  If the brew cycle on your Grindmaster Coffee Maker won't start, check the following: * The optional momentary switch, which indicates if the container is in place, is not engaged or is faulty. If a fully engaged switch doesn't complete the circuit across its terminals, replace it. * The brew circuit connections aren't secure. Ensure all connections are properly secured. * The brew valve is faulty. If there's 24 Vac across the terminals but the brew valve isn't opening, replace the valve. * The touchpad is faulty. If the connections are secure, other functions appear normal, and the touchpad still won't start a brew cycle, replace the touchpad.
