Introduction to Hobart Dishwasher Drain Valve Replacement
Commercial dishwashers are the backbone of any food service operation, and Hobart machines are among the most trusted in the industry. At Malachy Parts Plus, we understand that even the most reliable equipment requires maintenance and occasional part replacements. One of the most common service needs for commercial dishwashers is drain valve replacement—a critical component that controls water discharge during operation cycles. When your Hobart dishwasher fails to drain properly, leaves standing water in the tank, or experiences leaks during operation, the drain valve is often the culprit. These issues can significantly impact your kitchen's efficiency and potentially create health code concerns if not addressed promptly. This comprehensive guide walks you through the step-by-step process of replacing a Hobart dishwasher drain valve, helping you minimize downtime and avoid costly service calls. Whether you're a maintenance technician, restaurant owner, or facilities manager, this guide provides the expertise needed to complete this repair with confidence using genuine Replacement Parts designed specifically for Hobart equipment.
Identifying Drain Valve Issues in Hobart Dishwashers
Before replacing any components, it's essential to confirm that the drain valve is indeed the source of your dishwasher problems. Misdiagnosis can lead to unnecessary parts purchases and continued operational issues.
Common Symptoms of Faulty Drain Valves
Watch for these telltale signs that indicate your Hobart dishwasher drain valve needs replacement:
| Symptom | Possible Cause | Verification Method |
|---|---|---|
| Standing water in tank | Valve not opening properly | Check for mechanical obstruction or electrical failure |
| Slow draining | Partial valve failure | Inspect valve for debris or partial opening |
| Water leaks during operation | Worn seals or cracked valve body | Visual inspection for leaks around valve assembly |
| Unusual noises during drain cycle | Damaged internal components | Listen for grinding or irregular sounds during drainage |
| Error codes on digital models | Valve operation failure detected | Check manufacturer's error code guide |
Once you've confirmed a drain valve issue, identify your specific Hobart model. Different models use different valve configurations, such as the Hobart 00-118976 BODY DRAIN VALVE for many standard commercial units, or specialized valves like the Hobart 00-074696 VALVE for certain models. Your model number is typically located on a data plate inside the door panel or on the machine's rear.

Step-by-Step Drain Valve Replacement Procedure
Follow these detailed steps to safely and effectively replace your Hobart dishwasher drain valve:
Step 1: Safety Preparations
Disconnect all power to the dishwasher by turning off the dedicated circuit breaker. Shut off the water supply valves and place towels around the work area to catch any water spillage.
Step 2: Access the Drain Valve
Remove the front kick panel or access panel of your Hobart dishwasher. Some models may require removing side panels or other components. Take photos of the original configuration to aid in reassembly.
Step 3: Drain Remaining Water
Place a shallow container beneath the drain valve to catch any remaining water in the system. Open the drain valve manually if possible to empty the tank completely.
Step 4: Disconnect Electrical Connections
For electrically operated valves, carefully disconnect the wiring harness or solenoid connections. Label wires if necessary to ensure proper reconnection later.
Step 5: Remove the Old Valve
Using the appropriate tools, disconnect plumbing connections to the valve. Typically, this involves loosening clamps or unscrewing fittings. Remove mounting screws or brackets holding the valve in place, then carefully extract the old valve assembly.
Step 6: Install the New Valve
Position your new Hobart 00-118976 BODY DRAIN VALVE or appropriate replacement part in the same orientation as the original. Secure it with the mounting hardware, ensuring it's firmly attached but not overtightened.
Step 7: Reconnect Plumbing
Apply Teflon tape to threaded connections if applicable. Reconnect all plumbing lines to the new valve, ensuring clamps and fittings are secure but not overtightened to prevent damage.
Step 8: Restore Electrical Connections
Reconnect any electrical wiring to the valve solenoid or control mechanism according to your earlier documentation or labeling. Ensure connections are secure and properly insulated.
Step 9: Test for Leaks
Before fully reassembling the dishwasher, restore water supply and check for leaks around the valve connections. Address any leaks by tightening connections or replacing seals as needed.
Step 10: Final Testing
Restore power and run a complete wash cycle to ensure proper valve operation during both fill and drain phases. Verify the machine drains completely and operates according to specifications.
Model-Specific Considerations for Hobart Dishwashers
Different Hobart dishwasher models may have specific requirements or configurations for their drain valves. Below we outline key variations for common commercial models:
| Hobart Model Series | Valve Type | Recommended Part | Special Considerations |
|---|---|---|---|
| AM Series | Solenoid-operated | 00-118976 BODY DRAIN VALVE | Access through bottom panel |

Troubleshooting Common Issues After Replacement
Even with careful installation, you might encounter some issues after replacing your drain valve. Here are solutions to common post-replacement problems:
Post-Replacement Troubleshooting Guide
| Issue | Possible Cause | Solution |
|---|---|---|
| Valve leaks around connections | Loose fittings or missing gasket | Tighten connections or replace seals |
| Valve doesn't open/close | Electrical connection issue | Check wiring and solenoid function |
| Partial draining only | Valve partially obstructed | Check for debris or improper valve seating |
| Unusual noise during operation | Improper valve mounting | Verify alignment and secure mounting |
| Error codes persist | Control board needs reset | Power cycle unit or reset controller |
Preventative Maintenance for Extended Valve Life
Maximize the lifespan of your new drain valve with these essential maintenance practices: 1. **Regular Inspection**: Check valve operation and connections monthly for early signs of wear or leakage. 2. **Water Quality Management**: Install and maintain water softeners in areas with hard water to prevent mineral buildup that can damage valve components. 3. **Proper Filtration**: Keep scrap screens and filters clean to prevent debris from reaching and damaging the drain valve. 4. **Scheduled Cleaning**: Perform quarterly descaling of the entire dishwasher system using manufacturer-approved chemicals to prevent lime buildup. 5. **Staff Training**: Ensure kitchen staff understand proper operation procedures to prevent valve damage from improper use.
Maintenance Tip
Keep a maintenance log for your Hobart dishwasher that includes dates of valve inspections and any issues noted. This documentation helps identify patterns that might indicate underlying problems before they cause complete valve failure.
