G4 BREWERS WITH SSR, TROUBLESHOOTING GUIDE 122717A
Water Does Not Heat At All
Check to see if the water level in the tank is in contact with the water level probe. If not, see Tank Does Not Fill.
The water will not heat unless it is in contact with the probe.
If the water heats, but is not hot enough, see Water Not Hot Enough.
• If Ready to brew appears on the display, but the water is not hot, check the resistance across the leads of the
temperature sensor. If the resistance is less than 10 k and the water is not hot, replace the temperature sensor.
If the sensor resistance is above 10 k when the water is cool, replace the universal power module (UPM).
If Heating... appears on the display, but the water is not hot, follow the steps below. The following steps are
performed with the rear toggle switch in the ON position.
1 Check for power across the terminals of the heating element(s). If power is being supplied, remove the wires
and check for an open heating element.
2 If there is no power to the element(s), trace the circuit back (using the ELECTRICAL SCHEMATIC) to the power
DPSEUPmOEPVUXIFSFQPXFSJTMPTU*GUIFSFJTQPXFSJOUPUIFTPMJETUBUFSFMBZT443TCVUOPUPVUTFFUIF
following step. On units having two SSRs, be sure to check both.
3 If there is power into a SSR, but not out, check for 5 Vdc (nominal*) across the + and - pins of the SSR(s). If
there is 5 Vdc across the + and - pins of the SSR(s), but no (or low) output voltage at a SSR output terminal,
replace the SSR. If 5 Vdc is not being supplied from the UPM, but Heating... appears on the display, check
the wiring from the UPM to the SSR(s). If the wiring is OK, replace the UPM.
Water Too Hot (Boiling or Excessive Steaming)
1 If Over Temp Sensor or Ready to Brew appears on the display and the water is too hot, go to Over Temp
Sensor Error Message.
2 If the display reads HeatingDPOTUBOUMZmSTUDIFDLUPNBLFTVSFUIBUUIFUFNQFSBUVSFTFOTPSJTBUUBDIFEUJHIUMZ
to the tank and that heat sink compound was used. A properly mounted sensor should have a resistance of
around 7 k when the water is hot. If not, replace the sensor.
3 Check to see if the universal power module (UPM) constantly has +5 Vdc (nominal) output to the solid state
relay (SSR), regardless of the resistance of the temperature sensor. If so, the UPM is probably bad.
4 If the UPM is working properly, check for a shorted SSR.
Over Temp Sensor Error Message
This error message indicates that the universal control module (UCM) has detected a water overheating
problem. The universal power module (UPM) is reading a water temperature in the tank above 210ºF. If the water
temperature is too hot, but Heating... appears on the display, see Water Too Hot. Once the malfunction causing
the error is corrected, the error message must be cleared. To reset the brewer and return to normal operation, turn
the toggle switch on the back of the brewer to the OFF position for 5 seconds, then back on.
1 Check for 5 Vdc (nominal) across the + and - pins of the solid state relay (SSRs). If no power is applied to the
SSR and the heating elements are always on, replace the SSR. On units having two SSRs, check both.
2 Turn off power to the brewer and allow the water tank to cool. Once cool, turn power back on while monitoring
the voltage across the + and - pins of the SSR(s). During normal operation, the voltage should be 5 Vdc,
until the water is hot, then drop to below 1 Vdc. The universal power module (UPM) should be replaced if the
voltage reads 5 Vdc constantly even though Ready to brew or Over Temp Sensor appears on the display.
3 If the UPM is operating normally, check for a false over-temp error caused by the temperature sensor. Check
the resistance across the leads of the temperature sensor. If the resistance is less than 10 k when the water is
cool, replace the temperature sensor.
IMPORTANT: Before proceeding, make sure that the control panel temperature is adjusted to compensate
for higher elevations. The factory setting is 200°F. Reduce the temperature setting two degrees for every
1000 feet of elevation above 4000 feet.
