PROBLEM

 

PROBABLE CAUSE

 

REMEDY

No bypass water

 

1. Bypass valve

 

Test the bypass valve. Refer to the

 

 

 

 

test outputs procedures on page

 

 

 

40.

Spitting or unusual steaming from

 

1. Lime buildup

 

Inspect the probe and tank assembly

sprayhead or air vent.

 

 

 

for excessive lime deposits. Delime

 

 

 

 

as required.

 

 

2. Temperature probe

 

Remove the probe from the grom-

 

 

 

 

met and submerge in a water bath

 

 

 

 

of approximately 70°F (21°C).

 

 

 

 

Connect an ohmmeter to the pins

 

 

 

 

in the connector. At 60°F (16°C),

 

 

 

 

the reading should be 15.3k ± 2k

 

 

 

 

OHMS, at 70°F (21°C) the reading

 

 

 

 

should be 11.8k ± 2k OHMS, and

 

 

 

 

at 80°F (27°C) the reading should

 

 

 

 

be 9.3k ± 2k OHMS. If the probe is

 

 

 

 

within these parameters, reconnect

 

 

 

 

to the control board.

 

 

3. 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 40. 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.
