SUBJECT: Troubleshooting 1016BVM

Model 1016BVM brewers utilize electronic control boards for timing and

power switching functions. While it is tempting to immediately replace

these electronic components in the case of equipment malfunction, they

are, in fact, generally quite reliable and are seldom the root cause of the

problem. Learning the unique characteristics of these controllers will help

the service technician diagnose problems and return units to service more

efficiently.

We have recently experienced a high number of warranty claims where

the probe and both boards have been replaced. It is highly unlikely that

all three parts would fail simultaneously. Tests of returned boards and

probes show a very high percentage to be non-defective.

This brewer incorporates several features that render strictly intuitive

troubleshooting ineffective:

• Unit is equipped with a high wattage heating element coupled with

programmed action to insure rapid temperature recovery. The heater

is energized near the start of a brew cycle and remains energized until

the water inlet solenoid is de-energized. Water supply volume and

pressure during the brew are critical. Insufficient water volume during

a brew will allow the heater to boil available water, causing the unit to

overheat. Symptoms include very little water dispensed during a

brew, a general fault (all lights flashing) and/or tripped hi-limit safety.

• With traditional mechanical thermostats it is common procedure to

adjust settings during a brew. This is not possible with this control

board. Programming examines water temperature when it receives

a brew signal, and brew cannot start until water is at the setpoint

temperature. So that a brew is not interrupted by the influx of cold

water, once a brew is initiated, programming does not look at tank

temperature again until brew is completed. Neither setpoint, brew

time nor dripout time may be adjusted during a brew.

Attached is a comprehensive troubleshooting guide for your use in

diagnosing problems with this brewer. We fully expect that use of this

guide will eliminate unnecessary replacement of good parts, as well as

improving technician knowledge of, and comfort level with, this equipment.
