If your coffee machine is showing an error code, flashing lights, or a warning message, this page will help you understand what it means and what to do next.

At My Coffee Machine®, we organise error-code help in a simple, practical way — based on what you can actually see on the machine. You don’t need the manual. You don’t need to guess.

Start here, then use the bot for model-specific guidance.

An error code is the machine’s way of telling you something isn’t working as expected.

Depending on the brand and model, this may appear as:

• A numeric code (e.g. E01, 53, Error 8)
  
• A text message (e.g. “NO WATER”, “EMPTY TRAY”)
  
• Flashing or blinking lights
  
• A symbol or warning icon on the display
  

Error codes can relate to water supply, heating, sensors, grinders, milk systems, or internal safety checks.

If you can see a code or message on the screen, this is the fastest route to help.

Most error codes directly point to:

• A blocked or empty water system
  
• A temperature or heating issue
  
• A component not detected (brew unit, tray, door)
  

Enter the code exactly as shown and tell the bot your machine brand and model for a precise explanation.

Some coffee machines don’t use screens and instead communicate faults using blinking indicator lights.

Flashing lights usually indicate:

• A required user action (empty tray, refill water)
  
• A failed startup or warm-up
  
• A safety stop caused by an internal fault
  

If lights are flashing:

• Note which lights are blinking
  
• Count how many times they flash
  
• Describe the pattern to the bot

If the message disappears, doesn’t make sense, or the machine stops working without showing a clear code, you can still get help.

Unknown errors are often linked to:

• Intermittent sensor readings
  
• Scale build-up
  
• Power interruptions
  
• Components failing under load
  

Describe what happened just before the problem appeared — the bot will guide you through the most likely causes.

Across most brands, error codes usually relate to one of the following areas:

• Water system – no water, low flow, air locks, blocked filters
• Heating system – boiler not heating, overheating, temperature sensor faults
• Brew group – not detected, jammed, out of position
• Grinder – jammed, not responding, motor overload
• Milk system – cleaning required, blockage, temperature issues
• Safety checks – doors open, trays missing, internal protection triggered
  

Many issues are simple to resolve once identified correctly.

Before attempting anything advanced:

1. Note the exact code or message
   
2. Turn the machine off and on once (if safe to do so)
   
3. Check water level, doors, trays, and covers
   
4. Do not force parts or reset repeatedly
   

If the error returns, use the bot to avoid trial-and-error fixes that can make things worse.

Stop using the machine and switch it off at the mains if you notice:

• Burning smells or overheating
• Water leaking internally or underneath
• Tripping electrics
• Loud mechanical noises
  

These indicate faults that should not be ignored.

Error codes vary widely between manufacturers and even between models from the same brand.

The My Coffee Machine® bot can:

• Match your brand and model
  
• Explain the exact meaning of the code
  
• Suggest safe next steps
  
• Tell you when professional service may be required
