TLDR
On your AM16 DISHWASHERS unit, error code 075 indicates that the machine is not sensing rinse aid for a set number of cycles. This will impact drying performance and spot prevention. To resolve, ensure the rinse aid bottle is full, correctly connected, and then prime the rinse aid pump.
Technical Details
Repair Steps:
- Inspect the Rinse Aid Bottle: First, visually confirm that the rinse aid bottle is not empty. If it is, replace it with a full bottle of Hobart-approved rinse aid.
- Verify Cap and Tube Connection: Ensure that the rinse aid bottle’s cap and the attached suction tube are properly and securely fastened to the bottle. A loose connection can cause air to be drawn instead of rinse aid.
- Prime the Rinse Aid Pump: After refilling or securing connections, press the ENTER button on the control panel. This action will initiate the rinse aid pump priming cycle. Repeat this step as required until the system is fully primed and rinse aid is detected.
- Check for Clogs or Obstructions: If the issue persists, carefully inspect the rinse aid dispense tube for any visible clogs, kinks, or damage. A blockage will prevent the rinse aid from reaching the dispenser.
- Evaluate Rinse Aid Pump Operation: Listen for the rinse aid pump’s operation during a rinse cycle or during priming. If the pump does not actuate or sounds abnormal, it may be faulty and require replacement.
- Inspect Control Board Connections: Power down the dishwasher and disconnect it from the power source. Access the control board and check the electrical connections to the rinse aid pump and level sensor (if applicable) for any looseness or corrosion. Re-secure any suspect connections.
- Calibrate Rinse Aid Dosage (If Applicable): Refer to your Hobart AM16 owner’s manual for instructions on how to check and adjust the rinse aid dosage settings. Incorrect settings can sometimes contribute to detection issues, though less common for a “not sensed” error.
- Consult a Qualified Technician: If all troubleshooting steps fail to resolve error 075, the issue may lie with a faulty rinse aid pump, a malfunctioning level sensor, or a defective control board. Contact a RestoFixer specialist for professional diagnosis and repair.
Common Questions:
Q: Why is rinse aid important for my Hobart AM16 dishwasher?
A: Rinse aid significantly reduces water spotting and promotes faster, more efficient drying of dishes, especially critical in a commercial kitchen for high-quality results.
Q: How often should I check the rinse aid level in my Hobart AM16?
A: It’s best practice to check the rinse aid level daily, or at the start of each shift, especially in busy commercial environments, to prevent unexpected interruptions and ensure consistent performance.
Q: What if the error code 075 persists even after refilling and priming the pump?
A: If the error continues, first reconfirm all connections are secure. Then, inspect the dispense lines for clogs and listen for the pump’s operation. If these checks don’t resolve it, the rinse aid pump, level sensor, or even the control board may be faulty, requiring professional service.
