Compatibility

- AUXXT
- AMX-900
- AMXS-900
- AUXX-1300

It is specifically designed for applications requiring a plug with a width of 17 mm and a length of 69 mm, typically found in boiler sections of these machines.
Installation (Setup)
- Safety First: Ensure the dishwasher is completely powered off and disconnected from the main power supply before beginning any installation or maintenance.
- Locate the Port: Identify the specific opening or port in the dishwasher system where the blanking plug is to be installed. This is typically in the boiler or water circulation system.
- Clean the Area: Thoroughly clean the port area, removing any debris, scale, or old sealant residues to ensure a proper seal.
- Insert the Plug: Carefully insert the Hobart Blanking Plug into the designated port. Apply firm, even pressure.
- Secure the Seal: Depending on the specific dishwasher model and port design, additional securing methods (e.g., a clamp, retaining clip, or sealant) may be required. Refer to your dishwasher's main service manual for specific instructions regarding the port you are sealing.
- Verify Installation: Once installed, visually inspect the plug to ensure it is seated correctly and securely.
- Test for Leaks: After reassembling the dishwasher and restoring power, perform a test cycle and carefully check for any leaks around the newly installed blanking plug.
Note: If you are unsure about any step, consult a qualified service technician.
Operation
The blanking plug is a passive component. Once correctly installed, it functions by sealing an opening within the dishwasher's system. It requires no active operation. Its presence ensures the closed integrity of the system, preventing water or steam leakage from the sealed port during dishwasher operation.
Maintenance
Regular inspection of the blanking plug is recommended as part of routine dishwasher maintenance:
- Visual Inspection: Periodically check the plug for any signs of wear, cracking, or degradation, especially if it is exposed to high temperatures or harsh chemicals.
- Leak Detection: During dishwasher operation, observe the area around the plug for any signs of water drips or steam leaks.
- Replacement: If the plug shows any signs of damage or leakage, it should be replaced immediately with a genuine Hobart replacement part (Model 774808-1) to prevent potential damage to the dishwasher or surrounding environment.
