Problem

Possible Cause

Solution

Brew cycle will not start or water
does not come out.

No water to machine (check by
opening hot water spout).

Red autofill light stays on
continuously.

Water leaks while brewing coffee.

Water leaking from group head or
exhaust pipe in drain basin.

Water leaking from opposite side
of group head in use.

• No water (check by opening hot

water spout).

• Flow restrictor/doser in group 

head is clogged.

• Improper filter in filter holder or

clogged filter.

• Spray deflector or group 

strainer is clogged.

• Switch or solenoid valve faulty.

• Water supply valve closed.

• Water filter may be clogged.

• Water is off.

• Water pressure too low 

(minimum pressure should be
25 PSI).

• Faulty float switch.

• Group head gasket has 

hardened or broken.

• Solenoid stuck open.

• Too much pressure.

• Weakened solenoid springs.

• See section on "no water to

machine".

• Check to be sure filter (with  

holes) is being used and is not 
clogged.  Clean if needed.

• Check to verify spray deflector or

group strainer is not clogged.
Clean or replace if needed.

• If only one side is not working,

check to see if switch or solenoid
valve has failed. Replace if needed.

• Check to be sure all water valves

are open (Machine valve, water
filter valve, main supply valve).

• Shut off valve preceding filter.

Open filter housing. Open valve
to check if water comes out.
Replace filter if needed.

• See section on "no water to

machine".

is weak, slow or steamy, check for
closed valves or partially opened
valves. Check for clogged filter,
interruptions to water supply line or
other appliances using water that
may be reducing water pressure.

• Open steam wand. If steam is

watery, see section on "steam is too
watery".

• Replace gasket if needed by prying

out.

times. If problem continues,
replace solenoid.

• Replace solenoid valve if needed.
