heavily you may need to restrict the flow rate out of the faucet. Note: The maximum run time for the fill solenoid is
5 minutes.

Err: Safety Probe
are wired in reverse; or there is a break in the wiring to the safety probe from the board. If the problem is the result
of lime insulating the metal surface of the probe, clean or replace probe. If the problem persist, Check the wiring to
the probes. The water level probe is the shorter probe mounted in the sidewall of the water tank and is connected
to the board with a yellow wire. The heater safety probe is mounted in the tank lid and extends further down into
the tank then the water level probe does. It is connected to the board by a yellow wire with a red stripe. If the
correct colors appear to be going to the corresponding probe use the wiring diagram, Fig 3, Page 11, to ensure
that the wires are terminated in the correct spot on the board connector. If the connections appear okay check the
continuity between the connector end on the board of the probe wire and the quick connect terminal on the probe.

thermistor (temperature sensor) you will need to remove the top cover and rear panel of the brewer. Loosen the
wire nuts to the thermistor and use a continuity tester to check for continuity between the 2 wire thermistor leads. If
there is no continuity the sensor needs to be replaced.

Err: Shrt Tmp Sensor
you will need to remove the top cover and rear panel of the brewer. Loosen the wire nuts to the thermistor and
using a continuity tester check for continuity between each of the 2 wire thermistor leads and the tank. If there is
continuity between either of the wires and the tank the sensor needs to be replaced.
Error Messages
Err: Bad Heater Elem
With a continuity meter check to see if the tank element and the safety limit thermostat have continuity. If a manual
reset safety thermostat is installed in the brewer check to make sure the red button is pushed in. If both of these
components check out okay, then you will need to replace the heater relay. The relay is located in the lower rear of
the brewer mounted on a bracket to the side of the brewer column.
Error Messages
Err: Faucet Timeout
closed when error was generated check the wiring connections on faucet microswitch and verify microswitch
operation (opens and closes circuit as it should) using a continuity tester.
Other Errors or Problems
Brewer Display Will Not Light Up
The brewer may not be receiving power. Check for the correct voltage at the electrical receptacle. The brewer
serial tag will indicate the correct voltage for the unit. If voltage is present there are 3 other areas which should be
checked in the following sequence.
Unplug brewer and remove top cover as well as the rear back panel.
1. Check the fuse located on the upper display board located behind the front control panel of the brewer.
If fuse is blown replace.
2. Check the ON/Off power switch for continuity which is located at the front of the brewer. Access to the
switch is through the rear back panel. If the switch does not make & break contact , replace switch.
3. Check transformer. Transformer output should be 16-24 volts.
This error occurs when the water level probe senses water and the heater safety
probe does not. 3 conditions can normally produce this error. These conditions
are: The probe has scaled over; the water level probe and the heater safety probes

This message displays when the brewer has tried to heat the tank to the preset
temperature for a period of time exceeding 30 minutes. There are 3 areas which
should be checked. Unplug the brewer and remove the top cover and rear panel.
This message displays when the faucet has been open for a period exceeding four
minutes. The brewer is inoperative until the condition is corrected and the error is
reset to prevent possible flooding. Close the faucet to correct error. If faucet was
