuity using a multimeter. Next, inspect the electrical contactor or Solid State Relay (SSR) that controls the heating element. Look for signs of welding, arcing, or carbon buildup, which could indicate a stuck-closed contactor, causing the element to heat continuously without control.
- Verify Main Control Board Functionality: If the temperature sensor, heating element, and contactor/relay all test within specifications, the issue may originate from the main control board. Inspect the board for any visible signs of burnt components, liquid damage, or loose connections. Malfunctions on the control board can lead to improper regulation of the heating circuit. Professional diagnostics are recommended for control board issues.
- Check Water Level and Circulation: Ensure the dishwasher’s wash tank is filling to the correct level. Low water levels combined with heating can cause localized superheating and rapid temperature spikes, leading to an overtemperature error. Verify that the wash pump is operating correctly to ensure proper water circulation during the heating phase.
Common Questions:
Q: What does HOBART AM16 error code 006 signify?
A: Error code 006 on a HOBART AM16 DISHWASHERS means the wash tank temperature has exceeded its safe operating limit of 239°F/115°C, indicating an overtemperature condition that triggers a safety shutdown.
Q: How can I clear the 006 error on my AM16 DISHWASHERS?
A: To clear the error, press and hold the power button for 5 seconds. The machine will drain and power off. If the error persists after this initial reset, further troubleshooting is required.
Q: What are the common causes for a wash tank overtemperature (Error 006) on a HOBART AM16?
A: Common causes include a faulty wash tank temperature sensor, a stuck or welded heating element contactor/relay, or a malfunction on the main control board leading to uncontrolled heating. Low water levels or poor circulation can also contribute.
