SOLUTION
Verify unit is plugged to a 120V/15 amp rated outlet and
power switch in the ON position.
1. Make sure water is turned on.
2. Make sure water pressure is above 20 PSI
3. Clean out any debris at the water inlet behind the
brewer.
4. Make sure power is reaching solenoid valve and
that the solenoid valve is working. Replace
solenoid if necessary.
Add water to proper level on reservoir.
Make sure that the water shut off valve is opened.
Adjust volume of beverage on screen. If error persists,
perform descaling procedure.
Ensure reservoir tank is not filled above maximum fill
level. Perform descaling procedure.
If Pour-Over model, ensure the water inlet valve is
capped with the cap that has been provided with the
brewer.
Remove drain tube cover and verify that the drain line is
properly plugged
Water conductivity is too low for level sensing circuit.
Do not use RO, DI or distilled water.
Hi-limit tripped. Check and repair heating circuit to de-
termine fault before resetting hi-limit thermostat. Check
level probe has not shorted to tank to allow dry-fire.
Triac failure.
Temperature set point too high. Reduce temperature
set point at least 5 degrees and re-check.
1. Clogged outlet. Clean outlet probe with a paper clip
and rinse thoroughly.
2. Faulty capsule seal. Determine if isolated to
specific product capsules.
3. Sticking pressure bypass valve. Lubricate seal and
ball with food grade silicone lubricant.
4. Faulty capsule seals.
5. Soluble capsule product is not compatible with
brewer. Determine if isolated to specific product
capsules.
6. Capsule holder is not snapped into carrier correctly.
Ensure capsule holder is completely secured onto
carrier.
1. Pressure bypass is leaking or stuck open.
2. Upper inlet probe is clogged. Gently insert a paper
clip into probe with caution not to disturb duckbill
check valve; run a water cycle to clear the probe.
