TLDR
On your AM16 DISHWASHERS unit, ASR overflowing indicates a blockage or malfunction within the Advanced Scrapping System or its drainage. This typically results from a clogged drain line, a dirty ASR basket, or incorrect installation of ASR components, impairing the dishwasher's pre-wash and debris removal capabilities.
Technical Details
Repair Steps:
- Inspect the Drain Line for Obstructions: Carefully check the main drain line connected to your HOBART AM16 for any kinks, twists, or internal blockages. Disconnect the drain hose from the building’s drainage system and visually inspect it for food debris, grease, or foreign objects. Use a plumber’s snake or a stiff brush if necessary to clear any suspected clogs. Ensure proper reconnection to prevent leaks.
- Clean and Reinstall the ASR Basket: Power off and lockout the dishwasher. Open the door and locate the ASR basket (Advanced Scrapping System basket). Remove it and thoroughly clean all accumulated food debris, grease, and foreign objects. Inspect the basket for any damage or deformation. Also, clean the cavity where the ASR basket sits, ensuring any underlying drain ports are clear. Carefully reinstall the ASR basket, making sure it is correctly seated and locked into position according to the manufacturer’s instructions. An improperly seated basket can cause water to bypass the system and overflow.
- Check ASR Nozzles and Filters: If your HOBART AM16 model features additional spray nozzles or filters within the ASR system, inspect these components for blockages caused by food particles. Remove and clean any clogged nozzles or screen filters to ensure optimal water flow and debris capture. Reinstall all parts securely after cleaning.
- Verify Water Levels and Overflow Sensor (If Applicable): Run a short wash cycle and observe the water levels within the wash tank. An overfill condition, though less common for direct ASR overflowing, could contribute to the problem. If persistent overfilling is observed, consult your unit’s manual for water level sensor location and testing, or contact a qualified technician.
- Professional Inspection: If the ASR system continues to overflow after performing these troubleshooting steps, there may be a more complex underlying issue. This could include a malfunction with the ASR pump, a deeper blockage in the internal plumbing, or a faulty sensor. In such cases, it is recommended to contact a certified HOBART service technician for a thorough diagnosis and repair.
Common Questions:
Q: What is the ASR system in a HOBART AM16 dishwasher?
A: The ASR (Advanced Scrapping System) in a HOBART AM16 is a pre-wash debris removal system designed to automatically filter out larger food particles before they enter the main wash tank, improving wash quality and extending the life of the wash water.
Q: Why is my ASR basket overflowing even after I cleaned it?
A: If the ASR basket continues to overflow after cleaning, the primary drain line from the dishwasher might still be partially or completely clogged further down, or the basket itself might not be seated correctly, allowing water to bypass it. Re-check the main drain and basket installation carefully.
Q: Can I run my HOBART AM16 without the ASR system if it keeps overflowing?
A: Operating the machine with a malfunctioning or overflowing ASR system is not recommended as it can lead to poor wash results, unsanitary conditions, and potential damage to the dishwasher due to frequent draining issues. It’s best to resolve the ASR issue before continued use.
