Troubleshooting Guide

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problem encountered. If the problem remains after exhausting the troubleshooting steps, contact Grindmaster- Cecilware Technical Service Department (800-695-4500, 8am-6pm, M-F).

Only qualified service personnel should perform inspection, testing, and repair of electrical equipment

Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an intermittent condition is encountered, the cause will likely be a switch contact or a loose wire connection at a terminal or crimp.

The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help avoid twists and kinks in the tubing.

Make certain that all plumbing connections are sealed and all electrical connections are tight and isolated.

This dispenser is heated at all times. Keep away from combustibles.

WARNING:

Exercise extreme caution when servicing electrical equipment.

Disconnect power from the power source when servicing, except when electrical tests are specified. The illuminated blue LCD on the door indicates that the unit is powered ON. Of the blue LCD display is OFF, power is still supplied to some of the internal wiring of the machine.

Follow recommended service procedures.

Replace all protective shields or safety notices.

Replace any worn or missing safety notices.
