Manitowoc ice makers are known for their reliability, performance, and long-lasting build. But like any commercial appliance, even the best machines eventually show signs of wear. If your Manitowoc unit isn’t making ice like it used to, is making strange noises, or starts leaking, chances are that some components are worn out.
Catching these problems early can help you avoid costly repairs, unexpected breakdowns, or equipment downtime. Here’s how to spot and troubleshoot worn-out parts in your Manitowoc ice machine.

Common Signs of Worn-Out Parts
1. Reduced Ice Production
If the machine is producing less ice than usual or if freezing cycles are taking too long, the issue may involve:
- A faulty water inlet valve that isn’t supplying enough water
- Scale buildup on the evaporator plate
- A worn-out compressor or low refrigerant levels
2. Unusual Noises
Grinding, buzzing, or rattling sounds can indicate:
- Worn fan motors or bearings
- Loose screws or mounting brackets
- A failing compressor that’s struggling to maintain pressure
3. Ice Quality Issues
Soft, cloudy, or misshapen ice cubes may be due to:
- A worn or clogged water filtration system
- Mineral buildup in the water lines or distribution system
- A dirty or corroded evaporator plate
4. Water Leaks
If water is leaking from the back or bottom of the machine, check for:
- A cracked or disconnected drain hose
- A failing water pump
- Loose inlet fittings or a leaky valve
5. Error Codes
Many Manitowoc models display error codes when there’s a malfunction. These codes are your first clue:
- Refer to the user manual or manufacturer’s website for code meanings
- Repeated or persistent errors usually point to failing electrical components such as sensors, thermostats, or control boards
How to Check and Replace Worn Parts
1. Unplug the Machine
Always disconnect power before opening or inspecting any part of the unit.
2. Perform a Visual Inspection
Look for signs of wear, such as:
- Cracks or corrosion
- Loose or frayed wires
- Mineral buildup on key components
Key parts to examine include:
- Water inlet valve
- Evaporator plate
- Circulation pump
- Fan motor and blades
- Thermistors and sensors
3. Run a Diagnostic Cycle
Many Manitowoc machines include built-in diagnostic features. Use them to help identify which component may be failing.
4. Use Genuine Replacement Parts
Always replace worn components with original Manitowoc parts (OEM) to maintain safety, performance, and warranty coverage.
