--- title: "Coffee machine signal Clean Group" description: "Coffee machine signal Clean Group: dacor coffee machine — reported by blinking lights rather than by a code. A counter, not a complaint." url: "https://dacormiami.support/error-codes/coffee-clean-group/" date_modified: "2026-09-12" Appliance type: "coffee-machine" --- # Coffee machine signal Clean Group ### What the appliance is actually reporting A counter, not a complaint. The brew group collects coffee oils and fines with every shot, and the machine asks for a clean at a fixed interval because the alternative is a group that gradually strangles itself. Owners who run this when asked rarely need the group serviced; owners who dismiss it for a year are the ones who call about coffee that has gone bitter and weak at the same time. ### Where this appears, and which table it belongs to On the appliance’s own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all. ### Which machines this one applies to CM24P and CM24T built-in coffee systems. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 5 of the appliance types this site publishes — coffee machine, cooktop, dishwasher, oven and range — and publishes none at all for freezer, microwave, range hood, refrigerator and wine cooler. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door. ### What to do about it - Run the cleaning cycle with the tablet the manual specifies. - Remove and rinse the group by hand as well if it has not been done recently. - If the prompt returns straight after a completed cycle, the counter is not being reset — that is a problem. - Skipping this is the single commonest reason these machines end up needing a service visit. ### Where this goes next The job this usually becomes is [coffee system brew group service](/services/coffee-system-brew-group-service/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 363-6067](tel:+13053636067) and describe what the panel is doing before booking anything.
