Haas 144 alarm: Coolant low flow

The machine detects a lack of refrigerant flow or pressure. It is an alarm from the Coolant area, and in the catalog it is listed as “Coolant low flow”. On the machine you notice it like this: Poco caudal en boquilla, The pump runs but does not deliver enough, Alarm when activating M08.

On the shop floor it almost always comes from one of these causes: Nivel bajo, Clogged filter or nozzle, Damaged pump, Sensor de flujo sucio. Rule out the most likely one on your machine first, before touching parameters or swapping anything.

Reset once flow is restored and M08/M09 checked. Resetting without fixing the cause first only hides the problem: Haas 144 trips again and, in the meantime, you keep working with the machine in bad shape.

With the machine stopped and in a safe state, start with these checks: Comprobar nivel de taladrina, Clean filters and nozzles with the machine stopped, Probar bomba en manual. That alone will tell you whether it is the program or whether you need to raise a maintenance job.

With Haas 144 active, avoid this: Do not machine material/tool that requires coolant if there is no flow, Do not clean nozzles with the spindle turning. Skipping any of these points is what turns a minor stop into an expensive breakdown.

If the pump does not start, protection trips or the sensor does not change after cleaning. If you are not sure how far it goes, stop the machine and report it: a repeat alarm always works out cheaper than a crash.

It is a warning: the machine carries on, but it is flagging something that will get worse if you let it go. Deal with it between parts, not at the end of the shift. The exact code may vary depending on Haas flow sensor option.
