E79 Flowmeter Error: What It Means & How to Fix It
The E79 Flowmeter Error on a Franke coffee machine occurs when the flowmeter detects a disruption in water flow during brewing. This issue can prevent your machine from dispensing coffee correctly. Before calling a technician, try these troubleshooting steps to resolve the problem.
Common Causes of the E79 Flowmeter Error
The E79 error can be triggered by several issues:
- Blocked or dirty brewing unit – Coffee oils and debris can clog the system.
- Coffee oil buildup in the coffee lines – Over time, coffee residue can obstruct water flow.
- Blocked or faulty coffee valve – A stuck valve can prevent water from circulating properly.
- Faulty flowmeter – If the sensor malfunctions, it may incorrectly detect a lack of water flow.
- Water supply issues – If you also see an E87: Initialising Water Line error, check your water supply.
How to Fix the Franke Coffee Machine E79 Flowmeter Error
Before requesting a service call, try these simple troubleshooting steps:
Step 1: Remove and clean the brewing unit
The brewing unit requires regular cleaning to prevent blockages.
- Remove the brewing unit from the machine.
- Wash it thoroughly with hot water and a scrubbing brush.
- Pay extra attention to the metal shower screens—they should be smooth to the touch.
- Reinstall the brewing unit and restart the machine.

Step 2: Perform a Double Tablet Clean Cycle
The automatic cleaning cycle in your Franke machine uses cleaning tablets to break down coffee oil buildup.
- Start the clean cycle as usual.
- When prompted to insert the cleaning tablet, insert TWO tablets instead of one.
- Complete the cleaning cycle.
Why this works: Double cleaning tablets provide deeper cleaning, helping remove stubborn blockages in the system.
