According to the Cuisinart DGB-600BC Grind & Brew Thermal 10-Cup Automatic Coffeemaker User Manual, consumer troubleshooting is safe, but serious repairs should only be completed by Cuisinart-authorized personnel. Taking apart the unit in your own home may lead to electric shock or other injuries, so only non-disassembly troubleshooting should be followed. If your DGB-600BC coffeemaker continues to have problems or is defective, arrange for repair service with a Cuisinart consumer advocate by calling 1-800-726-0190. If you have your three-year warranty and proof of purchase, your repair or replacement may even be covered for free.
Check the size of your coffee filter to reduce overflow. Only disposable standard #4 coffee filters or the Cuisinart-brand Gold Tone filter should be used in the DGB-600BC. Remove any other disposable coffee filter and replace it with the correct #4 size.
Count the number of #4 disposable coffee filters in the filter basket to avoid overflow. Remove any excess filters so that only one filter remains in the basket.
Clean your Cuisinart-brand Gold Tone filter of any excess coffee grounds by rinsing it under cold water to prevent overflow.
Re-grind your coffee less coarsely to avoid overflow. Remove the coarse grounds and fill the coffee basket's #4 or Gold Tone filter with newly-ground, less-coarse coffee.
Unplug the DGB-600BC coffee-maker and wait 10 minutes if water is not draining from the filter basket into the carafe. Re-plug the coffeemaker in and allow the brew cycle to restart.
