CAUTION

SHOCK HAZARD

Live electrical circuits may

be exposed while performing

these procedures.

These procedures are to

be performed by qualied

technical personnel only.

ERROR DETECTION

The 1016BVM brewer is designed to perform a continuous internal

diagnosis, and to signal faults by ashing all the lights. In fault

mode, warmers, heating element and water ll solenoid are turned

“off”, and most keypad functions are disabled.

Error detection (all lights ashing) will occur under two conditions:

Anytime a temperature in excess of 214ºF is detected.

Temperature does not change by at least 2ºF within 4 minutes

of tank heater being energized (HEAT light on).

To reset the brewer after the fault has been corrected, press and

hold the CANCEL key for 3 seconds, or disconnect the brewer from

electrical power for three seconds.

WHAT TO CHECK DESCRIPTION CORRECTIVE ACTION

Has the water tank been

properly lled?

On initial startup, an attempt to heat a dry tank

will be detected as too high a temperature or

insufcient temp rise, or will trip the high limit.

Tank must be properly lled as detailed on

page 6. Check hi-limit (see below)

Has hi-limit safety thermostat

tripped off?

Brewer may have been started without water

in the tank, or the temp control thermostat may

require adjustment.

Access hi-limit by removing front panel. Hi-

limit is on the left side of the tank. Use an

insulated tool to push the red button in until it

“clicks” and stays. Reset per above.

Check control board and temp

probe.

Brewer will go into error mode immediately

if either the control board or temp probe is

defective. Temp probe electrical resistance

is approximately 30KWat room temp, and

2KW at boiling. Replace temp probe if less

than 1KW

Reset by holding the CANCEL key for

3 seconds. If lights continue to ash:

Disconnect temp probe from control board.

a. If lights continue to ash, unplug brewer

and replace control board.

b. If lights stop ashing, unplug brewer and

replace temp probe.

Check power board and

heating element.

Brewer will go into error mode 4 minutes after

energizing the heating element if insufcient

heat rise is detected. The heating element

is energized by an electronic power board,

and protected by the hi-limit safety. Heating

element should receive full line voltage (i.e.

120V, 208V or 240V). Be sure the hi-limit

safety is reset.

Reset by holding the CANCEL key for 3

seconds. If lights resume ashing after

4 minutes: Check the voltage across the

heating element terminals:

a. If no voltage is present, unplug brewer and

replace power board.

b. If proper voltage is present, nplug brewer

and replace tank heating element.

Is the brew temperature

properly adjusted?

The brewer may occasionally go into error

mode if the brew temperature is set too high.

See page 17 for temperature

adjustment procedure.
