3U0111-03 Water Inlet Solenoid Valve – 120V, 60Hz | J248-033

3U0111-03 Water Inlet Solenoid Valve – 120V, 60Hz | J248-033

The 3U0111-03 Water Inlet Solenoid Valve is an electrically operated water-control component designed for compatible commercial ice machines. It regulates the incoming water supply during the machine's operating and ice-making cycles.

When the valve receives a 120V electrical signal, its solenoid activates and opens the water passage, allowing the required water to enter the machine. When electrical power to the solenoid is removed, the valve closes to stop the incoming water supply.

Proper operation of the inlet valve is important for maintaining the correct water level and consistent ice production. A worn, blocked or electrically failed valve can contribute to problems such as insufficient water filling, continuous filling, leakage or inconsistent machine performance.

The 3U0111-03 is also identified by the valve/vendor reference J248-033 in manufacturer technical documentation.

Main Features:

• 💧 Automatic Water Inlet Control – Controls water entering the ice machine during operating cycles.
• ⚡ 120V Operation – Designed for compatible 120V equipment.
• 🔌 60Hz Frequency – Confirmed electrical frequency for this valve configuration.
• ❄️ Commercial Ice Machine Application – Designed for water-control applications in compatible ice-making equipment.
• 🔄 Automatic Open/Close Operation – Solenoid-actuated design controls water flow according to the machine's control signal.
• 🎯 Controlled Water Filling – Helps maintain the required water supply for proper ice-making operation.
• 🛠️ Replacement Component – Suitable for replacing a worn, blocked, leaking or electrically failed compatible inlet valve.
• 🔎 J248-033 Reference – Manufacturer technical documentation identifies 3U0111-03 with vendor number J248-033.
• 🧊 Reliable Ice-Making Support – Proper water regulation supports consistent machine operation and ice production.

Main Specifications:

The current manufacturer technical guide associates 3U0111-03 / J248-033 with diaphragm 4A3362-01 and identifies SP9200010 as the replacement screen for the CKD valves.

How It Works?

The 3U0111-03 functions as an electrically controlled inlet valve.

When the ice machine requires water, the control system supplies power to the solenoid coil. The energized solenoid actuates the valve mechanism, allowing water to pass through the valve and enter the machine.

Once the required filling stage is complete, power to the solenoid is removed and the valve closes, stopping water flow.

This automatic operation allows the machine to control its water supply without manual intervention.

Common Signs a Water Inlet Valve May Need Replacement

A faulty or restricted inlet valve may contribute to:

• Insufficient water entering the machine
• Slow water filling
• No water entering during the fill cycle
• Water continuing to flow when it should stop
• Leakage around the valve
• Irregular water levels
• Reduced or inconsistent ice production
• Solenoid failing to activate
• Unusual noise during valve operation

Other water-supply and electrical components can produce similar symptoms, so proper troubleshooting is recommended before replacing the valve.

Compatible Equipment

Manufacturer technical documentation identifies 3U0111-03 / J248-033 for several commercial ice-machine families, including:

KM Series

• KM-500 series

KMD Series

• KMD-300M series
• KMD-450M series

KML Series

• KML-600M series

KMS Series

• KMS-830M series

The current manufacturer technical guide lists these families against 3U0111-03 / J248-033. Older technical documentation also lists applications including KM-450/452/500 and KML-600, indicating that compatibility can vary by machine generation.

Third-party parts references show additional individual compatible configurations, including KM-515, KM-520, KM-650, KM-660, KMD-460, KMD-530, KML-631 and KML-700 variants.

Important: Always verify the machine model, serial number and existing valve part number before ordering, because similar-looking water valves can have different flow characteristics. Manufacturer documentation specifically warns that using the correct valve is important because water-valve flow rates differ.

Main Benefits:

• Accurate Water Control: Helps supply the required amount of water during the machine's operating cycle.
• Automatic Operation: Electrical solenoid actuation enables water flow to be controlled directly by the equipment.
• Supports Consistent Ice Production: Correct inlet-water operation helps maintain the water conditions required for normal ice production.
• Direct Part Identification: The 3U0111-03 / J248-033 identification makes it easier to verify the correct replacement component.
• Serviceable Design: Manufacturer documentation identifies replacement screen and diaphragm components for servicing the valve.

Installation & Replacement Note

Before replacing the existing valve with 3U0111-03, verify:

• Existing valve part number.
• 120V electrical requirement.
• 60Hz frequency.
• J248-033 valve identification.
• Water inlet/outlet configuration.
• Machine model and serial number.
• Water pressure and supply condition.
• Wiring and electrical connections.
