SERVICE MANUAL COFFEE VALVE Fig. 102 Each unit is provided with a three-way valve called coffee valve. It is a solenoid valve that is normally closed and opens when it received a command to dispense coffee. When this valve is closed the liquid that remains in the hydraulic circuit is pushed by pressure towards the third valve passage, connected to the wastewater collector.

SERVICE MANUAL Turn off the water inlet to the pump. Fig. 113 Once you see that there is no more steam Fig. 114 and pressure in the boiler, lift the lid on the exhaust manifold. With a No. 17 key unscrew the bolt inside Fig.
SERVICE MANUAL ACCESS TO THE HEATER To access the heating elements and the visible parts of the heater: Loosen the two Phillips screws on the upper Fig. 116 right side of the cup warmer and carefully remove the side Fig. 117 The visible parts are: the level probe.
SERVICE MANUAL HEATING ELEMENT AND HEAT PROTECTION The main heater of VA388 T3 has the following resistances: There are three heating elements, one for each Fig. 119 phase, therefore, in the terminal box we find the neutrals connected in parallel (N) and the three phases which arrive each to a different element, perfectly distributing the absorption of the current.
Page 56
SERVICE MANUAL Remove with care the panel out of its slot. Fig. 122 Fig. 123 NOTE Each time you replace the heating elements is also necessary to change the Teflon O-ring that isolates it from the heater because it is a part subject to wear, therefore the component it must be ordered together with the heating elements.
SERVICE MANUAL REPLACEMENT OF THE Fig. 124 LEVEL GAUGE The water inside the heater is maintained at a constant level through the use of a level probe inserted inside the heater. This probe is connected to the electronic control unit that continuously polls the probe. Being always exposed to high temperatures and steam/water it is subject to encrustations which can inhibit operations.
SERVICE MANUAL ANTI-SUCTION VALVE Fig. 128 The anti-suction valve ensures that air enters the heater during the machine cooling phase. In this way the reduction of water volume due to cooling does not create decompressions that may give rise to drawbacks such as the suction of milk through the steam nozzle.
SERVICE MANUAL SAFETY VALVE Fig. 130 The steam safety valve is made to open at the pressure of 1.8 bar. If necessary, it can be replaced using a key to lock the tube that carries the steam and unscrew the entire assembly. WHEN TO REPLACE For safety reasons each time the valve comes into operation it should be replaced to ensure...

SERVICE MANUAL The holes of the injector tend to become clogged Fig. 165 if the operating water is not optimally softened or after several months of work. 98030500 For this reason, we recommend that the injectors be replaced once a year. To remove the injectors it is necessary to drain Fig.
Page 72
SERVICE MANUAL HOW TO CHECK THE OPERATION OF THE INJECTOR? Should it occur that one unit dispenses less water than the others check to see whether the problem is related to the injector that has accumulated too much limestone. The following instructions are indicative because the result will depend on the incoming water pressure.
SERVICE MANUAL Reopen the tap of the pump taking care to Fig. 172 place an appropriate container (e.g. Milk jug) below the nozzle. IF THE FLOW THAT ARRIVES IS REDUCED Check if upstream of the heater the water flow is minor. If also at the exit from the heat exchanger the flow is minor the problem is upstream, probably in the fitting that injects cold water into the heat exchanger or in the...
