PROBLEM

 

PROBABLE CAUSE

 

REMEDY

Water will not heat or display shows

 

4. Tank heaters

 

Remove power from the brewer.

HEATING TIME TOO LONG.

 

 

 

Check for continuity between the

(Continued)

 

 

 

white terminal of the terminal block

 

 

 

 

(or red terminal on 208/240V mod-

 

 

 

 

els) and the black wire on the relay

 

 

 

 

on the control board (Toggle switch

 

 

 

 

must be in 120/208-240V position

 

 

 

 

on 208V and 240V models). There

 

 

 

 

should be a low OHM reading. If

 

 

 

 

not continuity is present, check for

 

 

 

 

a wiring or switch problem (consult

 

 

 

 

wiring schematic), then replace the

 

 

 

 

tank heater if no wiring or switch

 

 

 

 

problem is found.

 

 

5. Control Board

 

Remove power from the brewer.

 

 

 

 

Connect a voltmeter across the

 

 

 

 

tank heater. Reapply power to the

 

 

 

 

brewer and refer to testing outputs

 

 

 

 

on page 56. If the voltage measured

 

 

 

 

when the tank heater is turned on

 

 

 

 

is very low or zero, then substitute

 

 

 

 

a control board know to be good

 

 

 

 

working order.
