Overview of Top Legacy Models
Among Hobart’s long-standing models, the LXi Series stands out as a compact and dependable undercounter dishwasher. Designed for smaller commercial kitchens, it delivers consistent performance but can occasionally display fill and drain-related error codes such as E0 through E6.
The AM Select Series is another workhorse, typically installed in mid-volume operations. This model is known for its versatility and robust design but may present issues with its temperature probes or float switch if not maintained properly.
For high-volume dishwashing needs, the CL and CLe Series conveyor dishwashers are industry staples. With increased capacity and automation, these machines are prone to issues like conveyor jams, water-level discrepancies, and final rinse temperature faults, especially under heavy use.

Review of Top New Models
Recent years have seen Hobart refining its designs to incorporate smart features and enhanced diagnostics. The Hobart AM16 Series exemplifies this advancement. This modern, ventless model reduces energy consumption while streamlining the cleaning process. Common alerts include low rinse temperature warnings and door switch issues — all monitored with greater accuracy through built-in sensors.
Similarly, the LXe Series improves upon the LXi’s foundation with better temperature controls, intuitive display codes, and quieter operation. It’s ideal for establishments where space is tight but standards remain high.
Lastly, the CL44EN Series stands out in Hobart’s modern conveyor line. This model features energy-saving technology and clearer on-screen diagnostics that speed up troubleshooting and minimize downtime.

Common Errors and How to Troubleshoot
When your Hobart dishwasher shows an error code, it’s signaling a specific mechanical or operational issue.
| Model | Error Code | Meaning | Troubleshooting Tips |
| LXi/AM Select | E0, E2, E3, E4 | Not filling properly | Check water valve, clean strainer, ensure float switches move freely |
| LXi/AM Select | E5 | Not draining | Check drain line, restart machine, check for kinks or clogs |
| LXe | Door Open | Door ajar | Ensure doors are fully closed |
| LXe | Wash Arm Alert | Arm obstructed | Remove and clean any blockages |
| LXe | Low Rinse Temp | Rinse temp too low | Check water temp and heater unit; contact service if persistent |
| CL/CLe | Clear Conveyor Jam | Conveyor jam | Remove rack, restart machine |
| CL/CLe | Delime Recommended | Lime buildup | Run delime cycle with appropriate cleaner |
| CL/CLe | Water Change Required | Dirty water detected | Drain and refill tanks; check drain pump function |
The following is a summary of the most common errors across models and how to address them:
On the LXi and AM Select Series, error codes such as E0, E2, E3, and E4 usually indicate a failure to fill properly. These can often be resolved by checking the water inlet valve, cleaning the strainer, or ensuring that the fill float switch moves freely.
An E5 code signals drainage issues, which may involve checking for kinks in the drain line or restarting the machine. Codes like P1 through P3 relate to temperature sensor malfunctions and usually require professional service.
The LXe models provide clearer guidance with codes like “Door Open”, “WASH ARM ALERT”, or “LOW RINSE TEMP”. These often stem from user oversight or routine maintenance issues — for example, forgetting to fully close the door or a clogged spray arm. However, repeated low temperature warnings such as “LOW RINSE TEMP / Check Water Input” may suggest deeper problems with the incoming water supply or heating element.
In CL and CLe Series conveyor models, common issues include “Clear Conveyor Jam”, “Delime Recommended”, and “Reset Required”. A jam can be resolved by removing the dish rack and restarting the machine, while lime scale buildup demands descaling with appropriate dishwasher-safe cleaning agents.
If the “Water Change Required” message appears, drain the tanks and allow the machine to refill, verifying that the drain pump is operating properly.
