Coffee maker drips coffee onto the warming plate even when not brewing.

Clean drip stop:

• Remove the brew basket and rinse thoroughly.
• Operate the drip stop valve by hand under running water to clear debris.

Inspect seals:

• Check the rubber or silicone seal on the drip stop for wear or deformation.
• Inspect the carafe lid for cracks or warping that could affect sealing.

If dripping continues, replace the brew basket/drip stop assembly or carafe as needed.
