Hobart dishwasher not filling water
Issues with water filling require careful examination. Here’s how to fix commercial dishwasher:
- Low water pressure: Insufficient water pressure can impede proper filling. Check for a clogged hose strainer and ensure that the facility's water pressure meets the machine's requirements. If the main water supply valves are not working, they may need replacement.

- Leaking fill solenoid valve: Check for leaks in the fill solenoid valve, which could lead to overfilling. If water continues to flow when the dishwasher is powered off, seek assistance from an authorized technician.
- Unleveled machine: A dishwasher that isn't level might overfill. Have the unit leveled by a professional to ensure proper operation.
- Associated Hobart dishwasher error codes: “E0,” “E2,” “E3,” “E4” on LX18 and LX30 models; “DR1 PRBLM,” “FILL1 PRBLM,” FILL2 PRBLM” or FILL3 PRBLM” on LX40 models

Dishes aren't clean or spotting appears on silverware and glasses
Dirty or spotted dishes may result from various issues:
- Obstructed wash arms: Dirty or obstructed wash arms can result in inadequate cleaning. Remove any blockages and clean the wash arms according to the manual's instructions.
- Clogged strainers: Blocked strainers can limit water supply to the pump, affecting cleaning performance. Unclog the strainers following the cleaning instructions in the owner's manual.
- Low water temperature: Ensure that the dishwasher maintains a water temperature above 120°F for chemical sanitizing models and 150°F for other models. Low water temperatures can impact the effectiveness of the cleaning process.
- Improper rack loading: Improperly loaded racks can leave dishes, glasses, and silverware dirty. Refer to the owner's manual for proper loading instructions.
- Low water pressure or insufficient filling: Check for a clogged hose strainer and ensure that the facility's water pressure meets the dishwasher's requirements. In some models, adjusting the cycle timer may be necessary.
- Hard water: Install a water softener or use a rinse agent if the facility's water is hard. Hard water can hinder cleaning performance and prevent the dishwasher from filling correctly.
- Detergent dispenser issues: A clogged detergent dispenser can lead to ineffective cleaning. Clean the dispenser according to the instructions in the dishwasher's manual.
Dishes and other objects damaged
Different types of damage require specific considerations:
- Etching: Etching can result from a combination of high water temperatures, soft water, high-alkaline cleaning solutions, or soft glass.
- Chipping: Incorrectly loading the dishwasher can cause items to come in contact with each other, leading to chips and cracks.
- Tarnishing: Avoid washing silver and pewter dishes in dishwashers that use chemical sanitizers.
- Pitting: Stainless steel can pit when in contact with certain foods like vinegar, salt, and fruit juice.
- Marks and Staining: Black and gray marks could come from items being rubbed with aluminum, while brown and dark stains could result from high iron in the water.
- Ware and Rusting: Certain plastic and wooden items may wear out from high temperatures. Check if they are dishwasher safe. Rusting on cast-iron items may also occur if they are not dishwasher safe.
Readings of low temperatures
For correct water temperature, examine potential causes:
Rapid cycle use: When the incoming water temperature is low and the cycle use rate is high, it may lead to inadequate cleaning. Adjust the machine's settings accordingly.
Low temperature from supply: Ensure that the dishwasher's water temperature is above 120°F for chemical sanitizing models and 150°F for other models. Adjust the settings if necessary.
Heavy ware loads: Overloaded racks can cause the wash water to cool down, affecting cleaning performance. Follow the loading instructions in the owner's manual.
Inadequate chemical feeding
Here are some reasons why chemicals might not be feeding into your machine:
- Kinked tubes: Check for smooth bends and unkink any tangled tubing that feeds chemicals into the dishwasher.
- Air leaks: Inspect feeder hose connections for air leaks. Tighten connections to resolve this issue.
- Low chemicals: Ensure an adequate supply of chemicals in the dishwasher for proper cleaning. Regularly check and replenish chemical levels as needed.
