Commercial dishwashers like the Hobart models are vital in keeping kitchen operations smooth. However, they can occasionally face some operational issues.

Understanding Hobart Dishwasher Error Codes and Solutions

Trouble with Starting the Dishwasher

• Machine Not Powering On: Check if the dishwasher is switched on. Inspect the power cord for any disconnections or damage. Alternatively, a tripped circuit breaker might be the cause, so try resetting it. If the "DOOR OPEN" or "dr" "op" error displays, ensure the door is securely closed.
  • Associated Error Code: “DOOR OPEN” or “dr” “op”

Filling Issues Caused:

• Inadequate Water Supply: Verify the water pressure and check if the hose strainer is clogged. Ensure the main water supply valves are functional.
• Cleaning Required: Regular cleaning, especially of the probes, can prevent filling issues.
• Drain Valve Problems: If the unit is not filling correctly, try restarting the dishwasher to clear any obstructions in the drain valve. Monitor the water level after restarting.
• Leaking or Overfilling: Inspect the fill solenoid valve for leaks, and ensure the dishwasher is properly leveled to prevent overfilling.
  • Associated Error Codes: “E0,” “E2,” “E3,” “E4” on LX18 and LX30 models; “DR1 PRBLM,” “FILL1 PRBLM,” “FILL2 PRBLM,” “FILL3 PRBLM” on LX40 models

Drainage Reason Caused:

• Machine Not Draining: Check for blockages in the drain pipes. If none are found, a power cycle might help. If issues persist, professional assistance may be required.

Cleaning and Spotting Issues Caused:

• Unclean Dishes and Spotting: Ensure wash and rinse arms are not obstructed or dirty. Clean the strainers regularly. Verify the water temperature and pressure are appropriate for your model. Check if racks are loaded correctly, and use a water softener or rinse agent if dealing with hard water. Also, ensure the detergent dispenser is not clogged.

Damage's to Dishes:

• Various Types of Damage: Issues like etching, chipping, tarnishing, pitting, marks, wear, rusting, and fading patterns on dishes can arise from factors such as high water temperature, improper loading, chemical exposure, and unsuitable dishware materials.

Low Temperature Issues Caused:

• Inadequate Water Temperature: Confirm the incoming water temperature and adjust cycle use rate. Overloaded racks can lower the wash water temperature. If the issue is with the booster or sump heater, professional servicing is recommended.

Chemical Feeding Problems

• Improper Chemical Dispensing: Inspect for kinks in the tubes, air leaks at hose connections, and the chemical levels in your machine.
