What Quench Probe Error
actually means.
Steam and condensate leave a Blodgett combi through a drain, where cold water is sprayed in to cool it before it reaches the building plumbing. A quench probe watches that drain temperature. When its reading is out of range, the control shows Quench Probe Error and can no longer confirm the drain is being cooled.

What to do when Quench Probe Error shows on the commercial applianceKind of codeSensors and probes
A probe is handing the controller a reading it cannot trust, or none at all: a box or coil sensor torn loose from its clip, a fryer probe coated in carbon from oil left too long between filterings, a combi core probe with a kinked cable, or a connector gone green from steam and cleaning chemicals. The unit then runs on, stops, or shuts the heat or the cooling off to protect itself. Letting it cool and restarting it as the manual describes is fair; a probe that still reads wrong sits behind a panel, and that is a visit.

What not to do
Quench Probe Error is not a steam generation problem, and it does not describe the cavity temperature. It concerns the drain cooling system only.
