Voltage Measurement Safety InformationWhen performing live voltage measurements, you must do the following:

n Verify the controls are in the off position so that the appliance does not start when energized. n Allow enough space to perform the voltage measurements without obstructions. n Keep other people a safe distance away from the appliance to prevent potential injury. n Always use the proper testing equipment. n After voltage measurements, always disconnect power before servicing.

IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. Most people begin to feel an ESD discharge at approximately 3000V. It takes as little as 10V to destroy, damage, or weaken the main control assembly. The new main control assembly may appear to work well after repair is finished, but a malfunction may occur at a later date due to ESD stress.

n Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance

-OR-

n Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

n Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance.

n Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

n When repackaging main control assembly in anti-static bag, observe above instructions.

For Service Technician Use OnlyComponent Testing Chart

Unplug coffee system or disconnect power before performing the following checks:

n A potential cause of a control not functioning is corrosion on connections. Observe connections and check for continuity with an ohmmeter.

n All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 Ω per volt DC or greater.

n Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough. Damaged harness must be entirely replaced. Do not rework a harness.

n Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.

Do not continue with the diagnosis of the appliance if a fuse is blown, a circuit breaker is tripped, or if there is less than 120+10%/-15% volt power supply.The coffee system must be unplugged or the power disconnected when measuring resistance.When checking for proper voltage, complete the following steps:
