- Prepare the Dishwasher:
- Disconnect the dishwasher from the electrical outlet or turn off the circuit breaker.
- Turn off the water supply valve to the dishwasher.

- Disconnect the Old Valve:
- Place a towel or small pan underneath the valve to catch any residual water.
- Disconnect the water supply line from the valve using a wrench.
- Disconnect the electrical connector(s) from the valve. Note their positions if multiple connectors exist.
- Disconnect the water outlet hose (to the dishwasher tub) from the valve.
- Remove any mounting screws or clips securing the valve to the dishwasher frame.
- Install the New Valve:
- Position the new UpStart Components water inlet valve in the same location as the old one.
- Secure the valve with the mounting screws or clips.
- Connect the water outlet hose to the new valve. Ensure it is securely clamped.
- Connect the electrical connector(s) to the new valve.
- Connect the main water supply line to the new valve. Hand-tighten first, then use a wrench for a snug fit, but do not overtighten.

- Test and Finalize:
- Slowly turn on the water supply valve and check for any leaks around the new valve connections. Tighten if necessary.
- Carefully slide the dishwasher back into its cabinet.
- Reconnect the dishwasher to the electrical outlet or turn on the circuit breaker.
- Run a short wash cycle to confirm proper operation and check for leaks again.
5. Operating Principles
The water inlet valve is an electrically operated solenoid valve. When the dishwasher's control board signals for water, the solenoid energizes, opening the valve and allowing water to flow into the dishwasher tub. Once the required water level is reached, the control board de-energizes the solenoid, closing the valve and stopping the water flow.
Proper operation of this valve is critical for the dishwasher to fill correctly and prevent overfilling or underfilling.
6. Maintenance
The UpStart Components water inlet valve is designed for durability and typically requires no routine maintenance. However, to ensure its longevity and the overall health of your dishwasher:
- Periodically check the water supply line and connections for any signs of leaks or corrosion.
- Ensure your home's water pressure is within the recommended range for dishwashers.
- If your home has hard water, consider installing a water softener to prevent mineral buildup that could affect the valve over time.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Dishwasher not filling with water. | Water supply turned off; kinked water line; faulty water inlet valve; clogged filter screen in valve. | Ensure water supply is on. Check water line for kinks. Inspect the valve's filter screen for debris and clean if necessary. If valve is faulty, replacement is required. |
| Dishwasher overfilling or continuously filling. | Faulty water inlet valve (stuck open); faulty float switch. | If the valve is stuck open, it needs replacement. Check the float switch for proper operation and ensure it's not obstructed. |
| Water leak around the valve. | Loose connections; damaged water line; cracked valve housing. | Tighten all connections. Inspect water lines for damage and replace if necessary. If valve housing is cracked, replace the valve. |
If troubleshooting steps do not resolve the issue, professional assistance may be required.
