TLDR
On your AM16 DISHWASHERS unit, error 008 indicates the wash tank failed to reach its set temperature within the predetermined time during the fill cycle. This often points to issues with the heating element, water level, or temperature sensor. Initial troubleshooting should focus on verifying proper water fill and the functionality of the heating circuit.
Technical Details
Repair Steps:
- Verify Water Supply and Fill Level: Ensure the dishwasher has adequate water pressure and fills to the correct level in the wash tank. A low water level will prevent proper heating and trigger this error. Check for clogged fill valves or float switches.
- Inspect Heating Elements: Safely disconnect power to the unit. Access the wash tank heating elements. Using a multimeter, check for continuity across the heating element terminals. A lack of continuity indicates a burnt-out or broken element that requires replacement. Also, check for visual signs of damage or scale buildup.
- Test Temperature Sensor (Thermistor/RTD): Locate the wash tank temperature sensor. Disconnect its leads and measure its resistance with a multimeter. Compare the reading to the manufacturer’s specifications or a known good sensor. An incorrect resistance reading or an open circuit indicates a faulty sensor that needs replacing.
- Examine Heating Element Contactor/Relay: With power disconnected, inspect the heating element contactor or relay. Check for burnt contacts, pitting, or any signs of mechanical failure. If the contactor is not engaging properly or its contacts are damaged, the heating elements will not receive power. Test the coil for proper operation if possible.
- Check Main Control Board Outputs: If all other components test good, carefully check for proper voltage output from the main control board to the heating circuit when the heating cycle is active. Exercise extreme caution as this involves live voltage. A lack of appropriate output voltage may indicate a faulty main control board, which would require professional diagnosis and replacement.
Common Questions:
Q: What causes error 008 on a Hobart AM16 Dishwasher?
A: Error 008 typically occurs when the wash tank water does not reach the required temperature setpoint during the fill cycle. Common causes include a malfunctioning heating element, a faulty temperature sensor, insufficient water fill due to a blocked fill valve or low water pressure, or a defective heating element contactor or relay.
Q: Can I reset error 008 on my Hobart AM16 myself?
A: The machine will prompt you to press the ENTER button to clear the error temporarily. However, if the underlying issue (e.g., a bad heating element or sensor) is not resolved, the error will likely persist or reappear, indicating a need for repair rather than just a reset.
Q: What are the most critical parts to check for error 008?
A: The most critical components to check are the wash tank heating elements for continuity, the wash tank temperature sensor (thermistor/RTD) for accurate resistance readings, the heating element contactor/relay for proper operation, and ensuring the dishwasher is filling with adequate water volume.
