TLDR
On your HOBART LXn/LXGn SERIES DISHWASHERS unit, error code 079 indicates that sanitizer has not been detected for three consecutive cycles, leading to a machine lockout. This usually points to an empty sanitizer bottle, an improperly secured cap or tube, or an issue with the sanitizer pump. To resolve this, ensure the sanitizer bottle is full and correctly connected, then prime the sanitizer pump.
Technical Details
Repair Steps:
- Inspect Sanitizer Bottle: First, visually confirm that the sanitizer bottle is not empty. If it is low or empty, replace it with a full bottle of the recommended sanitizer.
- Check Cap and Tube Connections: Ensure the cap on the sanitizer bottle is securely fastened and that the suction tube is properly inserted and seated at the bottom of the bottle. A loose connection can cause air to be drawn instead of sanitizer.
- Prime the Sanitizer Pump: After replacing or securing the sanitizer bottle, press the ENTER button on your LXn/LXGn dishwasher’s control panel. This action primes the sanitizer pump, drawing sanitizer through the tube and into the system. You may need to repeat this step a few times until sanitizer is visible in the line or the error clears.
- Run a Test Cycle: Once the pump has been primed, attempt to start a wash cycle. Monitor the machine to see if the error clears and if sanitizer is being dispensed.
- Verify Sanitizer Dosage (If Error Persists): If the error continues after ensuring the bottle is full, connections are secure, and the pump is primed, the issue might be a clogged sanitizer line, a faulty sanitizer pump, or an incorrect dosage setting. At this point, it is recommended to contact a qualified service technician to inspect the pump, lines, and system settings.
