SERVICING INSTRUCTIONS — DIAGNOSTICS & TROUBLESHOOTING)

If the E-Max™ LX goes into an error mode as outlined below, it will probably be necessary to reset the brewer in order to test individual components. Note the reset procedure below:

*FOR “LOW WATER” OR “OVERHEAT” ERRORS: PRESS & HOLD CANCEL FOR 3 SECONDS, OR RE-ENERGIZE THE BREWER (i.e. unplug for a few seconds, the plug in again.)

*FROM “VALVE FAULT” ERROR: THE BREWER MUST BE RE-ENERGIZED Using the CANCEL button will not reset the brewer from “Valve Fault”.

IMPORTANT: The following troubleshooting suggestions are for operator reference only.

All servicing and/or repairs must be performed by a qualified technician.
