What Error – Coffee Temperature / Error – Steam Temperature means on your Dacor coffee machine (dacor coffee machine temperature error)
Dacor coffee machine temperature error covers two related messages the manual documents together: “Error – Coffee Temperature,” which flags the circuit heating water for brewing, and “Error – Steam Temperature,” which flags the separate circuit heating water for milk steaming, since the CM24P-1/CM24T-1 controls these two functions independently. Both mean the control board has detected an operation problem in temperature control for that specific circuit and instructs the owner to call for service, which is stronger language than most other messages on this platform use. Whichever of the two appears identifies which circuit is affected, and it is worth noting which one shows on the display before calling for service, since it tells the technician exactly where to start.

Symptoms
A Dacor coffee machine in this condition usually shows some combination of the following, so match them against your own coffee machine before booking.
- The display shows either “Error – Coffee Temperature” or “Error – Steam Temperature” with buttons disabled.
- Coffee that does brew, if the buttons briefly allow it before locking out, may taste noticeably under-extracted or scalded.
- The steam wand, if the steam-side message appears, may produce weak, inconsistent, or no steam at all.
- The error can appear consistently on every attempt to use the affected function once it starts occurring.
- A burning or overheated smell near the machine’s base can accompany either version of this message.
Common causes
Diagnosis on a Dacor coffee machine means ruling causes out rather than guessing, and these are the ones that matter for Error – Coffee Temperature / Error – Steam Temperature on a coffee machine.
- Failed heating element in the affected circuit — the coffee or steam element is not reaching or maintaining its target temperature.
- Temperature sensor failure in the affected circuit — the sensor is misreading the actual water temperature.
- Wiring failure to the heating element — a loose or corroded connection interrupts power delivery.
- Main control board failure — the board is not responding correctly to sensor input for that circuit.
- Scale buildup on the heating element — mineral deposits from hard water can insulate the element and prevent normal heat transfer.
Troubleshooting steps you can try
Nothing below requires opening the coffee machine up, and every step rules something out about Error – Coffee Temperature / Error – Steam Temperature before a technician touches your Dacor coffee machine.
- Note exactly which of the two messages is displayed, coffee-circuit or steam-circuit, before contacting anyone for service.
- Power the machine off completely at its main switch rather than leaving it in a problem state.
- Do not attempt repeated brewing or steaming while either temperature error is displayed.
- Check when the machine was last descaled, since mineral buildup is a common contributor to temperature problems on either circuit.
- Avoid using the affected function again until the specific circuit has been checked.
Parts a technician may replace
The coffee-circuit heating element, steam-circuit heating element, temperature sensor, and main control board are what a technician examines on a coffee machine showing this problem. Genuine parts are fitted to the coffee machine, matched to your exact coffee machine rather than to the family it belongs to.
When to call a technician
The manual itself instructs calling for service for either temperature error, and given the platform’s discontinued status, a technician should confirm the specific circuit and check parts availability before proceeding. At High severity the safest thing to do with the coffee machine is stop, cut power or water to the coffee machine at the source if anything looks wrong, and call. Nobody here works for Dacor; we are an independent service, and the work we do on your coffee machine is warranted for 30 days.
