TLDR
On your HOBART LXe SERIES DISHWASHERS unit, if chemicals are not feeding, it typically points to issues with the chemical supply system. This could be due to low chemical levels, air leaks at feeder hose connections, or kinked dispenser tubes preventing flow. Promptly addressing these issues is crucial for effective dishwashing.
Technical Details
Repair Steps:
- Check Chemical Levels: Verify that your chemical containers (detergent, rinse aid, sanitizer) are not empty. Replace or refill as necessary, ensuring the pickup tubes are fully submerged.
- Inspect Feeder Hose Connections: Carefully examine all feeder hose connections for air leaks. Pay close attention to the insertion of quick-connect fittings and the security of wire ties at tube-to-tube connections. Re-seat or tighten any loose connections.
- Examine Dispenser Tubes for Kinks: Trace the path of all chemical dispenser tubes from the chemical containers to the dishwasher. Look for any bends, twists, or obstructions that could be kinking the tubes and restricting chemical flow. Straighten any kinks to ensure smooth passage.
- Purge Air from Lines (if applicable): If chemicals ran out, it’s possible air has entered the lines. Consult your LXe user manual for instructions on how to prime or purge air from the chemical feed system, if this feature is available.
- Verify Pump Operation: While performing the above checks, listen for the chemical dispenser pumps operating during a wash cycle. If you don’t hear them, or if the problem persists after verifying chemical supply and connections, the pump itself might be faulty and require professional service.
Common Questions:
Q: What types of chemicals are used in a HOBART LXe SERIES DISHWASHERS?
A: HOBART LXe series dishwashers typically use commercial-grade detergent, rinse aid, and sometimes a sanitizer, depending on local health codes and machine configuration. Always use chemicals specifically formulated for commercial dishwashers.
Q: How often should I check my chemical levels?
A: It’s best practice to check chemical levels daily, or at the start of each shift, especially in high-volume operations. This preventive measure helps avoid unexpected interruptions in washing performance.
Q: Can I use generic chemicals in my HOBART LXe dishwasher?
A: While generic chemicals might seem cost-effective, using products not approved or formulated for your HOBART LXe can lead to poor wash results, potential damage to internal components, and may void your warranty. Always refer to Hobart’s recommendations for chemical compatibility.
