Rivacold Coldroom Error Codes

If faults are occurring on your Rivacold Freezer or Chiller, it is very important to discover it quickly. Error codes are a great way to find out the initial problem. Error codes are usually displayed on the controller.

Rivacold error codes:

Error code	Description/Control
E1	cold room probe temperature error
E2	End defrostin probe g error
E3	3rd probe error (condenser temperature)
3rd probe error (2nd evaporator temperature)
E4	repeated heat alarm
E5	repeated HP pressure switch alarm
E6	repeated LP pressure switch alarm
LO	low temperature alarm
HI	high temperature alarm
EE	data saving alarm
Ec	condenser cleaning alarm
Er	network alarm (**)
Ed	defrosting timeout alarm
Od	door open timeout alarm
nx	slave x alarm (on master only)
Ux	slave x not connected (on master only)
u0	master not connected (on slave only)
dx	slave x download failed(on master only)
OFF	unit in stand-by (operation disabled)
dF	defrosting in progress
dFu	defrosting not performed
uM	master unit
uSx	slave x unit
Cn	terminal/control connection interrupted

What to Do When You See a Rivacold Error Code

Before calling an engineer, there are a few steps you can safely try yourself:

1. Note the code down - Write down the exact error code displayed. If the code is flashing or alternating, note the full sequence.
2. Power cycle the unit - Switch the refrigeration unit off at the isolator, wait 60 seconds, then switch it back on. This can clear temporary sensor glitches.
3. Check the basics - Make sure the door seals properly, the condenser coils are clear of dust, and airflow around the unit is not blocked.
4. Check the temperature - Verify the setpoint has not been accidentally changed.

If the error code returns after a power cycle, or if you see codes related to high pressure, compressor failure, or refrigerant issues, do not attempt a DIY fix. These require a qualified engineer with the right tools and certifications.

When to Call a Professional

Some faults need immediate professional attention to avoid further damage or safety risks:

• Refrigerant-related codes - Any error pointing to pressure problems or gas leaks must be handled by an F-Gas certified engineer. Under UK law, only qualified personnel can handle refrigerants.
• Electrical faults - PCB errors, overcurrent warnings, or voltage issues can be dangerous. Switch the unit off at the isolator and call a qualified technician.
• Repeated alarms - If the same error code keeps coming back after a reset, there is an underlying issue that needs proper diagnosis.
• Food safety concerns - If your unit stores perishable goods and the temperature has risen above safe levels, you may need to assess stock safety. The Food Standards Agency recommends keeping chilled food below 8°C and frozen food at -18°C or below.

UK Regulations for Commercial Refrigeration Maintenance

If you operate commercial refrigeration in the UK, you should be aware of these key regulations:

• F-Gas Regulation - Equipment containing fluorinated greenhouse gases must be regularly inspected for leaks. Systems with 5 tonnes CO2 equivalent or more require leak checks at set intervals. See the UK Government F-Gas guidance for full details.
• Food Hygiene Regulations 2006 - Businesses storing food must maintain correct temperatures and keep records. The Food Standards Agency temperature control guidance covers the legal requirements.
• HACCP Compliance - Your Hazard Analysis and Critical Control Points plan should include refrigeration monitoring. Temperature logs and alarm response procedures are key parts of any HACCP system.

Regular maintenance is not just good practice, it is a legal requirement for many businesses. At Be Cool Refrigeration, all our engineers are F-Gas certified and can help you stay compliant.
