Cuisinart coffee maker issues with water leaks

If your Cuisinart coffee maker is leaking from the base, it is most likely that one of the internal hoses through which the water circulates is loose or broken. The hoses attached to the resistance typically deteriorate owing to abrupt temperature swings in Cuisinart coffee makers, which leads to minor cuts where the hose meets the water heater and water eventually escapes.

You will need wire cutters, needle nose pliers, a CR-VT10 security Torx screwdriver, a small flat-blade screwdriver, and silicone (optional) if you discovered the leak at the heater and hose junction.

Step-by-step repair:

  • Turn off and unplug the coffee maker.
  • Make certain the water tank is empty.
