Troubleshooting Guide
Diplomat II Pour-Over Coffee Brewer
Read and follow the cautions below before attempting to service this coffee brewer.
Caution:
Read and verify that the installation instructions have been followed before attempting to operate this
appliance. Incorrect installation or operating procedures will void the warranty and may damage this
appliance.
Unplug the power supply cord before servicing, unless electrical testing is required. Be certain
the power supply is of the correct rating and polarity before connecting the power supply cord. The
chassis must be grounded to prevent possible electric shock. Failure to heed this warning may damage
this appliance and may cause injury.
This appliance is equipped with an automatic temperature limit control designed to turn the appliance off
if it overheats. In that event, do not reset until a qualified service representative has inspected and
repaired the appliance. Under no circumstances should the temperature limit control be bypassed or an
alternate control used, as a fire risk could result.
Under no circumstance should the hi-limit thermostat be by-passed. In the event of failure the
hi-limit thermostat should be replaced. Use only original or authorized replacement parts.
Carefully inspect the internal wiring for wear or damage when servicing. Worn or damaged wiring may
cause malfunctions and premature component failures. Replace any wires that have loose
connections, damaged insulation or show evidence of overheating. When repairing or replacing internal
electrical wiring, in part or in whole, use only terminals and wires with the same rating, gauge and
insulation covering.
See the separate instruction sheet that was included with this manual for testing and cleaning the
Diplomat model coffee brewers. These instructions contain valuable information on servicing and
cleaning that may extend the service life of these brewers.
Symptoms Solutions

Check the main circuit breaker in the building to see if it has
tripped.
Reset or replace the hi-limit thermostat.
Test the power switch. Replace it if necessary.

Check to make sure the internal wiring is correct. Inspect for
loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
4. Primary or secondary hi-
limit thermostats keep
activating.
Machine power has been left on overnight or for a long period of
time without being used. Refill tank with water and wait for
machine to reach operating temperature.
Note: Turn machine off overnight or when not in use for a long
period of time.
Test the hi-limit thermostat. Replace it if necessary.
Test the thermostat. Replace it if necessary.
Inspect the wiring on the hi-limit thermostat for loose, damaged
or overheating wires or terminals. Repair or replace wiring as

by-passed. In the event of failure, the hi-limit thermostat
should be replaced. Use only original or authorized
replacement parts.
5. The coffee brewer trips
the buildings circuit
breaker.
Too many appliances are connected on one electrical circuit.
The electrical circuit’s amperage rating may be too low. Locate
a correctly rated circuit or call an electrician to correct this
problem.
This coffee brewer may require a dedicated wall circuit. Check
the electrical specifications.
Check to make sure the internal wiring is correct. Inspect for
loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
Inspect the immersion element for damage. Replace it if
necessary.

Symptoms Solutions
6. The brewing temperature
is either too hot or too
cold.
The thermostat bulb must be in its clip and attached to the
immersion element correctly.
Inspect the thermostat bulb for excessive lime buildup. Clean if
necessary.
Adjust or replace the thermostat. Turn the adjustment screw
counter-clockwise to increase the temperature, clockwise to
decrease. Turn the adjustment screw a maximum of 1/8 turn
per adjustment. Retest and adjust again if necessary. The
recommended temperature is approximately 190°F. Test below
the brew cone with water only.
WARNING:
If the thermostat cannot be adjusted properly it should be
replaced. The thermostat is calibrated at the factory and no
attempt should be made to recalibrate it. Use only original
or authorized replacement parts.
Check to make sure the internal wiring is correct. Inspect for
loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
7. The brewing cycle is too
slow.
Inspect and clean the spray head, siphon tube and reservoir
down-tube.
8. The beverage level is
inconsistent.
Inspect and clean the spray head, siphon tube and reservoir
down-tube.
Make sure the pour-through lid is closed when not in use.
Make sure the top cover and element gaskets are in place
correctly and are in good condition.
Adjust or replace the thermostat. (See #6.)
9. Water drips from the
spray head for a long time
after the brew cycle is
finished.
Inspect and clean the spray head, siphon tube and reservoir
down-tube.
Inspect the o-ring on the siphon tube for leaking.
Adjust or replace the thermostat. (See #6.)
10. Parts are failing
frequently.
Check to make sure the internal wiring is correct. Inspect for
loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
Test the voltage supply. The voltage supplied should match the
voltage requirement on the electrical nameplate.
Test the wall receptacle for correct polarity.
Use only original, or authorized, replacement parts.

Symptoms Solutions
11. Water leaks from the
bottom of the housing.
Inspect and clean the spray head, siphon tube and reservoir
down-tube.
Inspect the o-ring on the siphon tube for leaking.
Make sure the top cover and element gaskets are in place
correctly and are in good condition.
Inspect the housing for damage or cracks.
12. The warmers will not
heat.

Check to make sure the internal wiring is correct. Inspect for
loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
Test the warmer element. Replace it if necessary.
13. The coffee tastes weak or
does not taste good.
Inspect and clean the spray head, siphon tube and reservoir
down-tube.
The spray head should be in place and clean for proper coffee
extraction.
Clean the area above the brew cone regularly.
Test the brewing temperature. Adjust if necessary. (See #6.)
Adjust the amount of ground coffee being used or adjust the
grind of the coffee. Too much coffee, or coffee that is ground
too fine, may affect the flow of the water through the coffee.
Make sure that the paper filter being used is correct for this type
of coffee brewer.
14. There are coffee grounds
in the brewed coffee.
Inspect the brew cone for wear or damage. Replace it if
necessary.
Adjust the amount of ground coffee being used or adjust the
grind of the coffee. Too much coffee, or coffee that is ground
too fine, may affect the flow of the water through the coffee.
Make sure that the paper filter being used is correct for this type
of coffee brewer.
Two paper filters may have been used accidentally. Use only
one filter per brew cycle.
Fine grind coffees and water softening systems may affect the
way the water flows through the coffee and brew cone, and may
cause coffee grounds to show up in the brewed coffee. There
are several option available to help solve this problem: Extended
brew spray heads, wide base brew cones or a paper filter
designed for faster water flow. Call Brewmatic for complete
details and options.
