- Page 11 fig.16 fig.17 7 – Take out the resistance (see fig.17). 8 – Fit in the new resistance with the 2 new O-ring washers. 9 – Reassemble the whole unit carrying out the operations in reverse order.
- Page 12 3.3 – When you press the coffee switch (2)(fig.18), the pump goes on in a very noisy way, but no coffee comes out of the pipe (11). fig.18 Reason: Pump empty due to lack of water in the tank or to emptying or to an air bubble in the pump suction pipe.
- Page 13 3.4 - When you press the coffee switch (2), the pump goes on but no coffee comes out of the spout (11) and water comes out of the hot water pipe (9) (see fig. 19 and 20). fig.19 fig.20 Possible reasons: The solenoid valve (e1) may be dirty or faulty, and therefore stays locked in its open position (see fig.
- Page 14 3.5 - When you press the water delivery button (4) (see fig. 23), the pump goes on but the water exits through the by-pass (c1), instead of coming out from the relevant pipe (9), and goes into the tank (short pipe). Reason: The solenoid valve (e1) is faulty, so it stays locked in a closed position (see fig.24).
- Page 15 3.6 – When you press the coffee delivery button (2), see fig. 27, the pump goes on, but no coffee is delivered from the relevant pipe (11). fig.27 Note The water could exit through: a - the by-pass (c1), into the tank (short pipe)(fig.27a); b - the solenoid valve e3, locked in the open position, into the steam boiler.
- Page 16 3.7 – During the steam boiler water level renewal phase, the pump goes on working for a maximum time of 2 minutes, leading to safety stopping of the machine. Possible reasons: The solenoid valve (e3) stays in its locked closed position and the water, instead of flowing into the steam boiler, overcomes the restriction of the by pass (c1) and flows into the water tank.
- Page 17 3.8 – Continuous dripping from the coffee spout when the machine is on, even when it is not working. Possible reasons: a – The solenoid valve (e2) is dirty or faulty and stays in open locked position (fig.28). b – Inside injector of the boiler is broken or lacks sealant on its threaded ends.
- Page 18 fig.28d fig.28e If the pipe stays fitted inside the boiler, you can make the following attempt: fig.30 Try to unscrew the pipe using pliers(fig.30). If the pipe comes out unbroken, replace it as follows: - Empty the boiler (to make this operation easier, remove the bottom shower of the boiler).
- Page 19 - Open the boiler (see fig. 32). - Remove the injector (see fig. 33) - Replace the pipe fig.32 fig.33 - Reassemble the unit proceeding in the reverse order. Make sure that you put the sealant properly on the new injector: first on the threaded part screwed into the bottom of the boiler and then – after the boiler has been reassembled - on the top threaded part before screwing back on the hexagon coupling (see fig.30).
- Page 20 fig.28b fig.28c Remove the curve T2 (see fig.28b) Unscrew the hexagonal manifold R1 (see fig. 28c) fig.28d fig.28e Take the manifold out of the boiler (see fig. 28d) Replace the 2 OR 2018 (see fig. 28e) fig.28f NOTE Reassemble all parts, proceeding in the reverse order (see fig. 28f) and put the sealant on the 1/8” coupling thread.
- Page 21 3.9 - When you press the water or coffee switch, the pump is not turned on. Possible reasons: a) Faulty water or coffee switch. b) Pump burned c) Automatic operation of pump temperature protection thermostat (at 110°). Operations: a) Try to activate the pump by pressing the opposite switch, i.e. if you previously pressed the water switch, now press the coffee swtich and vice ersa.
- Page 22 3.9A – The machine causes the automatic differential switch to trip, in order to protect the power line it is connected to. Possible reasons: d) Short-circuited resistance e) Short-circuited solenoid valve f) Pump burned g) Other (See final summary page on “Troubleshooting”). Operations: a) See paragraph 3.2, operation C.
- Page 23 3.10 – Steam boiler pressure fault Possible reasons: a) Miscalibration of the pressure switch. b) Fault on the pressure switch (contact open, the boiler cools) Fault on the pressure switch (contact closed, the boiler reaches 2 Bar pressure and releases the steam through the safety valve). Operation: a) Adjusting the pressure switch through the top hole of the dividing plate of the steam boiler (see fig.36).
- Page 24 3.11 – The steam boiler does not heat The Blitz Coffee and cappuccino machine is equipped with a 1000 cc stainless steel boiler for making steam. The following components (fig.37) control the operation of the boiler: - Feeding solenoid valve - Resistance (7) - Pressure switch (2) - Anti-recall valve (3)

- Page 27 3.12 – Fault with steam output during working phase. During a normal working phase, we should have the following conditions in the steam boiler: Working pressure governed by the pressure switch at 0.9 – 1.3 Bar Safety valve (4) set at 2 Bar ,see fig.42 Anti-depression valve (3) closed.
- Page 28 Operations: a –Pressure switch miscalibrated b – Pressure switch faulty (with contacts closed) Operation a: Adjusting the pressure switch through the top hole of the dividing plate of the steam boiler (see fig.43). fig.43 Operation b: – Replace the pressure switch (see fig.44) fig.44 Operation: - Calibrating the safety valve.
- Page 29 - Unscrew the screw of the pressure switch (see fig.43) and let steam out by pressing the button (3c) (see fig.46) in order to reduce pressure in the boiler, until the pressure on the pressure gauge is set at 0.9 -1.2 Bar. fig.45 fig.46 Operation 2:...
- Page 30 The anti-redepression valve must open up when the boiler cools down, and must close when the boiler heats up again. If the anti-redepression valve does not close properly, when the boiler heats, steam will come out. Note The anti-redepression valve could also stay locked in a closed position. In this case, when the boiler cools down inside, a depression is created inside it;...
- Page 31 3.13 - Faulty water output from the safety valve of the boiler during coffee delivery phase. Possible reasons: 1 - Electronic station faulty. 2 – The solenoid valve (e3) (fig.48) stays in its locked open position, and water flows out into the steam tank. Important! : Failure to recognize this problem leads to total filling of the steam boiler and then to water coming out of the steam safety valve.
- Page 32 fig.49 fig.50...
- Page 33 3.14 – If steam delivery is requested, the pressure switch shows zero pressure and the steam delivery stops immediately. Possible reasons: 1 - Electronic station faulty. 2 - The solenoid valve (e3) (fig.48) stays in its locked open position, and water flows out into the steam tank.

- Page 36 4.2A – When selecting a coffee (high or low coffee level), a quantity of coffee different from the preset one is obtained. Possible reasons: - The volumetric counter 15 (see fig.55) is dirty or faulty. Operations: - Clean the dirty counter. 4.2B- When selecting a coffee (high or low coffee level), the delivery does not stop unless the C/S button is manually pressed.
- Page 37 These doses have already been stored into the electronic station by the manufacturer. They are set to 20cc. for a low-level coffee and to 40cc for a high- level coffee, and are used to check the proper operation of the machine. To obtain this preset dose, press the C/S button (18) for at least 10 sec.
- Page 38 If the plug is mounted in a wrong way, this will lead to failure of the counter, making it unusable. fig.58 TECHNICAL NOTE: After cleaning or replacing the volumetric counter, we suggest to test coffee delivery (without pod) using the preset doses so as to check the proper dose quantity and repeatability. This function is also useful to reset any programming errors (zero dose programming).
