  If your MVP Ice Maker displays error code E5, it could be due to several reasons. First, ensure that the water supply is turned on and properly connected. Also, check if the water pressure is within the range of 0.2psi to 0.8psi. Other potential issues include a faulty water inlet valve, a leak in the water tank, a malfunctioning water pump, or a leak in the water drain valve. Check and replace these components if needed.

What to do if my MVP Ice Maker displays error E1?

  Kevin VasquezAug 15, 2025
  If your MVP Ice Maker shows error code E1, it may be due to a few reasons. It could be caused by ice damper dislocation, in which case you should check the ice damper and ice full sensor, and replace them if necessary. It may also be due to high ambient temperature, so wait until the ambient temperature meets the requirement. Poor ventilation can also cause this error, so make sure there is sufficient clearance for proper air circulation. Other possible causes include a shortage of refrigerant or an inefficient compressor (check for leaks and recharge refrigerant, replace the compressor if needed), or a shortage of water (check or replace water system components of the ice machine and water supply).

  Scott LunaAug 20, 2025
  If your MVP Ice Maker is showing error code E4, the ambient temperature might be too high; wait until it meets the requirement. Poor ventilation could also be the cause, so ensure sufficient clearance for air circulation. Another possibility is a dirty condenser, which you should clean. Finally, the condenser fan might be faulty, so check it and replace it if necessary.

What causes error E6 on an MVP Ice Maker?
- S
  Sherri RossAug 26, 2025
  If your MVP Ice Maker displays error code E6, it could be due to a few reasons. The condenser temperature might be too high, so ensure sufficient clearance for proper air circulation and check the pressure of the refrigeration system. There could also be a blockage in the cooling system, so check the condenser and clean it. Finally, the pressure switch might be faulty, so check it and replace it if necessary.

What does error E3 mean on my MVP OSION OCM-350?

  If your MVP Ice Maker is displaying error code E3, it could be due to the solenoid valve not opening; check and replace the valve if necessary. It may also be caused by the ice-making time being set too short, resulting in ice that is too thin; make sure the set time of the ice-making cycle complies with the manufacturer's suggested time range. Another potential cause is insufficient water or a lack of water in the water tank; refer to the remedies for water shortage.

What does error E9 mean on MVP Ice Maker?
- B
  Bradley BrooksSep 5, 2025
  If your MVP Ice Maker displays error code E9, it could be due to a defective water temperature sensor. Check the water temperature sensor and replace it if necessary. Another potential cause is a loose or disconnected connector.

This document is a user installation and maintenance manual for Commercial Ice Makers, specifically the OSION Modular Models OCM-350, OCM-500, and OCM-1000, manufactured by MVP Group.

The primary function of these devices is to produce ice. They are designed for indoor use and feature touch controls for operation, with an easy-to-read digital display and indicators showing the machine's status.

Important Technical Specifications:

Models: OCM-350, OCM-500, OCM-1000
Refrigerant: R-290 (flammable, requiring specific handling and disposal)
Electrical Ratings (for OCM-350 and OCM-500):
- OCM-350: 115V, 60Hz, 800W, 9.5A
- OCM-500: 115V, 60Hz, 940W, 10A
- The manual emphasizes connecting to an independent power source with specified voltage and frequency, noting that voltage fluctuations should not exceed +10% or -5% of the rated voltage.
Water Supply Pressure: 0.2psi to 0.8psi (a pressure reducing valve is required if pressure exceeds 0.8psi).
Water Inlet Temperature: 40°F to 77°F (5°C to 25°C).
Ambient Air Temperature for Operation: 40°F to 104°F (5°C to 40°C).
Minimum Clearance: 15mm around the ice maker for proper ventilation.
Water Inlet Pipe Diameter: Internal 3/4" connector.
Drain Pipe Diameter: Internal 3/4" connector.

Usage Features:

Touch Control Panel: Allows users to operate the ice machine by lightly tapping control buttons.
Digital Display and Indicators: Provides real-time status updates including:
- Ice making cycle time (minutes)
- Water clean time (minutes)
- Countdown time until ice maker starts (hours)
- Error codes
- Standby mode
- Indicators for Start & Standby, Set, Water clean, Ice making, Ice harvest, Ice bin full, Error code, Water less, Up, and Down.
Ice Production: Initiated by tapping the start/standby button for 3 seconds. The button illuminates green, and the ice making indicator turns green. The display shows the ice making time. The machine automatically executes ice making cycles after plugging in and powering up.
Water Inlet Filling: Display shows "Co" during water inlet filling.
Immediate Harvest: During an ice making cycle, pressing the set button for 5 seconds initiates an immediate harvest cycle.
Ice Harvest: After ice production, the machine switches to harvest mode, indicated by a blue ice harvest light. The water pump stops, and the hot gas bypass valve energizes to release ice.
Standby Mode: Tapping the start/standby button stops ice production, displaying "Off" and a flashing lamp.
Ice Full Detection: The ice maker automatically stops production when the ice bin is full. The ice full indicator lamp illuminates yellow, the button illuminates green, and "FL" is displayed.
Water Clean Cycle: Initiated by tapping the clean button for 3 seconds. The clean indicator illuminates white, and "CN" is displayed. The machine rinses itself for about 5 minutes when first started.
Delay to Resume Ice Production: Users can set a delay of 0-24 hours for ice production. This feature helps manage ice production and reduce costs. The set button illuminates white, and the start/standby button flashes, displaying the countdown time. Selecting "00" disables the delay.
Ice Making Cycle Time Adjustment: The up/down buttons allow adjustment of the ice making cycle time between 0 and 45 minutes, with a default of 16 minutes for maximum production. Recommended cycle lengths vary based on ambient air temperature (e.g., 8-12 minutes for <10°C, 20-30 minutes for 35-42°C).
Auto-Lock Feature: The ice machine auto-locks if there's no tap or operation for 30 seconds. To unlock, tap the "power" key for 3 seconds.
Compressor Protection: A minimum 3-minute wait is required before restarting the ice maker after turning it off to prevent compressor damage.

Maintenance Features:

Exterior Cleaning: Clean the stainless steel surface with a micro-fiber cloth or sponge, following the grain of the steel. Avoid abrasive or metallic products, alcohol, or disinfectants on plastic components.
Air Filter Cleaning: The condenser dust filter should be cleaned every 15 days using a soft brush and vacuum cleaner. The rear panel can be lifted out by pushing down a buckle to access the filter.
Condenser Cleaning: Recommended every six months by a qualified technician. Disconnect power, remove the rear panel, and clean dirt and dust from the condenser with a soft brush and vacuum cleaner.
Water Distributor, Water Tank, and Float Switch Cleaning: These parts should be cleaned routinely (every three months with a citric acid soda power solution) to remove mineral, dirt, and lime scale buildup. The manual also recommends using the machine's water clean program every three days.
Troubleshooting Guide: The manual includes a comprehensive troubleshooting section with error codes, symptoms, possible causes, and recommended solutions for common issues like ice damper/full sensor faults, poor cooling, ice harvest overtime, ambient temperature issues, water supply problems, pressure limit issues, and condenser/water temperature sensor faults.

Safety Information:

The manual includes "DANGER" and "WARNING" symbols to highlight potential hazards.
It explicitly states that installation, repairs, or maintenance must be performed by certified and properly trained technicians.
At least three persons or a lifting device are recommended for moving the ice machine.
