TROUBLESHOOTING

Steam Wand

 

 

 

Drip at the Steam Wand Tip: 

Steam valve seal is worn. Replace by installing steam valve rebuilt kit. 

Steam valve is filled with milk residue. Disassemble steam valve and clean. 

 

Wand is Hard to Move or Sticky: 

Remove wand at the nut, clean and lubricate moving parts with food grade grease 

 

Steam

 

Sudden loss of steam pressure: 

Commonly caused from drawing large amounts of hot water while steaming milk. Allow the 
machine time to recover pressure. Check temperature settings on Steam 1 and 2 to make sure 
they are high enough for your application. Watch the steam gauge when the pressure drops; allow 
the heating elements to heat the incoming cold water. When it reads above 1.1 bar, hot water and 
steam may be dispensed again. 

Check the programming keypad to make sure all temperatures, especially in the steam tank, are 
close to their set points. 

Check the element breaker on the electronics box to make sure the heating elements are ON 
(element switch is to the left). 

 

Steam Tank is overfilling: 

Water is too soft; this occasionally happens with reverse osmosis water filtration systems. The 
water level (auto fill) probe needs a minimum mineral content in order to detect water. 

Debris caught in the water control valve or worn out valve. 

Calcium deposits on the fill probe are preventing the probe from detecting the water level. 

 

Steam Valve Stem Seals Leak: 

Replace O-rings. Purchase Rebuild Kit 

 

The Sight Glass shows over or under filled steam tank 

Machine is not level. Check to make sure the surface that holds the machine is level. Slightly 
adjust leg height to level the machine. 

Water level is too high; use the hot water spout to drain water from the steam tank. Continue 
releasing hot water until the autofill system activates. Once autofill stops, recheck the water level. 

Debris is stuck in the water control fill valve.
