My 5-6-year-old Expobar Office Lever just started emitting a hissing noise and steam from the top of the machine.

Noise and steam start as soon as the machine heats up and continue until the machine is turned off and has cooled down again.  It is working OK but I would like to know if there is anything I can do to stop the steam/noise, and what this problem means.  I recently moved to Manila, The Philippines.

It sounds like you might need to clean out the safety valve and/or the vacuum relief valve, or even replace one of them-I'd suggest cleaning first, it's very easy and will usually clear up the issue.  For instructions, please contact our Technical Support team at 1-888-411-5282, option 3 (Technical Support is available Monday through Friday, 9:00 a.m. to 6:00 p.m., and Saturday, 10:00 a.m. to 3:00 p.m., EST.) or send us an email at, and we can email you the instructions.
