The Home Office, that is…
5 gallon (20L?) water bottle on top, taps below for chilled and heated water. Digital display / controller on top just forward of the water bottle.
This Whirlpool unit (model WHKM-D30) neither heats nor chills. The display allows selection of 3 temperature settings for each heating and chilling (low, med, high). The controls seem to operate visually but no evidence of the chiller compressor starting nor of heat being generated.
My question is: do these things have a “water present” sensor? I presume if the unit was completely dry, there is some safety circuit that would disallow both heating and chilling to initiate?
Looking for a common failure point and this seems a likely item. But maybe there is a different method of disallowing heating and chilling?
Or is the controller just borked?
