Introduction
This manual provides essential information for the safe and effective handling, installation, and maintenance of the HOBART 883658-1 Dishwasher Water Inlet Solenoid Valve. This component is crucial for regulating the flow of water into your dishwasher during its operational cycles. Please read these instructions carefully before proceeding with any installation or maintenance.
Safety Information
- Always disconnect power to the dishwasher before attempting any installation or maintenance.
- Turn off the water supply to the dishwasher before disconnecting any water lines.
- Wear appropriate personal protective equipment (PPE), such as gloves and eye protection.
- If you are unsure about any step, consult a qualified technician.
Product Overview
The HOBART 883658-1 is a water inlet solenoid valve designed for specific HOBART dishwasher models. It controls the flow of water into the dishwasher tub based on electrical signals from the dishwasher's control board. This ensures the correct amount of water is supplied for each wash cycle.
Installation
This section outlines the general steps for replacing a water inlet solenoid valve. Specific procedures may vary depending on your dishwasher model. Always refer to your dishwasher's service manual for detailed instructions.
- Preparation: Disconnect the dishwasher from the electrical power supply and turn off the water supply valve.
- Access the Valve: Depending on your dishwasher model, you may need to pull the dishwasher out from its cabinet, remove the lower access panel, or access it from the rear.
- Drain Water: Place a shallow pan or towels under the valve to catch any residual water when disconnecting the water lines.
- Disconnect Water Lines: Carefully disconnect the water inlet hose from the valve and any internal water lines connected to the valve.
- Disconnect Electrical Connections: Unplug the electrical connector(s) from the solenoid valve. Note the orientation if there are multiple wires.
- Remove Old Valve: Unscrew or unclip the old solenoid valve from its mounting bracket.
- Install New Valve: Mount the new HOBART 883658-1 solenoid valve in the same position as the old one. Ensure it is securely fastened.
- Reconnect Electrical Connections: Connect the electrical connector(s) to the new valve.
- Reconnect Water Lines: Attach the water inlet hose and any internal water lines to the new valve. Ensure all connections are tight to prevent leaks. Use new hose washers if necessary.
- Test for Leaks: Slowly turn on the water supply and check for any leaks around the valve connections. Tighten as needed.
- Restore Power and Test: Restore electrical power to the dishwasher. Run a short cycle to confirm proper operation and check for any further leaks or issues.
Operation
The water inlet solenoid valve operates automatically as part of the dishwasher's wash cycle. When the dishwasher's control board signals for water, the solenoid energizes, opening the valve to allow water to flow into the tub. Once the required water level is reached, the solenoid de-energizes, closing the valve and stopping the water flow.
The flow control mechanism ensures that water enters the dishwasher at a regulated rate, specified as 51 liters per minute (51/MIN) for this model, contributing to efficient and consistent wash performance.
Maintenance
As a sealed component, the solenoid valve itself requires no routine user maintenance. However, proper care of your dishwasher can extend the life of all its components, including the water inlet valve.
- Water Quality: Hard water can lead to mineral buildup (scale) which may affect the valve's performance over time. Consider using a water softener if you have hard water.
- Inlet Screen: Many water inlet valves have a small screen filter at the water inlet connection to prevent debris from entering the valve. Periodically check and clean this screen if water flow issues arise. (Ensure water and power are off before checking).
- Leak Checks: Regularly inspect the area around the water inlet valve and hoses for any signs of leaks. Address any leaks promptly to prevent water damage.
Troubleshooting
If your dishwasher is experiencing water-related issues, the water inlet solenoid valve could be a contributing factor. Here are some common symptoms and potential causes:
| Symptom | Possible Cause (Solenoid Valve Related) | Action |
|---|---|---|
| Dishwasher not filling with water | Solenoid valve is faulty (not opening), or inlet screen is clogged. | Check water supply. Inspect/clean inlet screen. Test solenoid for continuity (requires multimeter and technical knowledge). |
| Dishwasher filling slowly | Partially clogged inlet screen or partially faulty solenoid valve. | Inspect/clean inlet screen. |
| Dishwasher continuously fills with water (overflows) | Solenoid valve is faulty (stuck open). | Immediately turn off water supply and power. Replace valve. |
| Water leaks around the valve | Loose connections, cracked valve housing, or worn seals. | Tighten connections. Inspect valve for damage. Replace valve if cracked or seals are compromised. |
For complex issues or if you are uncomfortable performing these checks, it is recommended to contact a professional appliance repair technician.
