What Flow Meter Error means on your Dacor coffee machine (dacor coffee machine flow meter)
Dacor coffee machine flow meter error means the flow meter, the component that measures how much water is actually moving through the machine, is reporting that no water reached it during a fill attempt. Depending on which CM24 variant is installed, the manual attributes this to two different causes: on the CM24T-1 tank version it means there is no water in the tank, and on the CM24P-1 plumbed version it means the dedicated water supply is not connected or has been shut off. Distinguishing which version is installed is the first and most useful step, since the fix is different for each.
Symptoms
Read these against your coffee machine: they are what tells Flow Meter Error apart from the other things that can go wrong on a Dacor coffee machine.
- The display shows “Flow Meter Error” and buttons are disabled until it clears.
- On the tank version, the reservoir may be visibly empty or nearly so when the error appears.
- On the plumbed version, the shutoff valve behind the machine may be found closed.
- No water sound is heard during an attempted fill just before the error appears.
- The error can recur immediately on the next brewing attempt if the underlying water source issue is not addressed.
Common causes
Each cause below can produce Flow Meter Error on a coffee machine, and only measurement on the coffee machine itself will tell you which one you actually have.
- Empty water reservoir — on the CM24T-1 tank version, an empty or low tank is the direct cause named in the manual.
- Water supply not connected or shut off — on the CM24P-1 plumbed version, this is the direct cause named in the manual.
- Failed flow meter sensor — the sensor itself is not detecting water that is genuinely flowing.
- Clogged inlet filter — sediment restricting the water path can reduce flow enough to read as no flow at all.
- Air trapped in the line — after a reservoir refill or new installation, trapped air can temporarily prevent normal flow detection.
Troubleshooting steps you can try
Work through these checks on your coffee machine in order before calling anyone out, and stop wherever mains voltage, gas, a hot surface or a sealed component on the coffee machine is involved.
- On the tank version, refill the water reservoir completely and confirm it is seated correctly in its holder.
- On the plumbed version, check that the dedicated shutoff valve behind the machine is fully open.
- Run a water-only priming cycle if the manual describes one, to help clear any trapped air in the line.
- Check any visible inlet filter for buildup and clean or replace it per the manual’s guidance.
- Attempt a fresh brew only after confirming water supply is adequate for the specific variant installed.
Parts a technician may replace
On a coffee machine in this condition the likely candidates are the flow meter sensor, water reservoir (cm24t-1), water supply connection (cm24p-1), and fill valve. Each is tested on the coffee machine before it is replaced, and the part is matched to your coffee machine from its model and serial number.
When to call a technician
If water supply is confirmed adequate for the installed variant and the flow meter error persists, the sensor itself needs testing, which is technician work. This rates Medium on a coffee machine, so take your time — but do not keep clearing Flow Meter Error on the coffee machine without finding out why. We hold no affiliation with the manufacturer of your coffee machine; the parts are genuine and the labor is warranted for 30 days.
